FIELD: physics.
SUBSTANCE: invention ensures high speed deposition of unique marks, which have high stability against damage and destruction. The method and device are used for deposition of unique composite labels and markings on sequence of products, in which each unique composite mark has two or more signs. At least, part of each mark can be put together on the predetermined place, and such combined arrangement is unique and individual for each composite mark and for each product. A code (for example, alphanumeric code), which is saved in a data base can be derived from composite mark. Thereafter, access to the code for identification and verification with the mark can be received.
EFFECT: providing of high speed deposition of unique marks, which have high stability against damage and destruction.
