Why have the coin with "contactless" payment (as paywave etc is known in the uk at least) when the phone itself should be capable of that itself.
I wonder why the big US banks aren't on board with driving contacless NFC payments?
Commonwealth Bank, the largest bank in Australia is very soon releasing native Android NFC support and NFC style "smart tags" that you stick to the back of your iPhone.

This pretty much eliminates the need for any kind of "card aggregation". I wonder how quickly other countries will follow suite?
As usual there are variations between implementations, but underneath it's all good-ol' EMV :)
So I doubt that these could be supported easily by Coin, it requires various keys that the banks do not allow to escape.
If Coin do manage to get talking to banks about allowing wired or wireless EMV apps to be loaded onto a customer Coin card then that would be awesome. I predict that layers of bureaucracy and brand-management will prevent this.
But good luck to 'em if they try!
