FIELD: information technology.
SUBSTANCE: method of making a nano-barcode is realised by applying a basic digital barcode and an individual digital barcode while forming an irreproducible picture in the space between them, wherein the irreproducible picture 5 is formed on nano-paper made by pre-addition of a nanopowder additive to a paper mass, followed by making sheets of nano-paper and simultaneously fixing the arrangement of nanoparticles 6 relative each other in both the space of the irreproducible picture and between the stripes of the basic barcode 2 and the individual 4 barcode.
EFFECT: high reliability of identifying barcodes, easier and safer method of making barcodes.
