Since the "Super Secret Key" (used to create pub/private pairs) is 256 bit we should be able to store it in the Ring as well.

I would like a mobile wallet that will not send out BTC without an extra 'unlock' from my ring.

hopefuly if my phone gets stolen the nfc lock is some protection but an extra layer on getting money out sounds good to me.

There is a nice FAQ on payment protocols with BTC on the bitcointalk forums.

Some talk about Bluetooth but NFC yet.

I would like a tap to unlock wallet at least
