don’t take off your tinfoil hats quite yet, but just when you thought rfid tags were all about the man wanting to track you, somebody has come up with a more positive application.
dividuum figured that since some rfid tags can store a kilobyte of data, he should be able to gzip a sid audio file and squeeze it onto one of these larger tags. he then wrote some software for his pc that interfaces with an rfid reader and will play the sid file contained in a nearby tag. put a stack of cards next to the reader and it will cycle through them like a playlist.
follow the link if you want to download the source or check out a video of it in action.
