This project has implemented two layered security architecture using micro-controller. Primary/first layer of security will implement user authentication system using smart RFID card. The list of authorized RFID’s will be kept as a database in a micro-controller memory. After user is successfully authenticated, the magnetic door will automatically open and close. Magnetic door is equipped with the magnetic switch to provide alarm in case of RFID security is breached. Project will implement alarm notification using the combination of both buzzer/sound and lightening/blinking the LED’s.
