M-Pesa founders on launching Kenya's mobile wallet

Susie Lonie and Nick Hughes are the people responsible for Kenya's M-Pesa mobile money transfer system.

It allows people without bank accounts to transfer money quickly, easily and safely using their mobile phones, and has radically altered developing world economies.

There are now nearly 100 similar systems in the developing world.

The pair recently picked up an Economist Innovation award for the service.

The BBC's Fiona Graham spoke to them about launching M-Pesa, how businesses have benefited from the service, and dowries.
