问题
Main Question:
If I were to start developing a mobile peer-to-peer payment app (Namely on iOS and Android), where would I start? i.e. What APIs would I use to create transactions that can occur between to peers, using debit and/or credit cards?
What are the recommended languages for a backend?
My take:
From the research I have done, it would seem that companies like Square Cash etc. made use of the MasterCard and VISA APIs. This is possible something I would have to use.
I would also make use of Java as the backend, to then make use of these APIs to allow P2P payments between two peers by means of stored (Obviously encrypted) credit or debit card details.
Am I on the right track? Any suggestions from experts?
