A compact, built-in fingerprint processing module with integrated optical path and processing unit designed for reliable, fast biometric enrollment and identification. Key benefits Secure and reliable authentication: supports fingerprint registration and robust matching to prevent unauthorized access. Fast response and search: quick detection and rapid fingerprint search speed reduce wait times in high-traffic environments. Works with real users: good adaptability to both wet and dry fingers improves recognition in varying conditions. Easy integration: small size and low power consumption suit embedded systems and devices where space and energy are limited. Flexible connectivity: USB and UART interfaces allow connection to PCs, microcontrollers, access controllers, and other host systems. Core functions Fingerprint registration: capture and store fingerprint templates during enrollment. Fingerprint matching: supports two matching modes — direct fingerprint comparison (one-to-one) and fingerprint search (one-to-many). Performance and attributes Built-in optical path and processing module: combines sensor optics and processing circuitry in a single unit for simpler system design. Low volume and low power: compact footprint and energy-efficient operation for embedded or portable applications. High reliability and fast detection: tuned for dependable captures and rapid verification. Good adaptability to wet and dry fingers: reduces false rejects and improves user experience in varied conditions. Communication: supports both USB and UART protocols for broad compatibility with host devices. Typical applications Door access control and security panels: fast, reliable authentication for entry systems in offices, facilities, or secure rooms. Time and attendance terminals: quick enrollment and high-speed identification for workforce management. Embedded systems and peripherals: integrate biometric authentication into kiosks, POS terminals, industrial controllers, or custom hardware using USB or UART. Why this module solves common problems Reduces integration complexity by providing a self-contained optical sensor and processing unit. Minimizes user friction with fast matching and tolerance for wet or dry fingers. Fits into space- and power-constrained designs while offering standard USB and UART connectivity for straightforward host integration.
