Bank locker security demands highly reliable and tamper-proof authentication mechanisms due to increasing theft attempts, unauthorized access, and cyber-physical intrusions. Traditional locker systems rely on a single level of authentication—such as a physical key or PIN—which is susceptible to duplication, hacking, or brute force attacks. This research proposes an IoT-enabled three-layer security system for bank lockers that integrates RFID authentication, biometric verification (fingerprint/face recognition), and OTP-based access control transmitted through secure IoT platforms. Additional features include real-time intrusion detection using sensors and automatic alert generation to bank authorities and customers. The system leverages microcontrollers such as ESP32 or Raspberry Pi for network connectivity, cloud synchronization, and data logging. By implementing multi-level authentication, the security of bank lockers is significantly enhanced, reducing the risk of unauthorized access. The proposed model is cost-effective, scalable, and future-ready for integration with smart banking environments. Results demonstrate improved security reliability, greater user accountability, and rapid response mechanisms.
