Craft workers in Japan use loupes to compare blown-up sections of counterfeit $100 bills with a sample legitimate bill expanded 400 times. A kind of counterfeit bill named "Super Z," which is said to have been made in North Korea, can only be detected in this way, according to Yoshihide Matsumura, president of Matsumura Technology in Tokyo.
