Mobile top-up for international remittances:
New opportunities and new risks
October 5, 2009
The growth in the mobile telecommunication industry worldwide is driving the
ubiquity of handsets, which in turn is expanding the reach of financial services
across wireless networks in less developed countries.

Adding air-time value (industry parlance known as "mobile top-up") to a mobile
phone represents a new method that some mobile network operators (MNOs) are
using to provide payment services, particularly in emerging countries where
financial services are scarce. One example is Safaricom's M-Pesa, offered in Kenya
and Tanzania. This service uses money agents, often small village stores, to sell
additional air time on mobile phones. This air time can then be used for nontelecom
purchases of goods and services, or sent via text message (SMS) as a person-toperson (P2P) payment transfer, allowing the recipient to use the prepaid value.
A recent case study found improved financial access in years following the 2007
launch of M-Pesa. The availability of mobile payment services lessened the
population's reliance upon more risky hand-to-hand transfers and has been widely
reported as a positive development for these emerging economies. Initiatives such
as the Mobile Money for the Unbanked (MMU) program supported in part by the
Bill and Melinda Gates Foundation, are contributing to the expanded use of mobile
financial services in emerging markets.
Mobile top-up is also emerging as a means for international remittances by
allowing users in one country, such as the United States, to purchase mobile air
time for users in other countries, thereby "topping-up" the recipient's account in the
local currency. For example, Western Union recently announced a service to

provide mobile top-up remittances within the United States for users of phones
issued by LIME in the Caribbean. Because many international telecom operators
have roaming agreements that span geographic borders, mobile top-up remittances
can be far-reaching, with the recipient using the prepaid value on the mobile phone
to purchase goods and services in the home country.
While these innovations have been shown to have positive impacts in terms of
access to financial services in emerging markets and may offer a number of other
efficiency benefits, they also alter the risk profile for service providers and those
who monitor payments for criminal activity. Depending upon the business model
and parties involved, regulatory and law enforcement agencies will have new issues
to consider in terms of anti-money laundering and monitoring international
payment flows under existing laws. These developments in the mobile top-up
market deserve continued attention to ensure that effective policing of payment
flows can ride alongside the positive developments in the emergence of a new
means for movement of money internationally.
