I just ordered some small RFID stickers and a USB RFID reader/writer. Planning to put the stickers on albums, and to have the reader near the stereo, and adding a little code to play the album on the jukebox when waved nearby.
Let me know if you have done something like this.
Update: I got the PN533 usb stick today, and have hacked together a little script to handle it. So far I am simply using a UID to Album mapping, it would be nice to put the barcode, artist and album title into the tag!
And I need a USB extension cord, so the place you have to wave the album isn't very awkward to reach. And I need to put stickers on albums and fill in the mapping.
