The 100-yuan note will see its first upgrade since 2005 this November in an effort to fight rampant counterfeiting, South China Morning Post reported. While the old portrait of Mao Zedong remains, the new notes will include features such as color-changing ink and additional serial numbers. The face value of seized counterfeit money on the mainland rose from RMB329 million in 2012 to RMB532 million (US$85.51 million) last year. The central bank said on Monday the note’s design had been updated so it could be more easily identified by vending machines and automatic teller machines, which have proliferated across the country.
