Feature:1. Hold Many Fingerprints: Fingerprint scanner can hold 10 fingerprints, set fingerprints for multiple accounts, set fingerprints for each family member using a separate account, and automatically log in to their own accounts through fingerprints.2. 360 Degree Auto Calibration: 360 degree auto calibration and recognition function, press the correctly registered finger at any angle on the module to complete the comparison.3. Multifunctional: Multi functional design, fingerprint collection, fingerprint registration, fingerprint matching and fingerprint search can be done independently.4. Wide Application: Mini fingerprint reader is used for fingerprint access control machine, fingerprint root search, fingerprint attendance machine, fingerprint storage cabinet, one touch automatic operation, fingerprint printing, fingerprint lock, fingerprint security.5. Compact Structure: Computer fingerprint reader is compact, easy to carry and store, low power consumption, universal interface, high reliability and easy to operate.Specification:Item Type: Fingerprint Key ReaderMaterial: ABSCPU: 144Hz main frequency, 1M Bits Flash Memory, 128KB SRAMFingerprint Capture: Capacitive captureFingerprint Image Size: 192 x 192 (pixel), 508 DPIFingerprint Registration Capacity: 10 by default, expandable to 5000False Acceptance Rate (FAR): <0.001% (Security Level 3)Rejection Rate (FRR): <0.1% (Security Level 3)Matching Method: 1:N and 1:1 matchingFingerprint Template Size: 570 bytes ByteSecurity Level Setting: Level 1 to Level 5 configurable, factory set value: Level 3Processing Speed:Fingerprint Feature Extraction Time <0.45 seconds1:N matching time (for 3000 full registrations) <1.5 secondsCommunication Interface: UART, 3.3V-TTL level or USB communicationSerial Communication Parameters:No Parity Parity = NONE, 1 stop bit Stop Bit = 1No Flow Control = NONEBaud rate of 9600, 19200, 38400, 57600, 115200 (bps)Factory Setting: 115200bpsOperating Voltage: vin voltage: DC3.3V10%Operating Current: less than 30mA, peak less than 80mA (instantaneous current) when collecting fingerprintsSleeping Current: less than 10uA working environmentOperating Temperature: -10-60.Package List:1 x Fingerprint Key Reader
