Deactivatable EAS tag
摘要:
A deactivatable EAS tag in which a circuit comprising a non-linear element causes the generation of a detectable signal in response to an interrogating signal and in which a first magnetic element is arranged to be brought from a first position where the magnetic element does not short the non-linear element to a second position where the magnetic element shorts the non-linear element.
