This document discusses how transport systems can help ignite e-money and mobile money adoption in emerging markets. It argues that making transport a central part of e-money solutions systematically leads to ignition by reaching the broadest customer base and becoming a top spending category. For ignition to be successful, solutions need compelling value propositions for all participants, sustainable business models, and planned network effects. They also benefit from open technology standards that encourage collaboration between transport operators, mobile networks, banks and other ecosystems. Emerging markets have found successful approaches to digital inclusion through transport-focused applications that combine mobile services, and established lessons can be learned from their innovations.
