1. A transponder that is arranged for non-contacting communication with a communication station, and that has transmission means and that has an integrated circuit having circuit connecting contacts, wherein the transmission means are connected to circuit connecting contacts, wherein an input voltage can be picked off from these circuit connecting contacts wherein the integrated circuit contains a monitoring circuit to which a voltage generated by using the input voltage can be fed and by which a signalizing signal whose waveform is dependent on the relationship between the fed voltage and a voltage threshold value can be generated, wherein the integrated circuit contains at least one data-processing circuit to which the signalizing signal can be fed for the purpose of signalizing at least two values of the fed voltage to the data-processing circuit, wherein the monitoring circuit is arranged to be controllable in respect of the generation of the signalizing signal, and wherein control means are provided for controlling the monitoring circuit in respect of the generation of the signalizing signal, which control means are arranged to generate at least one control signal.
