The fingerprint algorithm extracts features from the fingerprint and displays fingerprint information. Storage, comparison, and search of fingerprints are performed by dedicated fingerprint functions. The fingerprint module is a built-in processing module that integrates optical paths and fingerprint processing components. It is compact, low power, and simple to integrate. High reliability, fast detection speed, good adaptability to wet and dry fingers, and fast fingerprint search speed. Fingerprint processing involves two processes: fingerprint registration and fingerprint matching. Fingerprint matching can be performed by either fingerprint comparison or fingerprint search. Use scenarios - Access control for buildings or rooms, and employee time attendance in offices. - Secure login for devices or terminals in industrial settings. - Verification in self-service kiosks or visitor management systems.
