Compact built-in fingerprint processing module with integrated optical path and on-board fingerprint processing. Key benefits On-board fingerprint algorithm extracts fingerprint features and displays fingerprint information, so the module handles core biometric processing without heavy host-side computation. Integrated storage, comparison, and search functions allow reliable fingerprint registration and matching workflows (matching supports both direct comparison and broader search). USB and UART communication make the module straightforward to connect to a wide range of host devices and embedded systems. Compact size and low power consumption reduce space and energy requirements for products that incorporate the module. Simple implementation reduces development time when adding biometric authentication. Core functions Feature extraction: the module extracts fingerprint functions (minutiae/features) and provides fingerprint information output. Storage & management: templates and fingerprint data are stored and managed by the module’s internal functions. Matching modes: supports a registration process and a matching process; matching can be performed as direct comparison (one-to-one) or as a search across stored templates (one-to-many). Interfaces: communicates via USB and UART for command, control, and data exchange. Integration: a built-in solution that integrates optical paths and fingerprint processing parts, with characteristics of low volume, low power consumption and simple. Compatibility and integration notes Connects to hosts over USB or UART; suitable for embedded controllers, microcontrollers, single-board computers, and PC-based systems that support these interfaces. Because extraction, storage, comparison and search are performed on-module, host software only needs to send commands and receive results, simplifying integration and reducing host workload. Typical applications Access control: door entry systems and turnstiles that require compact, low-power biometric authentication. Time and attendance: employee clock-in/out terminals where reliable registration and fast matching are required. Embedded device authentication: secure login for kiosks, point-of-sale terminals, industrial controllers, and other embedded equipment where space and power are constrained. Technical highlights Built-in fingerprint processing module with integrated optical path and processing components. Supports full fingerprint lifecycle: registration, storage, one-to-one comparison, and one-to-many search. USB and UART interfaces for flexible connectivity. Designed for low volume and low power consumption and simple.
