Abstract: The invention relates to a merchandise securing device (1) comprising at least one merchandise securing element (4, 5, 15) and a closing mechanism (6) with a fastening element (8) that can be inserted into a clamping element (18, 19, 20) of the closing mechanism (6) similar to a needle. Such a merchandise securing device (1) is provided with a housing contour that is essentially flat in the attachment area (14) in which the merchandise securing device (1) is fixed to the merchandise. The merchandise securing device (1) comprises a recessed closing mechanism (6) while the at least one merchandise securing element (4, 5, 15) located in or on the merchandise securing device (1) uses acoustomagnetic (AM) technology and/or radio frequency (RF) technology and/or radio frequency identification (RFID) technology.

Abstract: Security elements that are flexible, that can be used for merchandise and preferably can remain on the merchandise, that are difficult to locate, that can be incorporated into the merchandise during its manufacture and that have a simple design, i.e., merchandise security elements that can be economically produced and used. A merchandise security element which is intended for use in connection with acoustomagnetic merchandise security systems formed of a flat section of a swingable metal foil and a flexible, magnetic metal foil which are arranged in an overlapping fashion within a predetermined surface region and which are fixed relative to one another by means of a non-conductive spacer that cannot be magnetized and is arranged in between the two metal foils within the overlapping surface region.

Abstract: In order to largely protect an anti-theft element for acoustomagnetic anti-theft systems which contains a module that is accommodated in a housing and has a magnetic element as well as a thin metal plate from manipulations, in particular, deactivation by strong magnetic fields, without a noteworthy enlargement of the structural size, the invention proposes to realize the magnetic element in the form of magnetic foils that are polarized with a north pole alignment and a south pole alignment, respectively.
