Product Description


        1. Integrated image collecting and algorithm chip together, ALL-in-One
        2. The flexibility to adapt to the conditions was the fingers, whether it is dry fingers, wet fingers, light texture fingerprints fingers, and old fingers, all have high recognition rate 
        3. The main application areas: can be embedded into a variety of end products, such as: access control, attendance, safety deposit box
        4. R300 which added fingerprint touch function.
