Claire Adida and Jennifer Burney of the University of California, San Diego, in the U.S. are developing a mobile money platform to enable the rural poor in West Africa to pay school fees directly and securely using mobile phones to help more children stay in school. Mobile money is not widely used in West Africa and many individuals do not use banks. Often money for things like school fees has to be physically transferred over long distances, which is unreliable and takes time. Recording payments is done largely by hand, which is error-prone and difficult to track.
