A* INTRODUCTION Purpose and Scope The purpose of this study is to identify and evaluate possible changes to U. S. currency which will assist the blind or sight handicapped in distinguishing currency denominations. In developing the recommendation, the study group reviewed applicable design features utilized by other countries as well as features which are or will be practicable as a result of technological developments, and assessed the effect of these features on the production of U. S. currency. B. Background This study was requested by Congressman Edward R. Roybal, Chairman of the House Select Committee on Aging, on February 8, 1983• Significant interest in the development of U.S. currency to assist the sight impaired, however, has existed since the early 1970fs. In January 1971f the Netherlands introduced bank notes with distinctive raised (tactile) symbols for each denomination. In June' of that year, Congressman Rarick of Louisiana introduced H.R. 9102 which would have required the incorporation of braille denomination information in currency. Several similar resolutions were introduced between 1971 and 1981, none of which were passed into law. The Bureau of Engraving and Printing (BEP) has conducted research into methods of denominating currency over the past twelve years, including studies in 1976 and 1980. The 1976 study evaluated the incorporation of braille markings in currency. Experimental currency notes were printed and both the physical characteristics of these notes and the usefulness for sight handicapped individuals assessed. During 1980, research was done to evaluate the potential impact of "notching11 notes in unique locations for each denomination as well as cutting the corners of the notes. Both the Federal Reserve System and the U.S. Secret Service expressed fundamental concerns over problems which might arise during the transition period when notched or corner cut and regular currency would co-circulate* The current study was commissioned to provide a definitive statement on the issue of currency for the blind through a more exhaustive examination of options than had previously been undertaken. C. Methodology The study was conducted under the overall direction of a Steering Committee with representatives from the American Council of the Blind, the Federal Reserve System, and the U.S.Secret Service. A Working Group, which consisted of BEP technical, engraving, and printing specialists, performed background research and prepared the study. Two electronics consultants, one from the American Foundation for the Blind and one from the National Science Foundation, provided information on electronic currency reading machines. The study itself consisted of three portions: 1. The currencies of 54 foreign nations and the U. S. were reviewed for certain characteristics which would contribute to denominination discrimination by the sight impaired. Those countries which had purposely introduced intaglio, braille-like denomination symbols were then contacted. They were requested to provide information on the utility of the measures they had taken as well as to describe adverse effects encountered during production and circulation. Five countries responded to this inquiry. 2. The BEP working group then evaluated selected features on the basis of cost-effectiveness, probable usefulness to the sight impaired, and impact on the production of currency. 3. Finally, the concept of an automated portable currency reader was evaluated as an alternative, with or without any changes in the design of currency. Criteria used were production feasibility and cost to the consumer. II. EXECUTIVE SUMMARY, FINDINGS AND RECOMMENDATION A. Executive Summary There are two approaches which can be taken to provide assistance to the blind and visually handicapped for distinguishing different denominations of U.S. currency. These are the incorporation of certain features in the designs of Federal Reserve Notes and the development of portable electronic devices which will "read" and provide denomination information. The usefulness of these measures varies for different segments of the sight impaired population depending upon the degree of visual impairment. That population includes persons who have been blind since birth, those who were blinded later in life, and the partially sighted. This study is the result of the efforts of a group of technical specialists from the Bureau of Engraving and Printing (BEP), under the direction of a Steering Committee composed of representatives from the American Council of the Blind, the Federal Reserve System, and the U. S. Secret Service. The BEP working group assessed various mechanisms for denominating currency on the basis of cost-effectiveness, utility to the visually handicapped, and effect on production and circulation. The study findings are based upon a review of the currencies of 54 foreign nations, the experiences of countries currently producing currency for the blind, previous research performed by BEP, and findings by the American Foundation for the Blind. Several high potential mechanisms for denominating currency were identified: 1. Visual mechanisms, including intaglio colors, offset tints, and large, distinct numerals. The use of these visual devices would aid the partially sighted but would be of no benefit for the blind. Increased annual cost for currency for these modifications range from $640,000 to $3,500,000. 2 V Tactile mechanisms, such as braille-like symbols, clipped corners, and different sizes. Devices in this category could be of value to the blind as well as the partially sighted depending upon the device and the tactile skills of the target population. A design modification with high apparent utility for the blind and low counterfeitability is sized currency. This option would require BEP to expend about $26 million in implementation costs and would increase manufacturing costs by about $7 million per year. 3. Aural mechanisms, specifically an electronic "reader" to produce audible signals for different denominations. The working group determined that the development of a portable electronic currency reader should be encouraged whether or not actual changes to the design of currency are proposed. B. Findings and Recommendation CHAPTER III. IDENTIFICATION OF FEATURES TO AID THE VISUALLY HANDICAPPED Findings: III-1 There are three major categories of the sight handicapped, each with slightly different needs: Those born blind, those blinded later in life, and the partially sighted, III-2 Each of these groups has different skills to use in identifying the denomination of U. S. currency. III-3 