ZKTeco inBIO controllers are designed for flexibility and scalability. Available in 1-door, 2-door, and 4-door models, they can be mixed to optimize system architecture and reduce costs. Each controller supports up to 3,000 fingerprint templates, 30,000 card users, and stores up to 100,000 events and transactions with real-time SD card backup to prevent data loss. Key features include Anti-Passback, First-Card Opening, Multi-Card Opening, Duress Password Entry, and programmable auxiliary input/output linkages.

Firmware can be upgraded in the field, and the free SDK allows integrators and OEMs to customize inBio controllers for existing security or personnel management systems. Even if network connectivity is lost, inBio continues to operate independently, ensuring uninterrupted security.
