Photo of QR codes in China

This giant wall of QR codes was in the Shanghai Urban Planning Exhibition Center. I thought it would come in handy sooner or later when I come to write an article about QR codes. There are several different QR codes represented here, although some patterns have been repeated. I don't know if these are genuine QR codes or mock-ups. Since they were rendered as white on white using height to differentiate the pixels, they're unlikely to work on most devices.
