I'll let you in on a little secret - paywave/paypass etc are EMV cards. The interface is wireless and they have a shorter transaction flow. There are less (zero) customer validation techniques, final evaluation (pass/fail) takes place at the stage a 'normal' EMV transaction would decide on pass/online/fail.

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!

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?

I'm in the UK, and had a NFC "smart tag" on the phone I threw away a year ago. Never bothered getting a new tag for my new phone. Maybe when I next upgrade my phone and get one with built in NFC.
