Some people have already speculated that a successful global rollout of WhatsApp payments could quickly kill most of the existing local peer-to-peer mobile payments solutions. For example, in Finland and Sweden (which both are small countries but quite advanced when it comes to mobile payments) most people use Swish, MobilePay, or Siirto. Each solution is backed by a bank (or a group of banks) and each have their limitations. WhatsApp, however, is used by almost everybody and it’s relatively easy to see how it could quickly become the preferred platform for sending money.
