Patent ID: 8111136

Claim:
A fingerprint scanner comprising: a control module for detecting and controlling the transmission of signals; an electrical connector coupled to the control module for connecting the fingerprint scanner to a periphery device; one or more light emitting diodes (LEDs) indicators coupled to the control module to indicate operation status of the fingerprint scanner; and a fingerprint scanning module coupled to the control module to detect fingerprints and sense touches, and send fingerprint signals and touch signals to the control module, the fingerprint scanning module comprising a touch sensor for sensing different touches that represent different command signals; wherein the different touches comprises at least a first touch and a second touch, touch time of the first touch lasts shorter than a predetermined period of time and touch time of the second touch lasts longer than the predetermined period of time, the control module runs a first mode if the first touch is detected and runs a second mode if the second touch is detected.
