Abstract

A wireless communication device (102), for providing at least one Near Field Communication service to a user, comprises at least one application element for use in providing the at least one Near Field Communication service, and a communication section (204) for providing a communication link between at least one Near Field Communication target device (106) and the wireless communication device (102) when the at least one Near Field Communication target device is within a Near Field Communication range of the communication section. The communication section (204) is arranged to detect a break in a communication link between the wireless communication device (102) and at least one Near Field Communication target device. An interface element (213, 215, 404, 500) notifies the at least one application element when at least one Near Field Communication target device is detected within the Near Field Communication range and the at least one application element is arranged to communicate over a communication link with a detected at least one Near Field Communication target device. The interface element (213, 213, 404, 500) generates and sends to the at least one application element a target removal event in response to the communication section (204) detecting a break in a communication link between the wireless communication device (102) and a detected at least one Near Field Communication target device.
