Abstract:
The invention relates to a transponder unit (1) and to a method for transmitting data between the transponder unit and a reader (100). The aim of the invention is to increase the transmission range of the transponder unit (1) to the reader (100). For this purpose, means are integrated into the transponder unit (1) for actively transmitting a signal to the reader (100). The reader (100) evaluates said signal as a modulation of its own field (110) by a transponder.
