(Reuters) - How does 'mobile money' get in and out of a cell phone?
Systems vary in detail, but Nairobi resident Mary Wanjiku uses M-PESA, the continent's first such system set up by Kenyan mobile operator Safaricom, to send money to her mother in the countryside every month.
Here's what happens:
- Mary and her mother go to their nearest M-PESA agents with their official IDs and mobile phones to register themselves and their SIM cards on the system.
- Once she has activated her account and chosen a four-digit password, Mary charges up her account by giving the agent cash. The transaction and balance are confirmed via an SMS.
- Mary then transfers, via SMS, 3,000 Kenyan shillings ($38.40) to her mother's mobile phone account. M-PESA charges her a flat fee of 30 shillings.
- Her mother receives the SMS and keeps it on her phone until the local M-PESA agent passes through her village. She then transfers that money to the agent's phone via SMS, and the agent gives her the cash. Her mother is charged 45 shillings, a fee proportionate to the size of the withdrawal.
- Mary can also send money to friends who have not registered for M-PESA or who use a different phone network. In these cases, the fees at both ends of the transfer are higher.
