Finger print module

SKU: 0060 Category:


1. The fingerprint module is an integrated fingerprint processing module that integrates the optical path and fingerprint processing part. It has the characteristics of small size, low power consumption, and a simple interface. It has high reliability, fast recognition speed, good adaptability to dry and wet fingers, and fast fingerprint search.
2. When the fingerprint image is read, it has a sensitive response and judgment to the wet and dry fingers and obtains the best image quality, which is suitable for a wide range of people.
3. The self-learning adaptation function can also be customized, and the parameters are automatically adjusted according to changes in the user’s habits, climate, etc., to achieve a better match.
4. With the self-learning function, in the process of fingerprint recognition, after extracting new fingerprint feature values, the feature values are merged into the previous fingerprint features, and the more practical the use, the better.
5. The module also has an inductive finger function. When the finger is pressed to the fingerprint collection surface, the module touch pin outputs a high level.
6. The communication interface of the module is USB and UART communication interface. This module acts as a slave device, and the master device sends relevant commands to control it.
