Security remains a paramount concern in both residential and office settings, prompting the exploration of various solutions. Existing door lock systems often exhibit vulnerabilities that compromise security, raising apprehensions about a safe lifestyle and conducive work environment. Moreover, contemporary challenges, such as terrorism and unauthorized access, underscore the urgency of implementing robust security measures, especially in shared-access spaces. This paper introduces the design and prototype of a biometric fingerprint door lock system tailored for joint access environments. Fingerprint biometrics, known for their reliability, offer a secure means to log system transactions and safeguard individual privacy rights. In contrast to RFID or password-based mechanisms susceptible to compromise, the proposed system relies solely on fingerprint verification, providing enhanced security for shared facilities. The system, built on an Arduino UNO platform, incorporates a fingerprint sensor, camera, servo motor, buzzer, and an LCD display. Authorized users’ fingerprints are enrolled and verified, granting access to shared facilities, while centralized control facilitates user management. This flexible device ensures physical security by leveraging fingerprint sensor technology.
