The Digital Dawg Pound has a created a RFID Front Door Lock that uses inexpensive off the shelf electronics. There is a full listing of all the parts required on their site. “The project works as follows: When a card is placed in front of the RFID reader it outputs a TTL serial signal representing the card’s unique ID.
