The main advantage of using passive RFID and GSM is more secure than other systems.

We have implemented a bank locker security system based on RFID and GSM technology containing door locking system using RFID and GSM which can activate, authenticate, and validate the user and unlock the door in real time for bank locker secure access. In this system only authentic person can be recovered money from bank locker. The main goal of this paper is to design and implement a bank locker security system based on RFID and GSM technology which can be organized in bank, secured offices and homes. At completion, the system quite responded in the four set modes: it adds/deletes user fingerprints appropriately, shuts-off when instructed, opens/closes the door when a registered fingerprint is recognized, displays messages appropriately on the LCD screen and receives/sends the appropriate SMS to the Administrator’s phone. The microcontroller’s code is written in ASSEMBLY language using KEIL MICRO-VISION3 emulator/debugger. The microcontroller polls the SMS received by the GSM modem, interprets it to puts the system in the desired mode, sends appropriate SCAN/DELETE/ADD command to the fingerprint scanner, opens/closes the door at each access request by any user (registered or not) based on the present system mode and command it receives from the scanner. The main components are a Fingerprint Module, a GSM/GPRS modem, the door & its control circuitry, and an AT89C52 microcontroller. The administrator phone sends SMS commands to the system to put it in the desired operating modes (as security situations arise) and to add/remove users of the premise thus, the system can work both independently and as dictated by the administrator. In this design a biometric (fingerprint based) access control system was developed with added versatility: remotely Adding/Removing users and monitoring the system’s operation via a GSM Phone. Access control systems restrict access to a secured premise or other secured devices (like a safe) only to authorized persons.
