IDENTIFICATION RECOGNITION DEVICE AND METHOD OF OPERATING AN IDENTIFICATION RECOGNITION DEVICE

摘要

An identification recognition device includes a light emission module, a light sensing module, a pulse scanning unit, a fingerprint scanning unit and a controller. The light sensing module is used to generate first light currents and second light currents according to first reflecting light and second reflecting light. The pulse scanning unit is used to generate data of current variance of the object and the fingerprint scanning unit is used to generate features of fingerprint of the object. The controller is used to control the light emission module to emit the first incident light and to emit the second incident light when the object has a pulse according to the data of current variance of the object, and determine if the object passes the identification recognition test according to the features of fingerprint of the object.