A survey of 54 foreign nations indicated that the currencies of all these countries contain some features which may be of some benefit to the visually impaired population. However, few countries have intentionally designed currency for this purpose. III-4 None of the countries contacted indicated that the systems they were using for denomination of currency by the blind were completely satisfactory. III-5 Potentially useful design features are either visual (colors, large clear numerals) or tactile (braille or braille-like symbols, cut corners or notches, different sizes)• III-6 Electronic technology is presently available which can produce audible signals identifying bank note denominations. CHAPTER IV. ANALYSIS OF OPTIONS AVAILABLE TO THE UNITED STATES Findings: IV-1 A potentially effective method of providing currency denomination information to the sight-impaired is to develop hand-held, electronic currency readers. IV-2 Based on limited information, it would appear that the most widely useful currency design change would be to produce Federal Reserve notes in a different size for each denomination. However, the effects of such a change on broad and diverse segments of the population would be monumental. IV-3 Costs for making currency design changes range from $640,000 to $6,670,000 per year in addition to initial costs. Depending upon the design, as many as 150 additional Full-Time (personnel) Equivalents would be required by BEP to produce modified currency. IV-4 Changes to currency design and the issuance of new currency will probably have a significant impact on the public and private sectors especially on currency handling and processing equipment such as change machines. Recommendation: Pursue the development of and seek funding for a handheld electronic reader to denominate currency. IIJ. A. IDENTIFICATION OF FEATURES TO AID THE VISUALLY HANDICAPPED General In order to identify a range of features which should aid in the denomination of currency, the working group utilized a three stage process. First, the wtarget population11, or groups the denomination features would be designed to help, was identified. Next, the range of practicable options was examined through a review of 54 world currencies. Finally, the list of options for BEP analysis was determined, based upon the world currencies, BEP experience, and research into technological developments. B. Target Population There are actually three different categories of sight handicapped, each with different abilities which affect their needs for handling and denominating currency. These categories include: » 1. Persons who are born blind or who become blind in early childhood. They usually develop an excellent sense of touch and may have the ability to read braille. Currency with braille-like intaglio (line engraved, raised) printed symbols would assist this group. 2. Those who become blind later in life as a result of accident, disease, etc. and whose touch is typically no better than that of a sighted person of normal sensitivity. Raised or embossed symbols or braille markings (especially "jumbo" braille) might assist this group, although many do not read braille. 3. Individuals who are not totally blind but who have limited vision. These persons are usually able to distinguish bright, clear colors or large, simple numerals (also called Sanserif numerals). The sight handicapped "target population11 is therefore not a single entity, but a composite of individuals with disparate skill levels, many of whom are not able to read common braille or >raille-type symbols. To assure the broadest utility to the visually impaired, features would have to be selected which accomodate the abilities and needs of those who are blinded later in life and who may not have an especially acute sense of touch. C. Survey of Foreign Currencies A list of the currencies of 54 foreign nations was developed and the designs categorized by denomination (see Appendix 1). Factors considered as relevant were (differences in) note size, the location of key design features, color and depth of color, use of intaglio (or raised) printing, and inclusion of braille or braille-like elements. The braille elements could be produced in the currency paper, embossed on the notes, or intaglio printed. 1. There is a good deal of diversity among world currencies in terms of printing methods as well as design features. Some of the foreign currencies, such as those of Belgium, the Netherlands, and Israel intentionally, incorporate features to assist the sight handicapped. Other currencies contain mechanisms such as colors, which may, unintentionally assist the sight impaired. Of the 54 currencies reviewed, only that of the United States employs the same colors for all denominations. Other relevant currency characteristics which were identified include: a. Large, simple (sanserif) numerals for denomination - currencies of Ireland, Israel, and the Netherlands bear this type of numeral isolated from the surrounding design so as to be distinct and clearly legible. b. Different sizes for different denominations Twenty-nine of the countries employ a different size for each denomination. Nine other countries utilize sized notes for some, but not all, denominations. c. Braille symbols - None of the surveyed countries use braille or braille-like symbols which are embossed on the notes or are manufactured in the paper. However, Belgium, France, Ireland, Luxembourg, the Netherlands, Sri Lanka (Ceylon), and Switzerland issue currency with distinctive symbols imprinted by the intaglio process. 8 2. -Foreign experience with denomination features -The seven countries which utilize intaglio printed denomination symbols on their notes were contacted and asked for an assessment of their experiences* Five countries, Luxembourg, the Netherlands, Switzerland, Belgium, and Israel, responded. With the exception of Belgium, the respondents indicated that the symbols were of some utility to the blind* However, all of the Central Banks noted that the imprinted symbols were of limited durability* The Swiss found, through testing, that raised printing was generally ineffective after a few months - as soon as the bills lost their ff crispnessff. Switzerland also felt that different sizes of currency was potentially the most effective method of denomination. The Director of the Central Bank of Belgium indicated that while the utility of printed symbols to the blind was questionable, there seemed to be no obvious reason to eliminate the features, (as there seemed to be substantial drawbacks to other methods of tactile denomination). Durability of the printed symbols was also found to be a problem by the Belgians. 