Built-in optical fingerprint module with integrated processing, designed for reliable, fast fingerprint capture and matching in embedded and PC-connected systems. Key benefits Fast, accurate detection: quick fingerprint acquisition and rapid search speed reduce user wait time and improve throughput. Works with wet and dry fingers: good adaptability to different finger conditions lowers enrollment and recognition failures. On-board processing reduces host load: the module handles fingerprint registration and matching internally, simplifying system design. Compact and low power: small footprint and low power consumption suit space- and energy-constrained devices. Functions and performance Two-step fingerprint processing: registration (enroll new fingerprints) and matching (verify or identify). Matching modes: supports one-to-one comparison and one-to-many search to handle verification and identification workflows. Integrated optical path and processing unit: optics and fingerprint processing are combined in a single module for consistent image capture and efficient template extraction. Interfaces and compatibility USB and UART communication: standard interfaces make it easy to connect to PCs, microcontrollers, embedded controllers, access panels, or gateways. Host-agnostic operation: internal processing minimizes driver or compute requirements on the host system; compatible with systems that support USB or UART peripherals. Form factor and power Low volume design: compact module integrates necessary optics and processing hardware to save board space. Low power consumption: suitable for battery-powered and always-on devices where energy efficiency matters. Practical applications Access control and door security: use for employee or resident identification in turnstiles, door controllers, and electronic locks. Time and attendance systems: reliable enrollment and fast identification to streamline punch-in/out for staff. Embedded consumer and industrial devices: integrate into POS terminals, kiosks, control panels, or handheld units that require secure biometric identification. Why this module solves common problems Reduces false rejections during real-world use by adapting to wet and dry fingers. Simplifies integration by performing enrollment and matching on-board and offering USB/UART interfaces. Saves space and power compared with solutions that require external processing or larger optical assemblies. Included functions (as specified) Fingerprint registration process for creating templates. Fingerprint matching process with both comparison (1:1) and search (1:N) modes. Built-in fingerprint processing module that integrates optical paths and processing components. Communication via USB and UART. If you need a compact, energy-efficient fingerprint module with internal processing, robust performance with wet/dry fingers, and standard USB or UART connectivity, this module is suited for access control, attendance, and embedded identification applications.
