Abstract
Provided is a mutual-capacitance palm print identification method, a mutual-capacitance palm print identification device and a mutual-capacitance palm print identification touch panel. The method includes: forming a palm template information by using a mutual-capacitance touch panel to acquire a capacitive sensing data obtained from a palm pressing by a user; forming a current user's palm information by using the mutual-capacitance touch panel to acquire a capacitive sensing data obtained from a palm pressing by the current user; and comparing the current user's palm information with the palm template information and outputting the result of the comparison. It is unnecessary to add extra parts for the present invention, and thus the cost is low. Moreover, a palm of a living body is required, it is difficult to be cracked and counterfeited.
