In reply to Philip Cohen.

I think we agree-- Apple doesn't care about payment per se--only about making it easier to do more activities using Apple devices. Commerce is clearly moving to mobile devices, and payments is integral to commerce, so Apple will integrate existing payment rails into what they offer and count on what else they bring-- trust, good user experience, high spending customers--to get merchants on board.

If adding a different payment method will help with adoption, Apple might incorporate it, but they have zero interest in displacing V/MC/AXP.
