Abstract:
1. A method for activating a desired communication mode of an ID communication partner device from a group of possible communication modes, which group comprises at least a first mode and a second mode, wherein the ID communication partner device and at least one other ID communication partner device are brought into a communication connection and wherein a carrier signal is output by the at least one other ID communication partner device, which carrier signal is received by the ID communication partner device, and wherein the carrier signal is repeatedly designated by at least one mode activation signal by the at least one other ID communication partner device, and wherein the absence or the presence of the mode activation signal is recognized by the ID communication partner device, giving a recognition result signal, and wherein, as a function of the recognition result signal, the desired communication mode of the ID communication partner device is activated, the ID communication partner device being always activated to the same mode selected from a Reader Talks First (RTF) mode and a Tag Talks First (TTF) mode when the recognition result signal indicates the absence of the mode activation signal, the ID communication partner device being always activated to the other mode of the RTF mode and the TTF mode when the recognition result signal indicates the presence of the mode activation signal, the ID communication partner device being configured to operate in the RTF mode and the TTF mode.
