Abstract:
In accordance with a first aspect of the present disclosure, a communication device is provided, comprising: a first antenna configured to receive and transmit a first set of near field communication (NFC) signals, wherein said first set of NFC signals relates to NFC transactions; a second antenna configured to receive and transmit a second set of NFC signals, wherein said second set of NFC signals relates to wireless charging operations; a controller; a first interface between the controller and the first and second antenna, the first interface comprising an antenna selection unit configured to select the first antenna or the second antenna in response to a selection signal received from said controller; a second interface between the controller and the first antenna; wherein the controller is configured to detect whether an external communication device is within communication range of the first antenna using the second interface. In accordance with a second aspect of the present disclosure, a corresponding method for operating a communication device is conceived.