3. Selection of features for BEP Evaluation. Based upon previous research at the Bureau of Engraving and Printing and the review of, denomination features in foreign currencies, a list of potential devices for inclusion in U. S. currency was developed (figure 1). These were categorized by the means the visually handicapped would use to discriminate between different notes. The major categories include visual, tactile, and aural techniques. The category for audible signals, which would be produced by currency "readers", was included in recognition of recent advances in electronics technology which provide the capability to miniaturize commercially available devices. Chapter IV discusses the various options in more detail. D. FINDINGS. III-1 There are three major categories of the sight handicapped, each with slightly different needs: Those born blind, those blinded later in life, and the partially sighted. III-2 Each of these groups has different skills to use in identifying the denomination of U.S. currency. III-3 A survey of 54 foreign nations indicated that all the currency of these countries contain some features which may be of some benefit to the visually impaired population. However, few countries have intentionally designed currency for this purpose. III-4 None of the countries contacted indicated that the systems they were using for denomination of currency by the blind were completely satisfactory. III-5 Potentially useful design features are either visual (colors, large clear numerals) or tactile (braille or braille-like symbols, cut corners or notches or different sizes). III-6 Electronic technology is presently available which can produce audible signs identifying bank note denominations. 10 IV. A. ANALYSIS OF OPTIONS AVAILABLE TO THE UNITED STATES General This chapter presents the results of the BEP evaluation of selected features to assist the sight handicapped in denominating currency. Visual, tactile, and aural techniques are discussed in terms of cost, utility to the target population, and impact on production and circulation, B. Visual Mechanisms Persons of limited vision can often distinguish bright, clear colors of different hues as well as large, simple numbers. Color may be incorporated in currency in the intaglio printed image, in offset background tints (surface printing from photographically reproduced plates), or through tinting of the substrate (paper) during manufacture. To be of the most utility to persons of limited vision, the colors should be very distinctive, i.e. primary colors. Colors may, in addition, provide increased counterfeit deterrence value for currency. However, the optimum counterfeit deterrent currency requires more subtle coloration in order to make reproduction difficult. Such a configuration which might combine a dark, intaglio image with pastel offset background designs, would be of limited use to the sight handicapped. 1. The use of colored intaglio inks would require an initial cost of at least $470,000 and an annual increase in BEP costs of $640,000 ($.13 per 1000 Federal Reserve Notes). An additional 16 Full Time Employee Equivalents (FTEfs) would also be needed. 2. The introduction of offset (background) tints would cost at least $2,200,000 initially and $3,460,000 per year. As many as seventy-two more FTEfs would be required. 3. The manufacturing of currency with large, legible numerals would require a major design change and the preparation of new currency dies and printing plates. Any -costs would have to be weighed against the utility for only a small portion of the visually handicapped population. 11 C. Tactile Mechanisms Tactile mechanisms for the denomination of currency by the blind may be produced by modifications to either the substrate (paper) or the image (inks, etc.). Substrate modifications include different sizes (dimensions) for different denominationsj notched edges, clipped corners, or perforations; and embossed braille or braille-like symbols• Image modifications include intaglio printed braille-like symbols and braille-like symbols applied by a hot-melt or similar embossing procedure. 1. Research by the Central Bank of Switzerland indicates that different sizes of currency by denomination are most useful to the blind. No exceptional tactual acuity is required: a small template or coded ruler can be carried for use in comparing the dimensions of each banknote. There are several disadvantages to this approach, however. Inserting new denominations in a sized sequence would be extremely difficult. For example, introduction of a $2 bill between a sized $1 and $5 bill would have required substantial changes in the way BEP produced the notes as well as the handling by banks and private citizens. The current estimates of implementation costs at BEP for sized currency is $25,630,000, principally to acquire new processing equipment and to modify existing printing and processing equipment. Annual manufacturing requirements would increase costs by about $6,670,000 and would result in the need for 150 more Full-Time Equivalents. There would also be costs to the private sector for sized cash register drawers, modifications of automatic teller and change machines, etc. 2. Notched edges or clipped corners have frequently been suggested as a means for the tactile denomination of currency. However, of the foreign currencies reviewed, none exhibit this design feature, primarily because wear characteristics might invalidate the distinctiveness of notches or cut corners in a relatively short time. A similar mechanism would be the perforation of the substrate (paper) in a different pattern for each denomination. Greater tactual acuity would likely be required to recognize this device than to differentiate notched edges or clipped corners. Both of these design changes would necessitate additional capital equipment and staffing. The initial cost would be about $2,600,000. Annual costs would be $1,400,000 and require 29 Full-Time Equivalents. 