Ask HN: Anyone working on NFC technology ?

I'm curious if anyone on Hackernews is working around NFC (Near Field Communication )/contactless technology. I don't see many posts about NFC, which it's quite surprising because that's a pretty fun technology to hack around.

I interned at a startup where they were betting on NFC's rapid growth, but it isn't happening yet. I'd like to know your thoughts about NFC's possible future.
