Abstract
A low current electrostatic generator powers an electrode that, when proximate to the non-conductive outer surface of a surveillance tag, causes an electrostatic discharge to pass through such outer surface from the electrode and to be received by a conductive circuit within the tag. The resulting discharge impressed across the conductive circuit passes through a diode semiconductor included within such circuit to destroy the diode's unidirectional conducting characteristic and thereby deactivate the tag. No exposed conductive terminals are required on the outer surface of the surveillance tag, and the probe need not physically contact the tag to deactivate it.
