Abstract
A tag for an electronic article surveillance system which includes a circuit means for reradiating a predetermined tag signal and voltage dependent means in circuit with the circuit means. The voltage dependent means has a capacitance which can be varied with a change in voltage to selectively enable the circuit means and disable the circuit means from being able to reradiate the predetermined tag signal.
