Abstract
Safeguarding digital and physical premises against unauthorized entry is increasingly crucial in an era characterized by fast technological advancements and escalating security risks. Biometric security devices for controlling entry employ distinct form and behavioral attributes to authenticate persons and regulate access, hence offering innovative solutions. This paper offers a comprehensive review of the utilization of fingerprint recognition methods in the creation of an entry authorization device with biometrics. The material and methods section provides a detailed description of the hardware components used, including the Arduino UNO and fingerprint scanner module (SM 630), as well as an in-depth explanation of the construction process and performance evaluation. The text provides detailed explanations of the registration and operating methods, specifically emphasizing the gathering of biometric information, generation of templates, user registration, and the decision-making processes for controlling entry. This paper advocates for the utilization of fingerprint authentication for access control technology as crucial tool for improving safety and mitigating risks in different operational environments. It recommends a systematic approach that involves preparation, construction, testing, deployment, and future planning.