12 _ 3* There are several methods of producing currency with braille or braille-like symbols. Traditional braille documents are produced by embossing a special, stiff paper to produce a series of raised dots in groups or "cells11 which designate letters or numerals. "Jumbo* braille is a larger, more widely spaced version of braille dots designed for those possessing a poorer sense of touch. For such embossing to be retained in a circulating banknote, the substrate would probably have to be thicker and stiffer than is typical of currency paper at present. A related option would be the manufacture of currency paper (substrate) with inherent (not embossed) patterns of raised dots. Such a substrate could be produced by selective deposition of extra fibers as a pattern of small lumps during the papermaking process. In this way, the overall substrate would not have to be unusually thick or stiff; in fact, the small lumps would be more easily discernable if the paper were rather thin and flexible. Alternatively, the process recently developed by the Minolta Corporation (Osaka, Japan) for the photocopying in relief of braille documents could be adapted to currency production: photosensitive microcapsules, included within the substrate, expand on selective exposure to long-wavelength illumination, creating a three-dimensional reproduction of the desired dot pattern in acceptable relief for braille. By this latter method of inherent substrate dot production, braille patterns could be generated after the banknotes are printed. Of the various features considered in this study, braille-like symbols which are printed by the intaglio method are the only design elements produced by any country solely to assist the blind. These elements are an integral part of the intaglio design, and are simply plate-printed as a component of the overall intaglio image. As reported by the Netherlands Bank, intaglio-printed identification marks are of optimal design when they are of the maximum height obtainable in plate printing (0.004 in) and the minimum width necessary to technically realize that height (0.020 in). However, because the relief achieved by intaglio printing is only one-fifth that of traditional braille, and because only a small proportion of the blind can read genuine braille characters, printed tactile identification marks usually consist of simple figures recognizable even at low relief. Symbols formed by narrow lines with an opening about a finger's width (0.400 in) between them, such as a square, circle, or triangle, have been found by 13 Dutch researchers to be the most easily recognized. The tactility of intaglio-printed identification marks can be enhanced by the design of such symbols using closely spaced (0.020 in) double lines, in order to reinforce the tactile effect. As an option, braille-like symbols or dot patterns could be applied to printed banknotes as a final stage in currency production using a hot-melt resin to create the desired design. In this way, the relief obtainable would likely be much greater than that achieved by intaglio printing. The adhesion of such an applied resin to the currency paper substrate would, however, need to be carefully evaluated. The utility of braille-like symbols for the blind is especially limited for these individuals who, because of age or infirmity, may lack necessary sensitivity or manipulative powers. Although intaglio printed braille-like symbols would be more easily discerned if the currency paper were rather thin, the height of the symbols will greatly increase the effective note thickness. This is also true for embossed or inherent symbols and means that process changes will have to be made in the handling and storage of notes. Costs to adapt current BEP equipment will be about $8,100,000. Annual costs will be about $3*050,000 with a requirement for 100 Full-Time Equivalents. There may be additional costs associated with redundant raw material inventories for dots imbedded in the paper substrate. Although Israel has encountered no problems with processing bank notes containing intaglio printed symbols through their bank's currency hand-ling equipment, no tests have been run with U.S. currency to determine the effect on change machines, etc. There is also some question as to the life of bills with braille markings. At the present time, $1 bills last about 18-22 months in circulation. The Federal Reserve System is attempting to upgrade the quality of currency which may significantly lower the circulation period. Adding braille dots may further lower the circulation time, requiring greater production and possible higher equipment expenditures at BEP. D. Aural mechanisms The development of a pocket-sized electronic reader, into which a banknote could be inserted and from which an audible signal would be emitted communicating the notefs denomination, is within the realm of currently available technology. Electronic denomination can be based on a number of different detection mechanisms, including recognition of images now present in currency. Features which could be incorporated in currency for instrumental detection are colors (intaglio or offset); bar codes, grids, or coded perforations; and threads of specific composition, shape, and/or location which would be embedded in the substrate. A desk-top size electronic denomination unit has already been successfully developed under the auspices of the American Foundation for the Blind. This machine, which is available through the Foundations Consumer Products Department, cost around $600.00. A successful reader which is portable has not yet become commercially available. A preliminary study sponsored by the Foundation (June 1, 1983) indicated that development of a miniaturized electric reader was feasible. Cost to consumers would range from about $75.00 to $250.00 depending upon sales volume. These estimates are tentative, but could be refined by the Foundation within 3 months through a more exhaustive analysis, funded at about $15,000. Research has been initiated by the Bank of Canada to evaluate electronic denomination of currency on the basis of recognition of the different colors employed in the present Canadian banknote issues. As an alternative, the Canadians have also proposed the electronic recognition of special grids (cross-hatching) of varying line densities which could be incorporated as localized design elements in an intaglio image. The Design Section of the Bureau of Engraving and Printing has developed a series of experimental Federal Reserve Notes with the oval border of the portrait area (obverse) redesigned to incorporate an unobtrusive bar code as part of the intaglio design. Such configurations might be refined to enable electronic denomination of 0. S. currency on the basis of bar code recognition. The incorporation of threads of special composition in currency paper would also provide a means of denomination. However, threads or bar codes would present only marginal advantages in electronic reading over recognition of intaglio characters now existing in notes. 