A versatile design capable of independently completing fingerprint registration, comparison, and search. Its compact and wearable design features low power consumption, a universal interface, and high reliability, making it easy to use. Scalable Capacity 1: N Identification (5000 fingerprints, non-modular identification, response time less than 2.5 seconds). Can be integrated into systems to form fingerprint identification products that meet customer needs. During the fingerprint identification process, after a newly captured fingerprint value is identified, it is merged into the fingerprint database, allowing users to utilize it more conveniently over time. Automatic Correction and Identification Function: Press the correctly registered finger at any angle onto the module, and the comparison can be completed. Low False Acceptance Rate (FAR): up to 0.0001%. Low False Rejection Rate (FRR): up to 0.0001%. Used for fingerprint access control machines, fingerprint search, fingerprint attendance machines, fingerprint storage cabinets, one-click automatic driving, fingerprint writing, fingerprint locks, fingerprint security, fingerprint terminals, fingerprint management, intelligent monitoring equipment, etc. Specification: Condition CPU: 144 MHz Main Frequency: 1M Flash Bit, 128KB for SRAM Fingerprint Scanner: Capacitive Fingerprint Size: 192X192 (pixels), 508 DPI Fingerprint Registration Capacity: 1000 by default, expandable to 5000 Identification Rate (FAR): Less than 0.001% Deviation Percentage (FRR): Less than 0.1% Fingerprint Size: 570 bytes Security Level: Level 1 to Level 5. Default is Level 3 Processing Speed: Fingerprint extraction time Less than 0.45 seconds Communication Interface: UART, 3.3V-TTL level or USB connection Serial Communication Parameters: Parity = None; Stop Bit = 1 Flow Control = None Baud Rate: 9600, 19200, 38400, 57600, 115200 baud Operating Voltage: DC 3.3V ± 10% Working Current: Less than 30mA, fingerprint peak current less than 80mA (momentary current) Idle Current: Less than 10uA Working Environment Protection: Operating Temperature: -10°C - 60°C Relative Humidity: 20% - 80% Color: Black Material: Plastic Size: Approx. 6.5 x 3.8 x 1.7 cm Package Contents: 1* Fingerprint Registration Module Only the above package content is included; other products are not. Note: Light reflections and different displays may cause the color of the item in the picture to differ slightly from the real object. The allowable measurement error is +/- 1-3 cm.
