R503-S Fingerprint Identification Module Why choose this module All-in-one fingerprint processing: built-in full fingerprint identification algorithm and protocol handles fingerprint collection, template comparison, search and storage on the module itself, reducing host CPU load and simplifying system design. Low-power operation: supports low power finger recognition to extend battery life in portable or battery-backed applications. Compact, install-ready design: stainless steel thread sleeve and a 22 mm installation opening make mechanical mounting quick and robust. Key features and benefits Functionality: Captures fingerprints, compares live scans to stored templates, searches the template database, and stores up to 150 fingerprint templates locally. This lets you implement authentication or identification without continuous host-side processing. Sensor and performance: Capacitive 160 x 160 pixel fingerprint sensor provides reliable capture of fingerprint detail using capacitive sensing technology. Compatibility and upgrade path: R503-S is developed from the R503 family and is suitable as an updated option where R503-based designs are used, enabling broader application support without redesigning core systems. Installation-ready hardware: Built-in stainless steel thread sleeve streamlines panel mounting; the required installation hole diameter is 22 mm, simplifying mechanical design and replacement. Application flexibility: The updated product design supports a wider range of use cases and environments where compact biometric identification is required. Practical use scenarios Door access control: Integrate R503-S into cabinet locks, turnstiles, or door controllers to provide local fingerprint authentication with a small installation footprint (22 mm panel hole). Time and attendance for small/medium deployments: Store up to 150 employee fingerprints locally for reliable clock-in/out without relying on continuous network connectivity. Equipment or cabinet security: Add biometric access to industrial equipment or secure enclosures where low power consumption and a compact, threaded mounting are important. Technical highlights (concise) Model: R503-S (based on R503 series) Sensor: Capacitive, 160 x 160 pixel Storage capacity: Up to 150 fingerprint templates Main functions: Fingerprint collection, comparison, searching, storage Power: Supports low power finger recognition Mounting: Stainless steel thread sleeve; installation opening diameter 22 mm Design note: Updated model to support broader applications The R503-S offers a compact, integration-friendly solution when local biometric identification, low power operation, and straightforward panel mounting are required.
