FIELD: banknote authenticity checking methods, possible use in banknote sorting machines.
SUBSTANCE: in accordance to the invention, a banknote is scanned on both sides using scanning devices, resulting image is checked for match of position of image elements with standard image, in case of full match of images of banknote with standard image, banknote is deemed fit for payment, in case of partial match, metallography image contours are selected for each side of banknote, after than match of mutual position and geometric dimensions of metallography elements with the standard is checked on each side of banknote.
EFFECT: increased banknote sorting quality in real time due to detection of banknotes, produced by gluing parts of various parts of banknotes together.
