A bearing pressure exerted on the finger print sensor or a change in this bearing pressure is ascertained using defined grey-scale value portions of one or more successively recorded finger print images, and in the event of a specific bearing pressure being exceeded and/or undershot or in the event of a predetermined dimension for the change in the bearing pressure being exceeded, a control signal and/or useful signal is generated or a function of the finger print sensor or of an electrical or electronic device connected thereto is controlled or switched.
