FIELD: physics.
SUBSTANCE: marking system consists of threads with super-soft ferromagnetic properties, placed on the surface or inside a substrate in accordance with predetermined parallel positions with constant spacing on a predetermined array. These threads can be present or absent in each of the positions, thereby forming the detected binary code. The marking system can be made, particularly in form of tags with a magnetic code. Proposal is also given of a continuous production method of such a type of marking by incorporating ferromagnetic threads into an adhesive complex.
EFFECT: simple and cheap system of marking, which provides for exclusive reliability and coding using a maximum number of combinations.
