Abstract: A mobile device detects proximity of a keyboard accessory. The keyboard accessory includes a full keyboard configured to receive keystroke input from a user and to wirelessly transmit keystroke signals to the mobile device. The mobile device activates, based on detection of the keyboard accessory, a near-field communication (NFC) interface to generate a carrier field that provides power for the keyboard accessory.

Abstract: The invention relates to an electronic device comprising a control unit, a memory comprising a first and a second application, an user interface arranged to enable a file to be selected and to present a content of a file, and a transceiving unit, wherein the control unit is arranged to control the first application to feed a selected file of a first format to the transceiving unit for transmission to a predetermined database, and to control the second application to present the content of the selected file in a second format using data received over the transceiving unit from the pre-determined database sent.
