Two product overview
The JM-101 fingerprint module is an integrated fingerprint processing module that integrates the optical path and the fingerprint processing part. It has the characteristics of small size, low power consumption, simple interface, high reliability, fast recognition speed, good adaptability to wet and dry fingers, fingerprint search high speed.
The communication interface of JM-101 module is USB and UART two communication interfaces.
Three working principle
1. Fingerprint characteristics
The features extracted by the fingerprint algorithm from the acquired fingerprint image represent the fingerprint information. The storage, comparison and search of fingerprints are all done by operating fingerprint features.
2. Fingerprint processing includes two processes: fingerprint login process and fingerprint matching process [fingerprint matching is divided into two ways: fingerprint comparison (1:1) and fingerprint search (1:N)].
During fingerprint registration, each fingerprint is entered twice, the images entered twice are processed, and the composite template is stored in the module.
When fingerprints are matched, the fingerprint image to be verified is entered through the fingerprint sensor and processed, and then matched and compared with the fingerprint template in the module (if it matches with a template specified in the module, it is called the fingerprint comparison method, that is, 1:1 Method; if it matches with multiple templates, it is called the fingerprint search method, that is, 1:N method), and the module gives the matching result (pass or fail).
