A32 Optical Fingerprint Reader USB Biometric Modular Scanner Access Control Sensor for Windows<;;;br/><;;;br/>Feature:<;;;br/>1. Process of fingerprint identification, the newly extracted fingerprint feature value is successfully identified and then merged into the fingerprint database, so that the user can use it in the process as better as possible.<;;;br/>2. 360¡Æ automatic correction and recognition, press the correctly registered finger at any angle on the module, the pair is successful, and you can pass.<;;;br/>3. The fingerprint recognition rate is low, the maximum is 0.001%, and the false rejection rate (FRR) is less than 0.001%.<;;;br/>4. USB model, supports up to 1000 fingerprint users. The fingerprint window adopts waterproof technology.<;;;br/>5. Support the full range of windows. Support the secondary development of for Android platform. Communication interface includes UART, 3.3VTTL level or USB communication.<;;;br/>Specification:<;;;br/><;;;br/>Item Type: Optical Fingerprint Reader<;;;br/>Material: ABS<;;;br/>Main Frequency: 120MHz<;;;br/>Flash Memory: 1M Bits<;;;br/>SRAM: 128KB<;;;br/>Fingerprint Collector: Optical acquisition<;;;br/>Fingerprint Image Size: 640 x 480(pixel), 508DPI<;;;br/>Fingerprint Registration Capacity: 1000 PCS by default<;;;br/>Fake Recognition Rate (FAR): <;;; 0.001%<;;;br/>Rejection Rate (FRR): <;;; 0.001%<;;;br/>Comparison Method:1 : N and 1 : 1 comparison<;;;br/>Fingerprint Template Size: 570 bytes<;;;br/>Safety Level Setting: Level 1 to Level 5 can be set<;;;br/>Factory Setting Value:Level 3<;;;br/>Communication Interface: UART, 3.3V-TTL level or USB communication<;;;br/>Serial Communication Parameter<;;;br/>Parity None: 1PC Stop Bit<;;;br/>Baud Rate: 9600, 19200, 38400, 57600, 115200(BPS)<;;;br/>Factory Setting: 115200BPS<;;;br/>Operating Voltage DC 3.3V ¡¾ 10%<;;;br/>Pin Functions:<;;;br/>RST: Reset module, low level is active<;;;br/>VIN: Main power supply of fingerprint module, 3.3V by default<;;;br/>Power Ground: GND<;;;br/>RX: Module receives data pins<;;;br/>TX: Module sends data pins<;;;br/>Finger Detection Function Circuit Power Supply: 3.3V<;;;br/>Wakeup: Finger detection function outputs pin, outputs high level when a finger is pressed on<;;;br/><;;;br/>Package List:<;;;br/>1 x Optical Fingerprint Reader<;;;br/>1 x USB Cable<;;;br/>Note:<;;;br/>Professional use, do not understand this knowledge, please choose carefully.