15 E. Summary Each of the proposed design modifications presents some difficulties in regard to necessary changes to BEP production methods. Bach requires equipment changes and additions of personnel. There are also a number of not yet ascertained costs to the private sector for adaptation of currency handling, change making equipment, etc. The information which is available from foreign banks, however, would seem to indicate that more of the sight impaired population would benefit from different sizes of currency than any other method of denomination. The different notes could be easily distinguished through use of a small "template*. The implementation of this option, however, would have profound consequences for the public and private sectors in modifying currency handling equipment (cash registers, change machines) and issuance of new currency and redemption of replaced notes. Preliminary indications are that almost as broad a segment of the sight impaired population would benefit from use of an electronic device to audibly denominate bank notes as from sized currency. This option is considered as the second most useful option only because portable, affordable devices have not yet been commercially developed. Braille-like symbols would not be as useful for denomination as the sized currency and electronic scanner for three reasonsi many sight handicapped cannot read braille, the aged or those who are blinded later in life often do not have an extremely sensitive sense of touch, and braille symbols will likely wear down extremely rapidly in circulation. Notched edges or clipped corners on currency are anticipated to be of some utility. However, none of the foreign governments surveyed have employed this device in their currency. Because of this lack of experience with clipped corners and notches there is some concern about the effect of these techniques on currency wear charactistics, public perception of the modified notes, and usability of the notes in automated currency handling equipment. Additional problems may arise if notched currency is circulated without recalling presently circulating notes. Alteration of uncut notes could result in fraud and consequent nonutilization of the system by the target population. 16 Even though different colored notes are widely used by foreign governments, this technique would be useful only to those who have some vision. There would be no advantage to the blind. . F. Findings. IV-1 A potentially effective method of providing currency denomination information to the sight-impaired is to develop hand-held, elec-tronic currency readers. IV-2 Based upon limited information, it would appear that the most broadly useful currency design change would be to produce Federal Reserve notes in a different size for each denomination. However, the effects of such a change or broad and diverse segments of the population would be monumental. IV-3 Costs for making currency design changes range from $640,000 to $6,670,000 per year in addition to initial costs. Depending upon the design, as many as 150 additional FullTime (personnel) Equivalents would be required by BEP to produce modified currency. IV-4 Changes to currency design and issuance of new currency will have a significant impact on the public and private sectors, especially on currency handling and processing equipment such as change machines. G. Recommendation. Pursue the development of and seek funding for a handheld electronic reader to denominate currency. 17 V. SUMMARY Features which are selected for incorporation in currency to assist the jsight handicapped should be of utility to the widest segment of the population possible, have minimal impact on Bureau of Engraving and Printing production and public circulation, and be cost-effective. The BEP analysis indicates that there are a number of potentially useful design features which will assist various groups of the sight impaired• These include incorporation of visual cues for the partly sighted and tactile mechanisms for the blind. The potential also exists for developing low cost electronic units which will "read" the denomination of currency through the recognition of already existing intaglio designs. These devices will produce audible signals and would therefore be useful to almost all of the visually impaired. The only currency design feature which is generally as useful to the entire target population as an electronic reader is currency which is sized by denomination. There are several considerations which indicate that caution should be used in recommending any changes to the design of currency. The cost of the modifications which the Bureau reviewed range from $640,000 to $6,670,000 per year, in addition to one-time implementation costs of up to $25,630,000. These expenditures, however, represent only a portion of the true cost. The currency handling system comprises many segments, including retailers, banks, and private citizens. The industrial sector is also involved in currency changes as a result of capital expenditure and technological research to develop and manufacture cash registers, coin changers, automated teller machines, etc. These are also policy implecations related to a flnewlf currency. Currency is a tangible representation of the strength of Governmental institutions and the U. S. economy. Major changes or logistical problems associated with the distribution of bank notes may, at the worst, lead to some loss of public confidence or even temporary hoarding. Applicability of currency design modifications to the sight impaired population is also a complex question. Experience of the European nations which produce bank notes with features specifically included to assist the blind is rather limited. Tactile mechanisms such as braille-like 18 symbols meet the requirements of only a portion of the target group and are limited in terms of note durability. Colors would assist the partially sighted but not the blind* Electronic currency readers are now available but a commercial, low cost, easily portable version has not yet been developed. 19 Figure 1.

I found the tour through the printing works very interesting and I was very much impressed by the laboratorium. I enclose herewith a note we sent to the Bank of Canada on the intaglio marks for the blind as I promised. I also enclose a note of Dr. Koeze on the life-length of banknotes. An other trial is still on its way concerning the life-length of banknotes with regard to the machine direction in the papermill. I spoke about these trials with Mr. Seidel and Mr. Graminski. As soon as the report on the trial is there, I will send it to them. Would you please be so kind as to pass my gratitude to Mr. Seidel, Mr. Graminski and Mr. Heygster for the time they spent on me during my visit.

