I just picked up the NFC/RFID breakout from Adafruit. As soon as I finish up another project, I’d like to take a look at how it could be used with the Imp. I see that there is a library for using it with with the Raspberry Pi, so clearly it isn’t going to be trivial. Has anyone done any work with this?

What NFC/RFID board did you pick up? We’ve had success with various RFID boards… there might be some overlap.

I got the PN532 breakout.
I am thinking about mounting it in my front door and having it control the deadbolt.

It looks like it’s SPI, UART, or I2C to communicate with it - so that’s handy!
