A multifunctional design that can independently complete the collection of fingerprints, registration of fingerprints, fingerprint comparison and fingerprint search;The compact design is convenient to carry and store, it has low power consumption, universal interface and high reliability, it is also easy to operate. Scalable large capacity 1: N identification (5000 fingerprints, non-modular identification, response time less than 2.5 seconds). It can be easily integrated into the user system to form a fingerprint identification product to meet customer needs;In the fingerprint identification process, after the recently retrieved fingerprint characteristic value is successfully recognized, the characteristic value is melted in the fingerprint database, so that users can use it more and more easily. 360 degrees Automatic correction and identification function, press the correctly registered finger at any angle on the module, and the comparison can be completed;Low level of false fingerprints: up to 0.0001%, low rejection of fingerprints: up to 0.0001%. It is used for fingerprint access control machine, fingerprint root search, fingerprint attendance machine, fingerprint storage cabinet, one-click autorun, fingerprint printing, fingerprint lock, fingerprint security, fingerprint POS terminal fingerprint, fingerprint management hospital cover, intelligent monitoring equipment, etc. Specification: Condition CPU: 144 MHz Main Frequency: 1M Flash Bit, 128KB for SRAM Fingerprint Reader: Capacitor Collection Fingerprint Size: 192X192 (pixels), 508 dpi Fingerprint registration capacity: 1000 by default, which can be increased to 5000 Fake Identification Rate (Far) Less than 0.001% Deviation Percentage (fRR) Less than 0.1% Fingerprint size: 570 bytes Security level settings: from level 1 tolevel 5. The default value is Level 3 Processing speed: fingerprint extraction time Less than 0
