This biometric USB fingerprint scanner is a compact and reliable module designed for secure access control, attendance tracking, and identity verification. It features a high-precision capacitive sensor with 360-degree automatic correction, allowing for quick recognition from any angle. The device supports a large fingerprint database, expandable up to 5000 templates, with a rapid response time of under 2.5 seconds for 1:N identification. Engineered for low power consumption and easy integration, it offers exceptional accuracy with a false acceptance rate (FAR) of less than 0.001% and a false rejection rate (FRR) under 0.1%. The module provides adjustable security levels and communicates via UART (3.3V TTL) or USB interfaces. Its durable plastic housing and compact size make it suitable for a wide range of applications, including time clocks, secure cabinets, POS systems, smart locks, and hospital management.
