In a coup for Kenya, the M-pesa mobile money transfer (mFinance?) system offered by Safaricom has now become the first mobile international money transfer service. This is amazing news for Kenyans, and for everyone else, too. Right now my bank charges me $30 to wire money internationally. I have no doubt that the charges for M-pesa are going to be a LOT lower -- and that this kind of innovation and competition will help us all.

Terrific leader in the Economist and longer "special report" about mobile financial systems like Kenya's M-PESA, which are transforming the way people save, use, and transport money in poor countries.
