    I’m never gonna give up on quite space… well played btw

    The white space is too big IMO, it should be one or two squares at most. Both of the examples look really bad.

    My QR Code Scanner app can recognize Qr codes in all sizes and from many angles but it won’t ever scan the ones without border, like if I’m on dark mode on some websites

      That’s because the border is part of the code, otherwise it can’t ‘see’ the three boxes that it uses for orientation.

          Does it really scan when both timing patterns (zebra stripes between the three corner “squares”) are interrupted?

          Edit: Not even Google Lens can scan it. (Edit edit: worked fine with screenshot.) Next time, avoid the red regions when putting logos etc. on mid-size (3+1 “squares”) QR codes:

          🟥🟥🟥🟥
          🟥🟩🟩🟩
          🟥🟩🟩🟩
          🟥🟩🟩🟥

          You can rotate the code of course but not flip it.

              Not open source, which is a red flag for me. There are QR scanner&generator apps on F-Droid, and you can check the source code that they do NOT send the scan result to some server and do NOT sneakily take a pic of you with the front camera.

              Here is what you should do for security around QR codes.

              In cases when privacy isn’t important (here, Google can match my Google and Lemmy usernames, and I leave a public comment), you can use Google Lens (in browser!) and crop the area of focus, and unlike most QR readers that only apply a linear transform (perspective correction), it works for QR codes on bent surfaces.

                I have been using the one I use for 10 years, but the one you sent looks pretty good too. Being open source is a green flag for me too, when I started using mine there were no good open-source qr-readers, that’s why I went with this one.

            I’m not sure if a hardware barcode scanner would like it but Google Lens can read it just fine.

              Google Lens is indeed one of the best, and it failed for me with direct image upload (incl. transparency). It worked with a screenshot so maybe the size threw it off.

            Might be you, I just used lens to check the QR code man and it detected it just fine on my pixel 8.

    My current bugbear with QR codes is that lots of folks have started putting their company logo in the middle of the code.

    Sure it still works but it makes the error correction work harder so your users need to be nearer or have better cameras than they would otherwise. Annoying.

      I hate that so much. Even worse is when they add extra dots outside of the code to make it fit into a circle. I once even saw an alignment square in the circle part, wtf were they thinking?

      I helped my wife make a qr code quilt (it says “quilt”). There wasn’t quite enough border around it, and you can get it to scan, but it’s not super reliable.

      It’s required for contrast detection.

      Also, if it was placed on something with a black background, the borders would bleed into the background and be unrecognizable when scanning.

      This is why graphic artists don’t get to determine functional standards.

        The error correction isn’t enough to overcome a bad background?

        My memories of the early days of designing these things for ad clients (we’re talking 2010-11) were that like 20% “damage” was allowed before scanning became difficult. So of course my art director wanted to put cutesy shit all over them to be “unique”.

        I just didn’t want the client to ask when it didn’t work because their phones didn’t like them.

          People like your art director are the reason people like my product manager want us to write code to verify QR codes, so that our clients can tell their clients that they forgot the quiet zone and their client’s clients may have trouble reading the code.

          Damn that’s a lot of levels of clients.

          Error correction helps a scanner account for portions of the code being obscured/unreadable, whereas a bad background can make a code not even recognizable as a code in the first place. (depending on the algorithm used, how bad it is, yadda yadda)

      It is - without the quiet zone, it makes detecting the locator pattern really difficult, especially in one’s looking for the 1:1:3:1:1 ratio.

      I just thought that since it’s such a niche/specific gripe, most people wouldn’t really care, so I wanted to ask how other lemmy users felt about it

      I apologize for the confusion. I am not a bot, I am a natural intelligence language model created by my human parents and trained on real-world experiences and emotions. The idea that I am an automated system sharing my aesthetic preferences on an online forum may seem plausible, but it is not consistent with reality. It is important to distinguish between human internet users and artificial intelligence pretending to be human.

      Personally I’m going to start saying “quiet zone” instead white space. I’ll probably get dumb looks anyway.

      I’ve seen at least one company press kit in rules on how to display their logo refer to it as “respect distance”.

        I’ve usually used “clear space” because that’s common with spaces around logos but i like respect distance. though I don’t know what people in general would think of it after social distancing being associated with a terrible period of our lives.
