Financial inclusion spurs economic development, and digital mobile devices are considered an efficient tool for incorporating an unbanked population into the financial market. Despite this, close to 2 billion adults worldwide remain unbanked, as business models of digital financial services for the bottom of the pyramid have not proliferated. This article argues that the state may play a crucial role: acting as a catalyst to advance financial inclusion of the poor. We analyze how a conditional cash transfer (CCT) program may be an effective platform to achieve this. We offer evidence and analyze a pilot project through which beneficiaries of the CCT program in Mexico (Prospera) were migrated from a system of cash transfers to the use of digital transfers. The results show that a digital transfer platform may indeed be effective if governments integrate diverse public entities into the mobile money ecosystem and if they promote market competition in service delivery.
