Key benefits Reliable fingerprint recognition with fast detection and search speeds to minimize user wait time and reduce authentication bottlenecks. Robust performance on both wet and dry fingers, improving real-world usability and reducing false rejects. Simple integration and data handling: the module extracts fingerprint features, displays fingerprint information, and supports storage, comparison, and search operations through built-in fingerprint functions. Flexible connectivity via USB and UART for straightforward connection to PCs, microcontrollers, and embedded controllers. Core functions and how they solve problems Fingerprint feature extraction: the onboard algorithm converts raw impressions into stored fingerprint data, enabling accurate comparison without exposing raw images. Registration and matching workflows: Registration process: capture and store fingerprint templates for each user. Matching process: supports two modes — direct fingerprint comparison (one-to-one) and fingerprint search (one-to-many) — allowing both verification and identification use cases. Template storage, comparison, and search are managed by the module’s fingerprint functions, offloading processing from the host and simplifying system design. Compatibility and performance Communication interfaces: supports USB and UART, making the module compatible with a wide range of host devices and development platforms that support serial or USB communications. Performance attributes: high reliability, fast detection, and fast search speeds ensure consistent operation in access control, attendance, and authentication systems. For physical specifications (size, mounting, materials) and electrical requirements, refer to the product datasheet or technical manual provided with the module. Practical applications Access control: integrate into door controllers and secure entry points to provide fast, reliable user authentication without passwords or cards. Time and attendance systems: enable rapid fingerprint-based clock-in/out to reduce queuing and simplify payroll management. Device and system authentication: add biometric login to kiosks, terminals, or embedded devices where USB or UART connectivity is available. What to expect from integration Reduced development effort: built-in feature extraction and template management lower host-side processing needs. Straightforward connection: use USB for PC integration or UART for microcontroller and embedded applications. Reliable operation in everyday conditions: designed to handle variations in finger moisture for fewer false rejects and smoother user experience.
