A multifunctional design that supports independent fingerprint registration, comparison, and search. Compact and portable with low power consumption, universal interface, and high reliability, it is easy to operate. Scalable capacity for 1:N identification with up to 5,000 fingerprints, non-modular identification, and response time under 2.5 seconds. Easily integrates into systems to meet customer requirements for fingerprint identification solutions. During the identification process, once a fingerprint feature is successfully recognized, it is securely stored in the database for improved user experience over time. Features automatic correction and identification—simply press a registered finger on the module at any angle to complete comparison. 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, fingerprint locks, security devices, terminals, hospital management systems, intelligent monitoring equipment, and more.
