First Claim
1. A communication partner appliance comprising:
- a transmitter configured to transmit a near-field communication (NFC) command signal to another communication partner appliance according to an active communication mode, wherein the command signal includes a request for data from the other communication partner appliance; and
a processor coupled to the generator and the transmitter, wherein the processor is configured to switch from the active communication mode to a passive communication mode in response to a determination that the response signal is not received from the other communication partner appliance.

Abstract
A communication partner appliance is implemented within a near field communication system. The communication partner appliance includes a receiver, a detector, and a processor. The receiver receives a NFC command signal from another communication partner appliance. The detector detects whether a carrier signal from the other communication partner appliance is present at the receiver at a time other than during a transmission of the NFC command signal from the other communication partner appliance to the receiver. The processor controls a power supply element based on a determination by the detector whether the carrier signal from the other communication partner appliance is present at the receiver. The power supply element is configured to establish a connection to either a first power supply or a second power supply. The first power supply is dependent on the carrier signal, and the second power supply is independent of the carrier signal.
