April 15th, 2008 RFID Security System
Designed to replace the antiquated mechanical push button locks on doors, this easy-to-use security system is built around the embedded RFID tags in student ID cards. Of-course any other RFID enabled card could be used, with modification to the source-code.
The system can store codes from up to 20 different ID cards in the ATmega32’s EEPROM but if you need a larger storing capacity an external EEPROM memory can be inserted with adjustments in the schematic and source code. I think its cool how things evolve, and instead of building an access system based on password, you can easily build this RFID system.
