HOW TO – Homemade RFID reader

Doug writes – “For our final project, we designed and built (and exhaustively tested) an RFID-based proximity security system for use with Cornell Identification cards, which have been RFID-embedded since fall of 2003. The idea for this project was sort of spawned from our general interest in RFID technologies and the near-simultaneous occurance of Lab 2 (Keypad Security System) and the antiquated lock system at our fraternity house breaking.” – Link.
