A multifunctional design that can independently complete fingerprint collection, fingerprint registration, fingerprint comparison, and fingerprint search. Its compact design is convenient to carry and features low power consumption, a universal interface, and high reliability, making it easy to use. Scalable capacity for 1:N identification (5000 fingerprints, non-modular identification, response time less than 2.5 seconds). It can be easily integrated into your system to form a fingerprint identification product according to customer needs. During the fingerprint identification process, after the characteristic value of the newly acquired fingerprint is successfully identified, the characteristic value is merged into the fingerprint database, allowing users to use it more and more easily. Features automatic correction and identification; simply press a correctly registered finger anywhere on the module to complete the comparison. Low false acceptance rate (FAR): up to 0.0001%, low false rejection rate (FRR): up to 0.0001%. Ideal for fingerprint access control machines, fingerprint search, fingerprint attendance machines, fingerprint cabinets, one-click autorun, fingerprint writing, fingerprint locks, fingerprint security, fingerprint terminals, fingerprint management for hospital security, intelligent monitoring equipment, etc. Specifications: Condition CPU: 144 MHz Main Frequency: 1M Flash Bit, 128KB for SRAM Fingerprint Reader: Capacitive collection Fingerprint Size: 192X192 (pixels), 508 DPI Fingerprint Registration Capacity: 1000 as standard, expandable to 5000 Identification Rate (FAR): Less than 0.001% False Rejection Rate (FRR): Less than 0.1% Fingerprint Template Size: 570 bytes Security Level Settings: Level 1 to Level 5.
