The links at the bottom are great reads as well, especially: https://research.swtch.com/qart https://research.swtch.com/qart I hope that QR codes become more widely used, now that iOS and Android both include QR capabilities directly in the native camera apps.

QR codes have their uses, but I can’t stand when they are placed on billboards as a link to more info. A simple URL I can read and remember for later, good luck memorising a QR code. I’ve seen too many obvious examples of a marketing team getting carried away and abusing these things. The most absurd one was on a police notice on the London Underground advising people to take care to hide their valuables from thieves. How could you find out more? By taking your 800 dollar valuable out to scan the QR code...

  That's because in the West, marketers at best tried to replicate CueCat [0] with QR codes. QR codes are infinitely more useful if tied with an action from the real world -> digital world: scan this QR code to pay for this item; scan this name tag to get my full contact card; etc. [0] https://en.wikipedia.org/wiki/CueCat https://en.wikipedia.org/wiki/CueCat

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.
