This is what "Oh By Codes"[1] are for.
Instead of trying to paint a QR code, which is difficult, you can just chalk a 6 character code.
Further, you can create them on the fly without using a special tool - just a textarea on a simple webpage.
You can encode up to 4096 characters or a single URL redirect.

You can't scan them like a QR-code, which is kind of the point?
But people's phones will scan a QR code from the camera: they're much more likely to do that then type in a URL while walking.
