A multifunctional design that supports independent fingerprint registration, fingerprint comparison, and fingerprint search. The compact design is portable, energy-efficient, and features a universal interface with high reliability and ease of operation. Scalable capacity for 1:N identification (up to 5,000 fingerprints, non-modular identification, response time under 2.5 seconds). Easily integrated into systems to create customized fingerprint identification solutions. During the identification process, once a fingerprint feature is successfully recognized, it is stored in the database, enhancing user convenience over time. Features automatic correction and identification: place a registered finger on the module at any angle, and comparison is completed seamlessly. Low false acceptance rate: up to 0.0001%. Low false rejection rate: up to 0.0001%. Suitable for use in access control systems, attendance machines, storage cabinets, locks, security devices, terminals, medical management systems, intelligent monitoring equipment, and more.
