The inventions relate to checking devices and in particular to devices for money documents checking and can be used for detection of counterfeit money documents - banknotes. Claimed inventions work is based on the fact that banknotes owe their individual uniqueness comprising such a complex as producer, nominal value, individual number (usually represented by its alphanumeric assignment). Detection of banknotes with the coinciding individual characteristics at several payees makes it evident that at least one of such banknotes is counterfeit. Method of identifying banknotes defective in uniqueness is as follows: banknote identification data values are inserted to the memory of data store, incoming banknotes accepted by the payee are identified by recognizing required banknote characteristics which determine identification data of these banknotes and by their transforming into digital signals, digital signals are transmitted via electronic communication channels, digital signals values corresponding to incoming banknote identification data values are compared to values of identification data of banknotes in data store, if a coincidence in digital signals values with values of identification data of banknotes in data store is detected, a decision is made on detection of banknotes defective in uniqueness, payee which has sent digital signals is identified, results of comparison to be sent to him, period of actuality is established within which incoming banknote identification data remain vital for a particular payee, digital signals are formed in such a way that they correspond not only to incoming banknote identification data but also to the established actuality period of these data, digital signals values corresponding to incoming banknote identification data are stored in the memory of data store taking into account the established actuality period of these data. |
