Product description:

R308 is a separate fingerprint reader, used high speed special DSP as core parts, compatible different fingerprint sensor. It is an intelligent module which can freely get fingerprint, image processing, verified fingerprint, search and storage, and it can work normally without upper monitor’s participatory management. Fingerprint processing includes two parts: fingerprint enrollment and fingerprint matching (the matching can be 1:1 or 1:N). Enrolling fingerprint, user needs to enter the finger 2-4 times for every one finger, process finger images with many times, store generate templates on module. When fingerprint matching, enroll and process verified fingerprint image And then matching with module (if match with appoint templates on the module, named fingerprint verification, For 1:1 matching method; if match with many templates on the module, named fingerprint search method also named 1:N) system will return the matching result, success or failure.


Main Functions:

1. Integrated image collecting and algorithm chip together, ALL-in-One.
2. Fingerprint module can conduct secondary development, can be embedded into a variety of end products.
3. Users can conduct secondary development, can be embedded into a variety of end products, such as: access control, attendance, safety deposit box, car door locks.
4. Low power consumption, low cost, small size, excellent performance.
5. Professional optical technology, precise module manufacturing technics.
6. Good image processing capabilities, can successfully capture image up to resolution 500 dpi.
7. A total of eight instruction, Convenient MCU development.
8. Finger detection signal output.
