Who is doing it: Kenyan telecom provider Safaricom offers \n\nthe M-Pesa mobile money transfer service to its 12 million subscribers. Shopkeepers, banks \n\nor other business owners can register as agents who accept deposits, dispense cash or use \n\ntheir phones to debit customers' accounts. For example, Mama Wanja, a business owner who \n\nruns a shop in central Kenya's Thika district, extends credit to customers and debits their \n\nM-Pesa accounts when it's time for them to pay their bills.\nMore on CIO.com\nVodafone and Western Union to Partner on Money Transfers\n\nMobile Phone Banking Poised for Growth in Africa\n\nHow it works: Individuals or financial institutions can send money \n\nelectronically to M-Pesa or make cash deposits through an agent. Safaricom charges a \n\ncommission for transfers based on the amount of the transaction, but a deposit is free. The \n\ncommission is then divided between Safaricom and the agents. There are five million \n\nregistered M-Pesa users; individuals who are not registered can still use the service, but \n\npay more for it. \n\nGrowth Potential: Too early to tell. In its first six months (ending last \n\nSeptember), M-Pesa had yet to break even. John Kamau, general manager of NetLink Limited, a \n\nretailer of mobile devices and services, thinks fees for the service will drop and the \n\nmarket will expand once other mobile providers in Kenya launch their own money transfer \n\nservices.
