C

With smart phones taking the world by Storm,a phone that Can only send and receive voice

calls and text messages may seem like a relic from a bygone age.Yet in East Africa,simple

phones like these are changing the face of the economy,thanks to the mobile money services that are spreading across the region.

Usilng the text-messaging function built into the GSM system(全球通)used by most cell

phone networks,these services allow people without a bank account or credit card to use their

phone as an electronic walletthat can be used to store.send or receive cash.

It works like this:you pay cash to your local agent who then tops up your mobile money

account using a secure form of text messaging.That money can be transferred(转账)to another

person by sending a message to their cell phone account.

For some the system is a lifeline.“If I didn,t have my mobile phone.1 would be very

poor,”says Neyasse Neemur,a mother of four children who lives in northern Kenya.“Now I

can sell fish.”

Neemur took up fishing in July last year,but making money from it was a little tricky,

especially as Turkana people do not usually eat fish.A truck from Ethiopia to Tanzania passes

through her village once a week,and she arranged to have the driver transport the fish several

hundred kilometres south to market in Kisumu.where relatives sell the fish.

“I get the money transfer immediately.”says Neemur.“Then I can pay for my children to go to school and for vegetables and beans,”she adds,“so I don’t need to eat fish.”

According to the Central Bank of Kenya,payments worth around l billion Kenyan shillings

($13 million)per day were transferred through Kenya,s mobile money systems in 2009,equalling

the country,s credit card transactions(业务).The bank expects mobile money transfers to overtake credit cards in 2010.
