Visit China to see a cornucopia of QR codes. Everything there is QR codes. Almost all payment is done through scanning a QR code (even tiny stands by the side of the road). Public transportation is accessed through QR codes. Adding people on social networks is done through QR codes. Some restaurants don't even have menus and you access their menu via a QR code (and of course pay again through the same). QR codes everywhere.

Ironically in China the popular name for QR Codes is 二維碼 (literally "2D code"). This is disappointing because there are other types of 2D barcodes (Data Matrix, Aztec, PDF417, etc.) and because it fails to acknowledge the QR brand.

  Isn't it more like it's calling a square a rectangle? All these codes are 2D codes - the general public doesn't care if it's a QR Code or DataMatrix or Aztec etc. Anyway, the Baidu Wiki [0] says QR Code is a kind of 二維碼.
