A multifunctional design that can independently complete 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 0.45 seconds Communication Interface: UART, level 3.3 V-TTL or usb connection Serial Communication parameters: Parity = No; 1 stop bit = 1 Flow Control = None Transmission Speed: 9600, 19200, 38400, 57600, 115200 ( Operating voltage: DC 3.3 V 10% Working current: less than 30 mA, and the maximum value of fingerprint collection is less than 80 mA (instantaneous current) Inactivity Current: Less than 10uA Working Environmental Protection: Operating Temperature: -10 Celsius -60 Celsius Relative humidity: 20% -80% Colour:black Material:plastic Size:about 6.5 x 3.8 x 1.7cm Package Contents: 1*Fingerprint register Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
