Abstract:
A radio frequency identification tag comprising a tag circuit, a tag common electrode and a tag antenna element, the tag common electrode and the tag antenna element coupled to the tag circuit,the tag common electrode arranged for coupling to an external ground; the tag antenna element arranged for electrostatically receiving an exciter signal capacitively from an exciter and capacitively coupling the exciter signal to the tag circuit; the tag circuit arranged for becoming excited based on the exciter signal, generating a read signal and capacitively coupling the read signal to the tag antenna element; the tag antenna element arranged for electrostatically sending the read signal capacitively to a reader; and a display coupled to the tag common electrode and the tag antenna element and arranged to be responsive of a presence of the exciter signal, wherein the display is printable onto the radio frequency identification tag.
