A Universal RFID Key via HaD. drj113 writes –

A while ago, I was looking at Hack A Day, and I saw an amazing project that somebody had made.  It was an RFID card with a keypad on it.  For the next couple of days, I couldn’t get the image of the card out of my mind;  the project reminded me of how much I wanted to build a RFID spoofer myself.  The original author didn’t release source code for their project, but they left enough clues that I could follow. 

So, in typical fashion,  I built my own reader hardware so I could have a look at the data from a card, and created my own version of the Universal RFID key.

The key I made works beautifully both on my garage door, as well as on my office door!

  1. Now all i can hope for is a kit released by the adafruit team.

  2. I wonder what happened to the ‘B’ button.

  3. Congratulation !
    It’s not so difficult to build, it’s difficult to program !

    Can you share with us (who don’t have a instructable pro account) the pdf file ?
