Until today millions of WhatsApp users in Africa cannot do transactions through WhatsApp, I would like to create a WhatsApp payments platform that will enable them to do so,by linking their visa/MasterCard then do transactions,the app might be separate from WhatsApp but instantly sends feedback through WhatsApp messenger, and one initiates the payment through WhatsApp. This will enable users to pretty much do everything while in WhatsApp platform. One idea is to use mobile money numbers which are also used in WhatsApp as accounts then integrate them within this payments app to facilitate an easy transaction. The app itself can be used as a registration place and a transaction facilitator. All in all one should be able to do the transaction while chatting in WhatsApp.
