Does anyone here have experience with the adafruit pn532 or libnfc? The libnfc wiki has lots of good ideas and half baked solutions...

I'd like to take input from the card and use the UID to query a backend database and display arbitrary information on a website. Any advice or pointers would be useful.

Background: I have the pn532 completely working with LibNFC on a raspberry pi. I just suck at coding.
