USB Biometric Fingerprint Scanner for Access Control Attendance Management

Multifunctional design that supports independent fingerprint registration, comparison, and search. Compact and portable with low power consumption, universal interface, and high reliability. Scalable capacity for 1:N identification with up to 5,000 fingerprints, non-modular identification, and response time under 2.5 seconds. Integrates into systems to meet customer requirements for fingerprint identification solutions. During the identification process, once a fingerprint feature is successfully recognized, it is stored in the database for improved user experience over time. Features automatic correction and identification—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%. Compatible with access control systems, attendance machines, storage cabinets, fingerprint locks, security devices, terminals, hospital management systems, intelligent monitoring equipment, and more.
