AS608 Fingerprint Reader Sensor Module Optical
– 100% brand new and high quality
– Made of high quality materials, durable
– M-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 dry and wet fingers, and fingerprint Search is fast.
– The communication interface of JM-101 module is USB and UART.
– working principle
– Fingerprint feature
– The features extracted by the fingerprint algorithm from the acquired fingerprint image represent the information of the fingerprint. The storage, comparison and search of fingerprints are all done by manipulating fingerprint features.
– Fingerprint processing includes two processes: fingerprint registration process and fingerprint matching process [where 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 the fingerprint is 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 mode; if it matches with multiple templates, it is called fingerprint search mode, that is, 1:N mode), and the module gives the matching result (pass or fail)
