First Claim
1. A circuit, this circuit being provided for a communication partner appliance that is designed for contact less communication and as a data carrier, this communication partner appliance being provided for a communication system with at least one further communication partner appliance, in which circuit a first communication mode or a second communication mode can be activated, and which circuit has the means listed below:
- activators for activating the first communication mode or the second communication mode, and reception means for receiving a carrier signal that is transmitted by the at least one further communication partner appliance, and detectors for detecting the presence of the received carrier signal, these detectors transmitting a carrier signal present signal in the event that the carrier signal is present, and otherwise transmitting a carrier signal not-present signal, and command signal recognition means for recognizing a command signal that can be transmitted with the aid of the carrier signal and for transmitting a command-end signal that represents the end of the transmitted command signal, and determination means for determining whether, after the occurrence of the command-end signal, at a given measurement point in time, the carrier signal present signal is present, with which determination means a first activation signal can be transmitted when the carrier signal present signal is present, and otherwise a second activation signal can be transmitted, with which first activation signal the circuit can be brought into the first communication mode with the aid of the activators, and with which second activation signal the circuit can be brought into the second communication mode with the aid of the activators.

Abstract
In a data carrier (2) which is provided as a communication partner appliance for a communication system with at least one further communication partner appliance (3, 40), a first communication mode or a second communication mode can be activated. A detection device (32) for detecting the presence of a received carrier signal (RS) transmits a carrier signal present signal (PS) in the event of a carrier signal (RS) being present, and otherwise a carrier signal not-present signal (NPS). A command signal that can be transmitted with the aid of the carrier signal (RS) triggers a determination stage (27) for determining whether after the end of the command signal has occurred, at a given measurement point in time, the carrier signal present signal (PS) is present. If the carrier signal present signal (PS) is present, the data carrier (2) is brought into the first communication mode with the aid of activators (30, 35); otherwise, it is brought into the second communication mode.

11. A method for activating a first communication mode or a second communication mode of a communication partner appliance wherein the communication partner appliance is provided for a communication system with at least one further communication partner appliance, and wherein a carrier signal is transmitted by the at least one further communication partner appliance this carrier signal being received with the communication partner appliance and
wherein in the communication partner appliance detection of the presence of the received carrier signal takes place, and in the event of the carrier signal being present, a carrier signal present signal is transmitted, and otherwise a carrier signal not-present signal is transmitted, and wherein recognition of a command signal that can be transmitted with the aid of the carrier signal takes place, and transmission of a command-end signal that represents the end of the transmitted command signal takes place, and wherein determination is carried out to see whether, after the occurrence of the command-end signal at a measurement point in time the carrier signal present signal is present, wherein a first activation signal is transmitted when the carrier signal present signal is present, and otherwise a second activation signal is transmitted, and wherein with the first activation signal activation of the communication partner appliance into the first communication mode is carried out, or with the second activation signal activation of the communication partner appliance into the second communication mode is carried out.
