The main innovation I like is NFC in the Watch. This makes so much sense. What is the big advantage of pulling a phone from your bag instead of a wallet? Paying with a wrist, opening doors with your wrist, entering the metro with your wrist. Can't wait for the next Wear releases from Samsung to have it integrated :)

Sony Smartwatch 3 has NFC (and GPS). Too bad it's rather ugly. AFAIK, it only currently uses NFC for pairing to a phone, but the hardware is there and Android Wear will hopefully soon include complete support for it, like they recently did with watch GPS support.

Unfortunately it is only a passive tag for pairing. You can't to do anything else with it, so it cannot read other tags itself.

No touch ID though, that's still on the phone so.... I'm guessing payments won't be as useful on the watch, if present at all.

Yeah, I was wondering about this. My guess is that security will be based on the fact that you wear a watch, so it's much harder to lose it or steal it. Maybe they will have a passcode that applies until you take the watch off (which they have the sensors to detect). Maybe it will confirm proximity to your phone. There are possibilities.
