Usage Tips: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 , it has low power consumption, universal interface and high reliability, it is also easy to operate.Scalable capacity 1: N identification (5000 fingerprints, non-modular identification, response time less than 2.5 seconds).It can be easily integrated into the system to form a fingerprint identification product to 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. Automatic correction and identification function, press the correctly registered finger at any on the module, and the comparison can be completed;Low level of fingerprints: up to 0.0001%, low rejection of fingerprints: up to 0.0001%.It is used for fingerprint access control machine, fingerprint search, fingerprint attendance machine, fingerprint storage cabinet, one-click autorun, fingerprint printing, fingerprint lock, fingerprint security, fingerprint terminal fingerprint, fingerprint management hospital cover, intelligent monitoring equipment, etc.Specification:Condition CPU: 144 MHzMain Frequency: 1M Flash Bit, 128KB for SRAMFingerprint Reader: Capacitor CollectionFingerprint Size: 192X192 (pixels), 508 Fingerprint registration capacity: 1000 by default, which can be increased to 5000 Identification Rate () Less than 0.001%Deviation Percentage (fRR) Less than 0.1%Fingerprint size: 570 bytesSecurity level settings: from level 1 tolevel 5. The default value is Level 3Processing speed: fingerprint extraction time Less than 0.45 secondsCommunication Interface: UART, level 3.3 V-TTL or usb connectionSerial Communication parameters:Parity = No; 1 stop bit = 1 Control = NoneTransmission 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 10uAWorking Environmental Protection:Operating Temperature: -10 Celsius -60 CelsiusRelative humidity: 20% -80%Colour:blackMaterial:plasticSize:about 6.5 x 3.8 x 1.7cmPackage Contents:1*Fingerprint registerOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
