Think of it this way, a QR code is binary. If you modify color spaces correctly you can get 6 bits (or more) per pixel. In addition, you can improve the detection at distance, localization for robots, and speed (120 fps).
Done this to great effect previously and you can do a lot of awesome things with it. Pretty much the easiest hack in computer vision.
