Mobile payment platforms have largely failed to alter consumer spending habits. Most platforms fall into categories like mobile banking, remote purchases, person-to-person payments, and point-of-sale payments. For mobile payments to succeed, all players in the value chain must work to create easy-to-use interfaces and show customers clear benefits. However, each group faces challenges in seeing revenue opportunities or reducing costs enough to justify changing existing behaviors. Technologies like near-field communication (NFC) and SMS could enable mobile payments, but issues around security, interoperability and high implementation costs remain barriers.
