Question that I didn't hear addressed anywhere in the talk or online yet. Will the NFC capability be exposed to third party apps through the SDK in any way? I'm curious because they started talking about the apps for iWatch right after talking about its features, but they didn't discuss NFC in any other context but its use via Apple Pay. What do you all think?
