MFRC522 RFID Support?

I have the MFRC522 RFID reader (with correct cards) that I’d like to use with Mopidy.

I played with a different install and was able to get the reader working with a series of python scripts using VLC however I am stuck getting Spotify to work with that system.

I setup the latest Mopidy and quickly got Spotify working, however I’m having a hard time getting the MFRC522 to work.

Has anybody used that reader?
