摘要：
A conventional magnetomechanical EAS marker is modified to aid in authenticating an article of merchandise to which the marker is to be applied. The marker includes a housing, a magnetostrictive element in the housing, a bias magnet mounted to the housing, and an authentication element in the housing for indicating the authenticity of the item to which the marker is to be applied. The authentication element may be a printed logo, bar code or character string or a discrete element having distinctive or rare characteristics.
