Problems solved by technology

[0011] Thus most of the solutions that have been proposed are still quite complex and expensive and do not lead to an improvement in safety, recalling the complex and difficult control of magnetic phenomena
Specifically, in some systems that employ lengths of wire or ribbon with magnets, blocking the wire or ribbon may cause changes in the response of the system
Furthermore, these known systems can only offer a limited number of combinations similar to barcodes to achieve real coding, or they have to do so at the expense of excessive complexity, either in the label itself or in the "reading" of the label. detector aspect, to achieve this encoding

Embodiment Construction

[0070] figure 1 A magnetic label in the form of a magnetically encoded label 1 is shown. The label comprises a carrier sheet 2 with a rubberized side, and a protective sheet 3 of the siliconized paper type initially applied to the rubberized side of the carrier sheet 2 .

[0071] Parallel positions 4 spaced apart by a fixed "pitch" or interval "e" are predefined on the magnetically encoded label 1 . Parallel wires 5 having ultrasoft ferromagnetic properties are laid in some of these predetermined positions 4 . The absence or presence of lines 5 at each possible position 4 defines a detectable binary code specific to each tag 1 .

[0072] The marking advantageously also comprises a first wire 6 having ferromagnetic properties at the end of the label 1 in order to mark the beginning of the "read" zone in which the other wires 5 are located.

[0073] By simply attaching to the glued side of the carrier sheet 2, all the threads 5 and 6 are fixed in their predetermined positions...

Abstract

The invention relates to a marking system (1) comprising a wire (5) exhibiting ultrasoft ferromagnetic properties. Said lines are arranged on or in a carrier (2) and are associated with predetermined parallel positions (4) separated by fixed intervals (e) according to a predetermined frame. The line (5) may or may not be present at each position (4), forming a detectable binary code. The marking system (1) of the invention may in particular be embodied as a magnetically encoded label. The invention also relates to a method for producing such a marking system by successively embedding ferromagnetic wires (5) into an adhesive composite (2, 3). The marking system of the present invention is used to identify and authenticate items, products and objects.

Description

technical field [0001] The present invention generally relates to the marking of items, products or objects in order to identify and / or authenticate them. More specifically, the present invention relates to a system for security marking by "reading" "magnetically encoded tags" with the aid of suitable detectors. The marking system according to the invention has various applications: [0002] - Prevent counterfeiting of industrial products by authenticating original products; [0003] - traceability of products or articles by batch or product sequence or possibly by individual articles; [0004] - To identify products or items in the flow of commerce in addition to or possibly as an alternative to conventional optical barcodes. Background technique [0005] Currently, the identification of articles or products with light barcodes is well known, but it involves some disadvantages. In particular, optical barcodes are easily imitated or modified with the aid of scanners and ...
