Tips How do you use NFC?

http://androidforums.com – I bought some NFC tags yesterday and I have been playing with them since then. I really bought them out of curiosity and because they were cheap. So far the only use I have thought of is to enable my phone to recognise when it is in my cheap desk dock (I could have achieved something similar with a soldering iron, a bunch of resistors and a bit of time but this was easier). This led me to wonder what everyone else (at least those who use NFC) was using NFC for? (General)
