The Bioteknix INBIO-260 PRO PLUS is an IP-based biometric access control system designed to manage and secure entry points using multiple authentication methods. The system integrates hardware and software to verify identities through fingerprints, RFID cards, passwords, and dynamic QR codes. Its architecture supports two doors with real-time monitoring and event logging, enabling centralized management over TCP/IP and RS-485 networks. The system stores a large number of user credentials, ensuring scalability for offices, factories, and residential complexes. Advanced security features such as AES-256 encryption, HTTPS/TLS 1.2 communication, and anti-passback ensure protection against unauthorized access and data breaches. By combining identification, authentication, and controlled access, the INBIO-260 PRO PLUS demonstrates modern access control theory, emphasizing automation, reliability, and secure data management in multi-user environments.
