Editorial narrative

The RAK12001 WisBlock Fingerprint Sensor Module is based on GROW R307. This module supports both fingerprint enrollment and fingerprint matching. When enrolling, you need to enter the finger two times. The system will process the fingerprint images, generate a template of the finger based on processing results and store the template. When matching, the sensor will determine if the finger placed in its optical sensor has a match on its memory.
