m-Pesa relies on a network of small shop-front retailers, who register to be m-Pesa agents. Customers come to these retailers and pay them cash in exchange for loading virtual credit onto their phone, known as e-float. E-float can be swapped and transferred between mobile users with a simple text message and a system of codes. The recipient of e-float takes her mobile phone into her nearest retailer when she wants to cash in, and swaps her text message code back for physical money. There are already more m-Pesa agents in Kenya than there are bank branches. (via The Invisible Bank: How Kenya Has Beaten the World in Mobile Money – News Watch)
