Dear All,
I had bought a Parallax RFID reader and 2 transponders. I think the transponders are blank as I cannot read anything from the card. I am using a Arduino Uno with the code posted on Arduino Playground

Anyone have any idea how can I write to the 2 transponder cards so that I can read and do my coding. Must I buy another reader? What are the module that is compartable with Parallax? I hope I can just used the reader to write to the card. Is it possible? Since it says reader dont think can write.
Any advise? Thanks a lot
