I feel like the Coin card that's coming out in 2014 could be disruptive and part of the "future of credit cards". As someone with 7-8 cards that bulk up my wallet, the chance to have all of those housed in one smart credit card is exciting.

I don't know how I feel about using my phone as a primary payment method, and others must feel the same, since NFC payments have failed to take off (at least so far).
