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. The mobile device receives, from the keyboard accessory, a keystroke signal via the NFC interface and processes the keystroke signal as user input for the primary unit
