The main goal of this paper is to design and implement a multilayer security system, which can be used in bank, secured offices and homes. The system is based on RFID, Keypad and a fingerprint scanner technology containing door-locking system, which can activate, authenticate, and validate the user and unlock the door in real time. This system consists of microcontroller, RFID reader, Fingerprint scanner, keypad locker, and display module. The RFID reader reads the id number from passive RFID tag and send to the microcontroller, if the id number is valid then the user will be asked to enter the keypad password and after the password is verified the user will be asked to use the fingerprint scanner which will match the fingerprint and if user gives a wrong input then alarm will be generated and a blue tooth connection will be established with an android device which will take a picture of the unauthorized person. After completing all the security check successfully, the locker system will be accessible to the user and the system will be prevented from any unauthorized access.
