(I didn't see a new thread, so continuing here.)So basically we can expect all TouchID devices to support it from here on in, since they have the hardware crypto needed. It's likely even iPad will get that technology in the next generation. I'll split the Apple Pay chat out into a separate thread, since it's completely distinct from the graphics side of things
I'm surprised that they're using BLE for this. My experience with Bluetooth and BLE is one of painful discovery and/or pairing. Not suitable at all for the kind of instant communication that's needed for payment process that Apple showed in its video. It wouldn't surprise me if BLE does work for Apple Pay, but not as smooth as with NFC. At that point, it becomes more of a checkmark feature that won't be used much.
