What would be wrong with OCR plus a marker or two to indicate a scannable area (and maybe content type) - human readable, phone scannable. My biggest issue with QR codes is there is no indication of what they are before scanning. That, and I dislike most forms of advertising. |

* There is no OCR that is currently sufficiently reliable
* It has no error correction ability, so is not robust against damage
* There are currently no apps I know that can perform this function
So go to it, create an app that works on all known phones and is robust against up to 30% damage, and you may have something with which to penetrate the market.
My phone tells me what it is and asks permission to open it, and the context usually tells me what it should be. I don't bother with context-less QR codes. Beside, this is not a problem with the code, it's a problem with the brain-dead manner in which some people use them. I scan codes for shows, films, and shops. I know what I'm getting, and it's simple, clear, and my choice. I don't like advertising either, but sometimes I see notices of things I want to use, see, or get involved with.
