Managing hundreds or thousands of employees in a factory environment requires accurate attendance tracking, efficient workforce scheduling, and reliable security management. Traditional attendance methods such as paper records, ID cards, or manual check-in processes often create problems including time theft, buddy punching, inaccurate records, and complicated payroll management. A biometric attendance system for factory management provides a smarter solution by using unique biological characteristics such as fingerprints, facial features, and palm vein patterns to verify employee identities. With advanced biometric technology, factories can improve attendance accuracy, reduce administrative workload, and build a more efficient workforce management

With the rapid development of digital services, organizations worldwide are facing increasing challenges in identity verification. Traditional authentication methods such as passwords, ID cards, and fingerprint recognition may not always provide the required level of security, convenience, and flexibility for modern applications. As a result, businesses and governments are increasingly adopting advanced biometric technologies to improve identity management. Among different biometric methods, palm vein recognition technology has gained significant attention due to its high accuracy, contactless operation, and strong security performance. A mobile handheld palm vein recognition solution combines advanced biometric authentication with portable hardware, allowing
