ABSTRACT:
Items of merchandise (30) are protected from shoplifting or theft by affixing to them special responder targets (32), which are formed by drawing a material of high magnetic permeability into a thin wire and thereafter rolling the wire into a flattened strip and annealing the strip and severing the strip into individual lengths. The flattened strip may be positioned on an adhesively coated base strip (42) and covered by a peel strip (46). Slug-like deactivation elements (48) of hard magnetic material may be positioned along the strip for deactivating it.
