Nokia Lumia 920 and 820 Hit AT&T Stores November 9

They work great, at least for Android devices. I don't see why they wouldn't work with WP8 though. I use about four of them daily (by the bed, at the entrance to my home, in the car and at work). I don't use Samsung's app for reading them as it was very limited last I tried it. I've heard its gotten much better, but I've still been using NFC Task Launcher to great affect.

As long as the Windows App Store has some sort of similar app to utilize NFC, I highly recommend using them. They're very convenient.