Bank of Canada Ottawa K1A 0G9 Canada Dear Mr. Freeth, Thank you very much for your letter of April 24, 198l, on identification of banknotes for the blind. As you know, we have used tactile symbols since the issue of our present f 10,banknote in January 1971* The experience we have gained since then is mixed. On the one hand, it is recognised in broad circles that tactile symbols may play a useful role for visually handicapped people. On the other hand, we feel that the present, rather gross form of our symbols is suboptimal. Smaller symbols might be recognized easier. Generally, one has to reckon with two categories of visually handicapped people. The first category includes persons born blind or become blind in the first years of their life. These people have an excellent feeling and have the ability even to feel and read the text and nummerals in intaglio on the front of our banknotes* For them special tactile symbols are not necessary. In our latest / 100,- banknote issued since March 16, 1981 we have improved upon the tactility of the text using letters without serifs and leaving out cadre lines etc. which hinder feeling. The letters are placed simply against a background in offset. The second category includes persons become blind later in their life, e.g. after a traffic incident. These people may be compared with others blindfolded. Their feeling is not exceptionally good, generally. For them special tactile symbols would be of a great help because they are not able to feel and read the text. It is this category at whom we aim our efforts. — • •— POSTBUS OB - 1OOO AB '•- • -•-• Amsterdam, Nay AMSTERDAM Mr. I.G. Freeth Canada - 2 Pure braille numbers are not effective, because only a small proportion of the visually handicapped are able to read braille. In aur country only about 4000 people out of 90.000 visually handicapped are familiar with braille. This is why we have chosen for a simplified system using the principle of braille. As you remark, pure braille dots have a height greater than the embossing which it is possible to achieve in intaglio. In the present form of our symbols we have compensated the lesser height by the greater-width of the dots. On afterthought, this appears a fallacy. A simple experiment is sufficient to show this as follows. If a sheet of normal writing paper (thickness about 0,1 mm comparable to the embossing on our banknotes) is laid flat on the smooth surface of a table, it is very well possible for people like you and me to feel the edges of the sheet. However, the even surface of the sheet is not recognizable. As shown above, people without visual handicap but blindfolded are representative of the category of handicapped people we aim at. So the conclusion is that it is not the actual height or the top of the intaglio point that is felt, but the discontinuity due to the height difference. Tactile symbols are optimal if they have the maximal height which can be achieved and the minimal width necessary for that height. The symbols should be spaced such that they can be felt one by one Typical dimensions of special tactile symbols are: height : 100 ^m width : 1 mm interspace: 5 mm Using this principle the tactile symbols of Switzerland, Belgium and other countries are better than ours. DE NEDERLANDSCHE BANK N.V. PO9TBUS OB - 1OOO AB Amsterdam, May 25, 1981 Mr. I.G. Freeth Canada AMSTERDAM - 3 - All countries have devised their symbols according to some sequential system, e.g. an increasing number of dots or lines. Obviously, it is difficult to insert a new denomination into the sequence. Recently, we have encountered this problem when we decided to design a f 50,- banknote which does not exist at present. It is more practical "to devise symbols using (simplified) numerals or (simplified) text. We are working along this line but our investigations have not yet come to a conclusion. Finally, we "have no information on how long the tactile feel remains useful in the circulation. .We hope that the information above is of any help to you. Taking this opportunity I should mention that Janus Ritter has retired in January and that Mr. J.R. Steinhauser has taken over his responsibilities.

LEUVER Director Department of the Treasury Bureau of Engraving and Printing W a s h i n g t o n , D.C. 20228 (U.S.A.) Concern: Incorporated design elements for blind. Dear Mr. Leuver, Referring to your l e t t e r of April 21st, 1983, I want to inform you that, as Luxembourg is linked to Belgium by an agreement on monetary association, belgian notes are legal tender and form therefore the greater part of luxemburgish circulation. Within the framework of this agreement, Luxembourg keeps i t s sovereign right to issue own notes, but has accepted limits as far as the amount and the denomination are concerned. As Luxembourg has no own engraving and printing center, our experience in the f i e l d of incorporated design elements for blind or visually impaired is very limited. Nevertheless, I think that intaglio printed design elements have a l e g i b i l i t y and an u t i l i t y to aid the blind in determining the denomination. Unfortunately, the durability is very limited because these marks are only perceptible as long as the notes are in new or rather good conditions. Sincerely yours, Brussels, 13th July, 1983. DIRECTION Dear Mr Leuver, Your letter dated April 21st, 1983 concerning the incorporation in banknotes of means by which the visually impaired might recognize them, only reached me recently. I heard that in the meantime you met Mr J. Van Droogenbroeck in Brussels and talked about this subject. So, I can only confirm our general impression about the use of intaglio printed signs : although the utility to the blind populatic of the elements as implemented in our notes is questionable, and the their durability is not what one should hope and the printing of th: deep intaglio engraving causes more frequent replacements of the packing material on our intaglio presses, we still see no obvious reason not to print those signs. Furthermore, the other existing ways of enabling people to distingui between different denominations of banknotes other than by sight (significantly different sizes, braille numbers or raised dot codes, clipped corners a.s.o) also have their specific drawbacks. We hope that in the future better printed intaglio signs wil fulfill this particular task more satisfactorily. If you need more technical details on this matter, please do not hesitate to get in touch with Mr J. Van Droogenbroeck. kind regards^/ / / Mr Robert J.Leuven, Director Department of the Treasury Bureau of Engraving & Printing WASHINGTON, B.C. 20228 (U.S.A.) 7N 1 V » p 3 1 BANK OF ISRAEL J"1- CURRENCY DEPARTMENT Jerusalem, July 4, 19B3 Dr. Edmond L. Graminsky, Chief Office of Research and Technical Services ; Department of the Treasury \mBureau of Engraving and Printing Washington, D.C. 20228 U. S. A. Dear Dr. Graminsky, Re: Mr. R.J. Leuver's letter dated April 21, 1983 regarding design elements for the blind In reference to Mr. R.J. Leuver's letter dated April 21, 1983, (which was received by us only on 14th inst.)we wish to inform you that we have not undertaken a special probe relating to the legibility and utility to the blind of the design elements incorporated in our banknotes for their benefit. As you may well know, we do not print our banknotes in Israel, but mostly in Holland. That is why we have originally adopted the system of the signs for the blind from the Dutch banknotes in coordination with the Dutch Central Bank. Filled signs were thought at the beginning to be the best element for sensitive touch but later, thanks to more investigations carried out by the Dutch and Belgian Central Banks, hollow geometric shapes were chosen for more recent banknotes as being a better element for the blind to feel. That is the reason a circle has been put on our latest banknote (the I.S.500). From the foregoing, it is obvious that we cannot point out if there were any detrimental effects in the production of the notes. Moreover, lacking automatic sorting systems, we are not in a position to report of any effects in the transport of the notes. Anyway, no problems were encountered in the passing of the notes through counting machines.

