The system consists of two parts, hardware and software The division is mainly linear BBC scanning circuit and singlechip system. The software part is divided into target search, character segmentation and character recognition F and for capital letters and Allah A fast and accurate method of character recognition is proposed. Key word： BBC, SCM, character recognition, image processing At present, all major commercial banks in China have carried out foreign exchange savings Yes, but how to identify fake dollars and super counterfeit in business is always A problem that is plaguing the financial world. In order to reduce bank losses, the vast majority of The number of banks in the use of foreign high-end detector combined with artificial copy Dollar number method, once stored in the discovery of counterfeit money, will be well documented, This method is not only obvious backward but also difficult to adapt to the market needs Beg.
