摘要

The invention relates to a document comprising at least one antenna (112; 112.1, 122.2, 122.3, 122.4) for the contactless coupling of electric energy of an electromagnetic field, at least one memory (110) for storing an executable program (108), processor means (105) for executing the program, the processor means being designed to automatically start executing the program as a result of the coupling of the electric energy, and signal generation means (101) for generating an input signal (S) to be entered into the program after the execution of said program has been started by the processor means as a result of the coupling of the energy, the signal generation means being designed such that the input signal depends on an antenna voltage that is induced via the field into the at least one antenna.
