摘要：
A magnetomechanical EAS tag (10) having a bias magnet (18) made of a high magnetostrictive material so that stress, which is a result of ordinary use of an article (12) incorporating the tag, demagnetises the bias rending the EAS tag inactive is provided. In an alternate embodiment a mechanical mechanism is incorporated with a conventional EAS tag to deactivate the tag upon ordinary use of an article to which the tag is associated. In yet another embodiment, a combination of the bias magnet made of a high magnetostrictive material and a mechanical deactivation mechanism is used to deactivate the EAS tag during ordinary use of an article to which the tag is associated.
