Re: Crowd Sourcing Broken QR Codes
#2A software tool should exist to repair QR codes. People could really benefit from it because QR codes are used everywhere.
I'd like to find a way to repair QR codes through software. However, that begins with collecting a bunch of broken and corrupted QR codes people stumble across and fixing them up by hand. This will help spot patterns in how they fail. So please help out by submitting your QR code that doesn't scan. Please don't create QR codes that don't scan just to submit them. Thank you! In the past I have fixed one QR code by hand and it is shown at the link.

#3There is a tool called qrazy box

It allows you to essentially remake a damaged or partially hidden QR code pixel by pixel, but has some limitations.

Seems that the solution is to add more redundancy (and stop covering the center pixels with an icon). The codes are designed to be self-correcting if the damage is slight enough or more redundancy is added.

If the problem is that the software can't find the centre, it could say so ,- that would hint to people that their icon is the problem

#6The most common failure case I see for broken QR codes is it scans fine but it was created using some commercial link-bouncer service and they stopped paying the subscription fees so the redirect is dead.

That would probably be closer to link rot[1].
Interestingly enough, printed QR codes physically degrading as described in the article is actual bit rot, albeit a form often overlooked.

The problem isn't that it can't find the center, it's that you reduce redundancy by replacing those pixels with the icon. It can find the center fine and still be unable to scan because there isn't enough information there.
