    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.

          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.

              Why is that ideal? Seems more prone to problems if the short URL service shuts down or suffers outages.

                You don’t have to use a third-party short URL service. It can be hosted on your own site.

                A lot of people are already using a third-party short URL service like qrco.de because they don’t realise you don’t actually need a service like that to make a QR code.

                  Regardless, why bother running or using a short URL service? QR codes can easily hold a full URL and more, and QR codes are not (nor are they meant to be) human readable, so what’s the benefit?
