摘要： A device for deactivating price tags of the kind provided with a magnetic strip intended to form part of an anti-theft store security system, said device being intended for use together with a so-called scanner used to optically read a bar code on an item of goods . The invention is characterized in that the deactivator (2) includes two or more mutually adjacent and mutually parallel rows (4, 5) of permanent magnets (6, 7), where the magnets (6) in one row (4) form pairs of permanent magnets, partly with surrounding magnets in said row and partly with adjacent magnets (7) in an adjacent row (5), said pairs (6, 7) being disposed in a plane which is completely or substantially parallel with the plane in which the bar code on a goods item is located when reading said code; in that the south pole of a first magnet (6) in said magnet pair is located on a magnet surface facing away from the deactivator (2) and the north pole of said first magnet is located on a magnet surface which faces towards the deactivator (2); and in that the respective south and north poles of a second magnet (7) of said magnet pair face in opposite directions.
