Chinese officials are telling people to be wary of circulating fake currency notes. From BBC:
A People’s Bank of China statement said low-quality counterfeit detectors did not always manage to spot the fakes.
But it said the telltale signs could be spotted with the naked eye, and urged people to be vigilant.
“Though mostly counterfeit 100-yuan notes [worth $14.60] are not too hard to make out, people should be careful as cash transactions during the Spring Festival are high,” the bank statement said.
“The fake notes start with ‘HD90’ and are aimed at cheating detectors, and some poor-quality detectors are easy to cheat,” Ye Yingnan, of the central bank, was quoted by the Beijing News as saying.
