Abstract
A method for use in a touch-sensitive panel includes generating electric fields by applying drive signals to a plurality of row electrodes and a plurality of column electrodes included in the touch-sensitive panel, and sensing at least one information signal capacitively coupled to the touch-sensitive panel by detecting impedance changes associated with the plurality of row electrodes and the plurality of column electrodes. The impedance changes are converted to received data. Based on the received data a transmission pattern associated with the at least one information signal is determined. It is further determined that the transmission pattern corresponds to an identification code.
