An identification plate having a chip module that includes a chip, a coupling element connected to the chip, and an antenna module comprising an antenna lead. The coupling element is coupled to the antenna lead by a coupling field that creates a contactless coupling. An adjustable damping element is arranged in the proximity of the coupling element. The damping element projects into the coupling field and dampens the coupling field. In this manner, a maximum value of a transmitting and receiving range of the identification plate can be reduced.