However, the Swiss National Bank (SNB) believes that to date no efficient banknote markiri9S have been found to benefit all types of blind people. A good differentiation method for the blind is still the different size of the individual banknote denominations. Therefore the SNB has encouraged the manufacture of templets to measure the different denominations. Following are some remarks concerning the experiences the SNB has had with the Swiss banknotes: - The selection of the markings was made by the associations for the blind at the time new banknotes (competition 1970) were created. - The selection of the markings presented few difficulties; the printing of the markings, however, was more problematic. Banknotes are subject to much greater wear and tear than, for example, books or newspapers in braille. - After the first few tests, the raised printing that was introduced at the time by the Netherlands and Israel was adopted. After a few months of circulation, a poll of the associations for the blind unfortunately revealed the inefficiency of the markings as soon as the banknotes lose their printing crispness. Further tests were not possible during that period due to lack of time and problems with design, printing and security. The creating of banknotes takes many years and must be prepared on a long-term basis. But we shall endeavor to find new ways to devise a code for the blind when we prepare the next series of banknotes. The associations for the blind request that the markings be retained and suggest o that the code be imprinted diagnonally on the front and back side c that more space be left between the dots and lines to facilitate reading o that thinner paper be used to achieve a greater sensitiveness of the code. However, the printing method which would assure the thickness and permanence of the markings is yet to be found. Perforated printing seems tc be out of the question for technical and security reasons. The addition of the code for the blind did not result in any additional costs to us because it formed an integral part of the copper printing plate when the new banknotes were niade. There are about 5,000 blind persons in Switzerland, and about 20,000 persons with impaired vision. This is approximately lto, respectively 3'^o of the total population In spite of this minority, there is a consensus of opinion that the problem should not be neglected.11 We trust this information will be useful to you. Should you have any further questions do not hesitate to write or to call us.

Schneider Executive Assistant Bureau of Engraving and Printing Department of the Treasury 14th & C Street, S.W. Washington, DC 20228 Dear Mr. Schneider: Enclosed is the feasibility study on techniques for generating a personal size paper money identifier to be used by blind and severely visually impaired persons. In a period of a few weeks, it is only possible for us to give you a rough estimate of cost, but we feel that they are probably accurate. If you require an extensive study and evaluation of the two techniques, to further refine the proposal and to get better information on the comparative advantages of the two techniques, I believe that it would require approximately three months of effort and $15,000 to get a more definitive evaluation. Specifications would have to be written and sent to a number of organizations, I hope this information is what you require and would be happy to give a presentation to Congress if you request it.

C 20036 (202) 467-5996 A POCKET CURRENCY READER FOR THE BLIND A feasibility Study* It is the purpose of this document to outline an approach for a pocket sized device for reading the denominations of paper currency. The primary purpose for the consideration of such a device, is an aid for the blind. It will be understood that the technology may also be applicable to a wide range of automatic processes where a definition of product or orientation may be desirable. However, we here limit the discussion to a currency reader for the blind in the United States. The basic technology is not new. Readers have been on the market for sorting currency for about fifteen years. These devices, however, have been enormously complex and expensive, compared to anything that could serve the individual blind person. More recently, however, a joint program between the American Foundation for the Blind and ARDAC, a company serving the note accepter field, has reduced the complexity of the earlier designs to the point that a new product keyed to the needs of the blind vendor has now been accepted by the Foundation, and is available through the Foundation's Consumer Products Department. In order to establish a reference for further discussion of the device here proposed, it is appropriate to discuss this device known as the paper money identifier for the blind. *T. Lynch, Ohio License E013319 The unit is pictured in Fig. 1. It operates from the normal power line. It accepts the notes in any geometric approach, and announces the denomination in clearly articulated English. It even tells the operator if the bill is of a preferred geometry (i.e., upside down). It "knows11 bills from all denominations from one to twenty dollars. Although the reading of the notes is a fairly sophisticated process, involving a pattern of forty to sixty indices, the unit is not particularly effective against sophisticated counterfeit notes. It will be understood that there is a great deal of technology involved in such discrimination, and a device claiming effectiveness in this discrimination yery quickly becomes expensive. Early studies by AFB concluded the marketability for the vendor aid will be severely limited if the retail unit cost of the device is much more than $600.00, and, consequently units were set that precluded engineering and development costs permitting for the rejection of counterfeit notes. Having described in the above paragraph what might be termed the state of the art, we now turn our attention to the description of this proposal. First, if $600.00 is a market problem for the blind vendor, even when assisted by the Randolph Sheppard Act, it is clear that a personal note reader must aim at a substantially lower figure if the market is to be large enough to support the device. It is