ABSTRACT:
An antipiliferage tag comprising a soft-magnetic thin film (100) for use as an active element in an electronic article surveillance (E.A.S.) system. The film (100) has an easy axis (102) with a particular direction. The tag has been folded along at least one folding line (104) so that the tag comprises at least two layers which at least partially overlap with each other. The folding line (104) forms an oblique angle different from zero with the direction of the easy axis (102) so that the direction of the easy axis (102) in one layer is different from the direction of the easy axis (106) in another layer. In this way an antipiliferage tag which is insensitive to its orientation in a detection gate of an E.A.S. system is obtained.
