Android Wear: Capitaine Train on your wrist

Maybe you can do something similar to replace boarding passes for airlines? Many airlines these days allow you to do a web checkin at home etc.
Anyway, this reminded me that a friend created an app for Google Glass to show nearby transit options (trains/trams/buses etc) and their departure times.

So glasses vs watches?
To be honest, lets pick an arbitrary future date (eg: 5, 10, etc years from now) what type wearable tech would we be wearing?
I haven't seen it on Android Wear yet, but Norwegian (low cost airline in Scandinavia) has that on their (iPhone) app. The app is pretty much only that actually: you can't use it to buy, but you can check-in, see gate information and have a QR boarding pass.
Actually, the apps of most companies that I've used in the past year (Air France, Luftansa, Finnair) offer the same.
I must admit, I've been impressed with Android Wear so far. I was cynical but decided to get one to play with, and even just having notifications on the wrist comes in handy in so many situations for doing quick triage (while driving, while in a situation where pulling out a phone would be rude, etc). Displaying a QR code on the screen to get on a train (or even plane) is a great idea, and it might not even be long before they can do contactless payments with NFC..
I think we're still in the early days of this stuff (the Diamond Rio age prior to the iPod being released, if you will) but I see a lot of promise here.
