I created a little device I've wanted for a while that uses the ESP8266 to read NFC/RFID tags and when it gets one, sends it to an HTTP URL. Using this, I can do all sorts of cool home automation stuff like play a music album or youtube video that I can associate with an NFC tag.
The whole thing is open source and open hardware and you can check it out here: https://github.com/happy-bubbles/nfc
Right now it's simple enough to just wire together with a NodeMCU board and an RC522 cheapo RFID module, but if people like this I could design a PCB to make it look nicer.
Anyway, maybe this is useful to someone else too.
