to the example in fig2 a hearing device 10 is to be programmed with a transponder 11 to this end the hearing device 10 possesses a so called u201c wireless system u201d which aside from data can also transmit energy to external circuits this transmission system is symbolized on the part of the hearing device 10 in fig2 by means of an antenna coil 12 the transmission system and or the antenna coil 12 is connected to a memory 13 in which programming data for the signal processing facility 3 compare fig1 can be stored the latter is however not shown in fig2 for the sake of clarity in addition the hearing device 10 still has a so called u201c pushbutton u201d 14 which has to be pressed in order to program the hearing device 10 the transponder 11 in particular an rfid transponder represents a circuit which is external to the hearing device said circuit being able to communicate wirelessly with the hearing device 10 to this end the transponder 11 possesses an antenna 15 which is embodied as a helical coil on a flat substrate which preferably has the form of a check guarantee card the antenna 15 is connected to a microcontroller 16 and this is in turn connected.
