In an interview in Fortune with Amex CEO Ken Chenault he states that it will be five platforms that matters in the future of payments; Apple, Amazon, Facebook, Google, and Alibaba. Of course American Express will be embedded in each of these.

Comment: I believe local/regional platforms beside “the big 5” will take/have a great part in future payments. Also interesting is the Amex founding that $25 trillion spent out there is outside credit/debit cards, most on peer-to-peer payments. Hard as of today for Amex to take part in this, eg. interchange fee challenge..
