A great article about the elements of the design of Safaricom’s tremendously successful M-PESA service in Kenya.
“In Kenya, sending and receiving money with a mobile phone is not an intuitive idea for many people. It is important, therefore, that communications around how the service works and how it benefits users be simple and clear. From its inception, M-PESA has been presented to the public as offering a simple service—“send money home.” This basic remittance product has become the must-have “killer” applica- tion that continues to drive service take-up. M-PESA’s marketing campaigns have worked well; most Kenyans queried know that M-PESA can be used for money transfers.”