probable, therefore, that a financially unassisted development effort of such a device will never happen, and therefore the purpose of this discussion is to provide a background for funding requests. INCQUCI I Ul UIIC U I I IIU--pflyC J A way to make substantial progress in this problem area of unit cost is to make the decision favoring sophisticated design and extensive tooling. This means the development of the device will be comparatively expensive, but the selling cost to the individual user will be moderate. It is impossible to estimate this figure with any degree of accuracy since production cost is sensitive to volume. In large volume (100,000 units) the cost of $75.00 seems reasonable and could increase to $250.00 with relatively low volume. We now turn our attention to the problems involved in going from the device of Fig. 1 to the pocket version. The major difference is that Fig. 1 handles the bill, moving it at a controlled rate of speed through the scanning mechanism. This is an expensive part of the machine, but it solves some tough problems. It cannot be a feature of a pocket device because of the cost but also because such a mechanism puts impossible demands upon the power available in a pocket device. Accordingly, the proposed device hypothicates a design where the scanning process is manually performed. The preferred embodyment is pictured in Fig. 2. The note is threaded sideways into the machine, and captured by a roller with an inertia brake. The operator, after loading the bill into the machine, pulls one end (either end), withdrawing the note and providing a mechanism for the scanning process. The inertia brake will control to an acceptable degree the regularity of the extraction process. The "reading11 of the note now becomes a simple extrapolation of the process in the vendor note reader. M rocKet Lurrency Keaaer tor the blind—page 4 It will be understood that a description of this reading process in detail will serve no one better than the potential counterfeiter/so we shall not reveal such details in this description. In fact, the vendor device does work; it has been approved by the American Foundation for the Blind, and since the scanning process and the logic are expected to be closely alike in the two machines, it is not in doubt that the pocket version of the device will have comparable performance. The vendor device for the blind announces the denomination of the note in plain English. This is an expensive feature. It is not yet clear that the price objective for the pocket version will permit this type of readout. It seems quite possible that a suitable investment in a speech synthesis chip specifically for the blind reader might reduce the per unit cost to an affordable figure. Should further study of the cost/performance ratio push the decision to a non-speech readout, pin-type readouts are available, and an acoustic readout comprising a keyed note or notes can be easily achieved. However, due to tactual discrimination problems for the elderly blind and blind diabetic may preclude this as an option. What we conceive, therefore, is the development of a pocket currency reader for the blind, similar in concept to the artist's sketch in Fig. 2, derived in its essential operating features from a currently available vendor note reader for the blind. uurrenty r^edaer Tor trie onna—page D A prototype, functional unit could be available in nine months. A marketable device from hard tooling, in eighteen months. The estimated cost for such a program is $250,000. Depending upon volume, price per unit from $75.00 to $250.00 seems feasible. The Bureau of Engraving and Printing has proposed a bar chart to be placed around the face on the bill. As I understand it, they propose a 12 mil spacing with 8 mil for a one and 4 mil for a zero. Each bit code would be utilized permitting error correction. This technique would probably cost the consumer approximately the same as the techniques described above. The reason that this seems likely is that the reduction in size of the computer algorithms in the microprocessor does not materially decrease the cost of the instrument. The microprocessor costs would possibly be reduced from $10.00 to $9.00. Because of the fine spacing on the bar chart, it does not seem likely that the optics would be substantially less complex than the existing optical system, and in fact, because of the close spacing might even be more expensive. Therefore, it seems that the bar chart approach would cost approximately the same as the approach suggested by ARDAC.

The results of both efforts confirm that special markings on currency would not be of any particular or lasting value to most blind people, due to the rapid wear of the raised symbols and the fact that the great preponderance of blind people lack the sensitivity of touch required to distinguish the markings. The latter situation arises because more than half of the legally blind persons in the United States are over the age of 60 and lost their sight at an older age. Even among younger sight-handicapped people, however, the tactile sensitivity required for reading Braille varies greatly from person to person and is not a universally acquired skill among the blind. In a survey, made by us in August 1977, of 22 organizations known to be concerned with various aspects of blindness, none responded in favor of special markings on currency to assist the blind. Moreover, the largest representative organization of blind people -- The National Federation of the Blind -- has actively opposed any legislation for Braille-type markings on U.S. currency. Therefore, because of the technical issues involved and because blind people themselves do not generally express the view that money handling is a major problem, we are no longer engaged in efforts to place raised markings on currency notes. Internationally, at the Third Pacific Rim Conference of Banknote Printers, held in Ottowa in September 1977, most member nations agreed that Brailletype currency has little real value to the blind and only serves as a "goodwill" gesture. This had been the finding of those nations who have experimented with this approach, and it seems highly unlikely at this time that many more nations will attempt to adapt their currencies in this manner.
