Abstract

In today’s world, the security of bank lockers is paramount due to increasing instances of theft and unauthorized access. This project addresses the challenge of enhancing locker security by developing a Multi-level Secure Bank Locker System. The system integrates several advanced technologies, including RFID for user authentication, a sound sensor to detect tampering attempts, and a SIM800L GSM module for real-time alert notification Additionally, a fingerprint sensor is used to ensure biometric security, while a keypad matrix allows for PIN verification, further safeguarding access. The novelty of the system lies in its multi-layered security approach that combines hardware components and communication technologies. The ESP32 Micro-controller serves as the central processing unit, managing data flow and communication between the modules. In case of unauthorized access or tampering, the system triggers a buzzer for an immediate alarm and sends an alert via SMS to the owner’s registered mobile number or Telegram app. Initial tests of the system demonstrated its robustness in preventing unauthorized access and responding effectively to tampering attempts. The results highlight the practicality of employing multiple security layers, which significantly improves the reliability and safety of traditional bank lockers.
