This multi-functional design independently completes fingerprint registration, fingerprint comparison, and fingerprint searching. Convenient to carry and use, it features low power consumption, a universal interface, and high reliability, making it easy to operate. Scalable capacity for 1:N identification (5000 fingerprints, non-modular identification, response time less than 2.5 seconds). It can be integrated into systems to create a fingerprint identification product that meets customer needs. During fingerprint identification, after the latest extracted fingerprint characteristic value is successfully identified, the characteristic value is merged into the fingerprint database, allowing users to use it more and more effectively. Automatic correction and identification function: press the correctly registered finger at any angle on the module, and the comparison can be completed. Low false acceptance rate: up to 0.0001%; low rejection rate: up to 0.0001%. It is used for fingerprint access control machines, fingerprint searches, fingerprint attendance machines, fingerprint storage cabinets, one-click autorun, fingerprint writing, fingerprint locks, fingerprint security, fingerprint terminal fingerprint, fingerprint management hospital protection, intelligent monitoring equipment, etc. Specification: CPU: 144 MHz Main frequency: 1M Flash Bit, 128KB for SRAM Fingerprint reader: Capacitor Fingerprint size: 192X192 (pixels), 508 Fingerprint registration capacity: 1000 by default, which can be increased to 5000 Identification rate (FRR) Less than 0.001% Deviation percentage (fRR) Less than 0.1% Fingerprint size: 570 bytes Security level: from level 1 to level 5. The default 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 Transfer rate: 9600, 19200, 38400, 57600, 115200 ( Operating voltage: DC 3.3 V 10% Working current: less than 30 mA, and the maximum value for fingerprints is less than 80 mA (instantaneous current) Inactivity current: Less than 10uA Working environment protection: Operating temperature: -10 Celsius -60 Celsius Relative humidity: 20% -80% Color: 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 to be slightly different from the real thing. The allowable measurement error is +/- 1-3 cm.
