A couple of weeks ago, Ignacio Mas from the Bill and Melinda Gates Foundation wrote a guest post on the topic of interoperability of mobile money.   At this year’s Mobile Money for the Unbanked Working Group in Barcelona, he also gave a very interesting presentation on the subject. In this video he takes an in depth look at the subject and discusses how operators can work together to add most value to users. He answers question such as, should operators interconnect their platforms to create any-to-any payment possibilities for their end-users? Should they offer common payment interfaces to bulk users, so that utilities, employers and the government don’t have to negotiate with and integrate into each mobile money scheme separately?
