1 Product Overview
JM-101 fingerprint module is an integrated fingerprint processing module that integrates optical path and fingerprint processing. It has the characteristics of small size, low power consumption and simple interface. It has high reliability, fast recognition speed, good wet and dry finger adaptability, and fingerprint search. high speed.
JM-101 module communication interface is USB and UART
2 Working principle
1, fingerprint characteristics
The feature extracted by the fingerprint algorithm from the acquired fingerprint image represents the information of the fingerprint. Fingerprint storage, comparison and search are all done by manipulating fingerprint features.
2. Fingerprint processing consists of two processes: fingerprint login process and fingerprint matching process [where fingerprint matching is divided into fingerprint comparison (1:1) and fingerprint search (1:N)].
When the fingerprint is registered, each fingerprint is entered twice, and the recorded image is processed twice, and the composite template is stored in the module.
When the fingerprint is matched, the fingerprint image is entered and the fingerprint image is verified and processed, and then matched with the fingerprint template in the module. If the template is matched with a template specified in the module, it is called a fingerprint comparison method, that is, 1:1. Mode; if matching with multiple templates, called fingerprint search mode, ie 1:N mode), the module gives the matching result (pass or fail).
