I’m also bothered by very detailed QR codes. Milk cartons in my country had a QR-code for their website. It would be a ~10 letter url, maybe with a short path. But for some reason, the QR code was extremely detailed, as if it contained several kilobytes of data. I’m not sure if there were a large number of tracking-related parameters in the url, but it was very obviously unreasonably large.
Strongly agree on this one. Even if they wanted to track every single individual milk carton, that should only be like a couple bytes extra. Overly complex QR codes look ugly and are harder to scan
The complexity is likely a product of redundancy and error correction in the QR code rather than making it unique. You begin to run into issues with camera resolution and whatnot, but in theory those codes are likely more reliable.

QR codes have built in redundancy and error correction, though. I guess if they had it turned up to the max for some reason?
yeah, qr codes have different levels of error correction that you can specify, could very be well turned up to the max
or the url has a ton of tracking params appended to it for some reason
Ideally you should use a short URL that redirects to the full URL. The tracking parameters should be on the long URL, not the short one.
Yeah - that’d be my guess for an over-complicated code with minimal info.
Scan one and find out
