NESIT Hackerspace in Meriden, CT, is building a RFID-equipped security system to secure the space.

Starting the project I needed to figure out how to interface a RFID reader with the Pi. I wanted to interface it with the UART pins but due to time constraints I ended up using a sparkfun USB adapter with my Innovations ID-20 RFID reader. The only thing I has to do was monitor the USB in /dev and receive the RFID tag ID when someone scanned their card. To do this I used python script that monitored serial connection on /dev/ttyUSB0 the base of the script which I have posted to my github account and used a sqlite3 database to verify if the card scanned was a valid member, if so it would trigger the door. Also used a RGB LED to notify if the card was good or not.

    I think the RFID scanner (and the screen) should be the only things sticking from the wall, the other parts beeing inside the room.
    Else you could crack open the box, cut a few wires and make contact ala McGuyver or use the SD card in your own RasPi to see how the system works and force it open every 10 seconds depending on how the system communicates with the doors.
