Abstract
Currently, the magnetic ink anti-counterfeiting technology has been widely used in the anti-counterfeiting manufacture of RMB, bank tickets, credit cards and other valuable tickets. However, the advantages and disadvantages of the anti-counterfeiting function are directly related to the vital interests of the state and the public. The intelligent manufacturing level of magnetic ink anti-counterfeiting technology is increasingly higher, with the improvement of modern technology. This paper firstly searches, counts and analyzes the domestic and foreign patents of magnetic ink anti-counterfeiting technology, summarizes the trend of patent application for magnetic ink anti-counterfeiting, and analyzes the patents of key nodes. Secondly, The development route of magnetic ink anti-counterfeiting patent technology from technical issues, patent application time, key technologies and other dimensions, and depicts the evolution map of magnetic ink anti-counterfeiting technology are summarized. Finally, the development trend of magnetic ink anti-counterfeiting technology is summarized and analyzed, and then the future development direction of patent technology and reference ideas for future technology development and patent application are provided in this paper, this contributes to the improvement of magnetic ink anti-counterfeiting technology.
