Two processes are involved in fingerprint processing: fingerprint registration and fingerprint matching. Fingerprint matching can be performed in two ways: fingerprint comparison and fingerprint search. The fingerprint module is a built-in fingerprint processing module that integrates the optical path and processing functions, featuring small size, low power consumption, and simple operation. The fingerprint algorithm extracts features from the fingerprint and displays the fingerprint information. Storage, comparison and search of fingerprints are handled by operating fingerprint functions. Key benefits - Enables reliable enrollment and fast verification through two-stage matching (comparison and search). - Compact, integrated design with low power consumption for embedded applications. - Efficient feature extraction and straightforward display of fingerprint information. - High reliability, fast detection, robust performance with wet or dry fingers, and quick search results. Use scenarios - Access control terminals for doors and gates in offices or facilities. - Time attendance systems to log employee presence with quick verification. - Secure user authentication in kiosks and self-service devices.
