The wireless interface 6 is preferably configured to maintain a wireless link and/or to communicate over a wireless link with a selected wireless enabled device only as long as the selected wireless enabled device is shown in the currently acquired image. In other words, only when the user holds the mobile device such that the selected (target) wireless enabled device can be seen through the camera of the mobile device the wireless link is active, otherwise it is switched to inactive state or even completely terminated. This provides a high security that the wireless link is only maintained with the desired wireless enabled device and, in particular, that a desired task (e.g. data is transmitted) is only performed with said wireless enabled device and not with any (not visible) wireless enabled device. To help the user of the mobile device to hold the mobile device in the direction of a selected wireless enabled device the display is preferably configured to display a guidance signifier, e.g. an arrow pointing into the direction into which the mobile device shall be moved and/or tilted.

As explained above the wireless interface 6 is preferably configured to transmit probing signals and receive response signals from wireless enabled devices to identify said wireless enabled devices, the capabilities of devices including a wireless enabled device and/or one or more parameters of said wireless enabled devices. Further, in an embodiment the wireless interface 6 is configured to receive a beacon signal transmitted by a wireless device, said beacon signal including one or more parameters of a detected wireless enabled device.
