Bank notes stamped with QR codes for breaking China's Internet firewall

Anti-censorship campaigners have found a novel way of scaling the Great Firewall of China, printing QR codes on bank notes which when scanned take people to a site where they can download software that bypasses the country's Internet access restrictions. According to the Epoch Times, a woman called Mrs Wu recently noticed something odd about the four one yuan notes in her change at a supermarket in Wuhan. The notes all had QR codes stamped in the top right hand corner, along with the words "Scan and download software to break the Internet firewall."
