An apparatus comprising: a passive RFID module; characterized in that the apparatus further comprises a control module,coupled to the passive RFID module through a wired connection, configured to receive an electrical signal from the passive RFID module through the wired connection; wherein the control module comprises a controller, a reader sensing element electrically coupled to the controller, and a touch sensing element electrically coupled to the controller, and wherein the control module is configured to determine, based on a characteristic of the electrical signal as presented to the reader sensing element or to the touch sensing element, whether the passive RFID module has been energized by an RFID reader, or, in the alternative, has exhibited a change of impedance as a result of the proximity of a human or a touch panel accessory; wherein the apparatus is configured to operate in at least two modes, including: a first mode if the control module determines that passive RFID module has been energized by an RFID reader, or, in the alternative, a second mode if the control module determines that the passive RFID module has exhibited a change of impedance as a result of the proximity of a human or a touch panel accessory; the passive RFID module is disposed proximate to a touch panel, and in response to the determined change of impedance, the control module is configured to indicate that the human or touch panel accessory has made contact with the touch panel. a passive RFID module; characterized in that the apparatus further comprises a control module,coupled to the passive RFID module through a wired connection, configured to receive an electrical signal from the passive RFID module through the wired connection; wherein the control module comprises a controller, a reader sensing element electrically coupled to the controller, and a touch sensing element electrically coupled to the controller, and wherein the control module is configured to determine, based on a characteristic of the electrical signal as presented to the reader sensing element or to the touch sensing element, whether the passive RFID module has been energized by an RFID reader, or, in the alternative, has exhibited a change of impedance as a result of the proximity of a human or a touch panel accessory; wherein the apparatus is configured to operate in at least two modes, including: a first mode if the control module determines that passive RFID module has been energized by an RFID reader, or, in the alternative, a second mode if the control module determines that the passive RFID module has exhibited a change of impedance as a result of the proximity of a human or a touch panel accessory; the passive RFID module is disposed proximate to a touch panel, and in response to the determined change of impedance, the control module is configured to indicate that the human or touch panel accessory has made contact with the touch panel. a first mode if the control module determines that passive RFID module has been energized by an RFID reader, or, in the alternative, a second mode if the control module determines that the passive RFID module has exhibited a change of impedance as a result of the proximity of a human or a touch panel accessory; the passive RFID module is disposed proximate to a touch panel, and in response to the determined change of impedance, the control module is configured to indicate that the human or touch panel accessory has made contact with the touch panel.
