<P>PROBLEM TO BE SOLVED: To improve anti-counterfeiting technology since even watermark technology of conventional notes is performed in other countries, and the technology for distinguishing counterfeit notes and counterfeit coins by a machine by discriminating the counterfeit notes by discriminating surface differences by the machine cannot prevent anti-counterfeiting because of accurate printing technology. <P>SOLUTION: A plurality of the world's first drawing patterns with ultratrace metal are printed on notes to discriminate the notes. Even if the printing technology is the same, a metal sensor and a metal X-ray scope are newly used for the discrimination technology of the notes to eliminate illegitimate notes. Also in anti-counterfeiting coin technology, a plurality of drawing patterns with metal and microprint are incorporated into coins, to discriminate counterfeit coins by new X-ray sensor camera technology different from the conventional coin discrimination. <P>COPYRIGHT: (C)2013,JPO&INPIT |
