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 compatible with 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 compatible with fingerprint identification solutions. During the identification process, once a fingerprint feature is successfully recognized, it is securely stored in the database compatible with 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 compatible with use in access control systems, attendance machines, storage cabinets, fingerprint locks, security devices, terminals, hospital management systems, intelligent monitoring equipment, and more.
