FIELD: process engineering.
SUBSTANCE: invention relates to marking of goods. In compliance with proposed method, primary and individual barcodes are applied with non-reproducing pattern made there between. Said pattern is created by preliminary mixing of the elements of contrast colours with their subsequent sintering. Said elements are made of nanoparticles sized to 5-100 nm in conical ledge with its narrow part facing the barcode surface. Now, at least two reference points are applied thereto to create a virtual info reticle.
EFFECT: better protection against counterfeit.
