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, then heat treating the wire to substantially increase its magnetic permeability and thereafter severing the wire into individual lengths. Several wires (32a, 32b and 32c) may be positioned on a common adhesively coated base strip (42) and covered by a peel strip (46) and wire like deactivation elements (48) of hard magnetic material may be positioned adjacent the wires for deactivating them.
