Banknote serial number processing method and its device
First Claim
1. A banknote serial number processing method comprising:
- a banknote serial number recording step which comprises converting a banknote serial number into an image signal by using an image capture device;
a banknote serial number recording decoding which comprises processing the banknote serial number image signal by filtration, analogue-digital conversion and synchronizing separation and storing the processed image signal in an image memory unit;
banknote serial number digital signal processing step, which involves stored image recognition processing, identifying a bundle code and storing the banknote serial number and the bundle code in digital memory;
a reading step for a banknote serial number to be compared, involving sorting out a corresponding banknote serial number from a bundle code to be compared, then storing the sorted out serial number in a reading-in memory unit;
a comparison step involving a comparison of the banknote serial number to be compared and a newly recorded banknote serial number comprising comparing the newly recorded banknote serial number with banknote serial numbers in memory in the reading-in memory until a same serial number coincides and activating an alarm relative to a same serial number coinciding, and wherein the banknote serial numbers in memory are for non-counterfeit banknotes obtained unlawfully.

Abstract
Banknote serial number processing method and apparatus having a serial number recording step where images of serial numbers associated with to-be-newly recorded banknotes are subjected to image recognition. Image recognition is followed by a conversion step involving a conversion of the image recognized serial numbers to digital data inclusive of digital serial number data and bundle codes. There is also a comparison step which includes a comparing of digital data produced in the conversion step with read-in or provided serial number data, with the provided serial number data being derived from a database containing serial number data of non-counterfeit banknotes which represent banknotes unlawfully obtained by a third party. Comparison hits trigger an alarm and/or forwarding of information, while non-comparison hit banknotes are forwarded to memory with associated bundle coding.

17. A banknote serial number processing method, comprising:
-
a banknote serial number recording step wherein a stack of to-be-newly recorded banknotes, which have images of serial numbers associated with said to-be-newly recorded banknotes, are subjected to image recognition, wherein the image recognition includes image recognition of serial numbers of the to-be-newly recorded banknotes; a conversion step comprising a conversion of image recognition serial numbers to digital data inclusive of digital serial number data and bundle codes respectively assigned to each of a plurality of sub-groups of converted image recognized serial numbers; a comparison step which includes a comparing of digital data from said conversion step to provided serial number data, with said provided serial number data being derived from a database containing serial number data of non-counterfeit banknotes which represent banknotes unlawfully obtained by a third party. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26)
