Features: 1. The R300 Fingerprint Module uses small-area capacitive surface acquisition chip and integrates fingerprint algorithm chip with functions such as fingerprint entry, image processing, feature extraction, template generation, template storage, fingerprint comparison and fingerprint search. 2. Fingerprint reader can be embedded into various end products such as: access control, attendance, safety deposit box, fingerprint lock. 3. Low power consumption, low cost, small size, excellent performance. 4. Professional identification technology, precise module manufacturing technic. 5. Good image processing capability, high speed fingerprint acquisition.
