Abstract
A capacitive input device includes sensing electrodes configured to form a capacitive coupling with auxiliary device electrodes of an attached auxiliary device. The auxiliary device electrodes transmit data signals to the sensing electrodes via the capacitive coupling. The capacitive input device also includes processing circuitry configured to decode the data signals received via the capacitive coupling to obtain decoded data.
