FIELD: physics.
SUBSTANCE: invention is used for inclusion into substances and compositions or for application onto surfaces of objects subject to diagnostics of authenticity. Device for identification, which is intended for placement on surface or inside object subject to diagnostics of authenticity, comprises flat polymer carrier of identification information, on one side of which previously specified identification image is placed, moreover, polymer carrier is coated on the side with identification image by film from adhesive composition, in which one or several inorganic compounds are evenly distributed, being nontransparent in visible range, each intended for reliable recognition of identification image.
EFFECT: reliable recognition of identification information with simplification of design.
