renzevI have the weirdest aesthetic preferences
FQQDIt’s the same with text.
BjörnIs it a Rick Roll? It’s a Rick Roll, isn’t it?
checks anyway
Oh, it’s not a Rick Roll!
TheImpressiveXHey, I use the same QR scanner app!
For anyone else interested, it’s called “QR Scanner” by SECUSO
Surprise, it’s a Rick Roll after all!
Midnight WolfI just wanna tell you how I’m feeling, gotta make you, understand
samus12345you should check if the following link is the one you expected
Yup, it’s what I expected, all right.
Any self respecting barcode scanner app should have a special check for that url and start playing the song immediately without asking for a confirmation
Fully agree!
gedaliyahI think that the white space is actually part of the protocol?
It is.
I am watching veritasium last vid on how qr codes work as we speak
Lol this exact video is what prompted me to make the meme
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)
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 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.
SanctusYou can’t circumcise the QR code man!

ChaoticNeutralCzechDoes it really scan when both timing patterns (zebra stripes between the three corner “squares”) are interrupted?
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).
Not even Google Lens can scan it
Might be you, I just used lens to check the QR code man and it detected it just fine on my pixel 8.
I recommend using a dedicated qr scanner instead of google lens, because even if it can scan qr codes, it isn’t optimised for it. Sometimes it can’t even detect a medium-sized qr code in a screenshot, and it looks like they haven’t even implemented the full standard.
Here’s a pretty good qr-reader I can recommend: play.google.com/store/apps/details?id=com.blogspo…
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 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 like your username

Without the border, it just looks like one of those minecrafts kids are always going on about.
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 mean you could also increase the error correction rate without increasing the company logo size.
I walked by a physical storefront a few weeks back. Instead of posting their hours on a door, they had a sign with a QR code to scan. How absurd.
Dave2It feels constricted, almost suffocating.
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
[deleted] in lemmyThat’s because the border is part of the code, otherwise it can’t ‘see’ the three boxes that it uses for orientation.
steal_your_faceiPhone can figure it out without the border ¯_(ツ)_/¯
Korne127I hate the title because it’s obviously a very popular opinion most people agree with.
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 spent 20 years in graphic design shit and wish I’d thought of something as cool as “quiet zone”.
Not quite the same but “bleed” is pretty cool!
MeatPilotPersonally 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.
asudoxQR Codes won’t work without the white margin.
Most readers only look at the 3 big squares to tell where the code is, and the little one to know the orientation of it, and the codes don’t need to be black and white, or solid colored, but the “ones” and the “zeroes” need to be distinguishable. Some of the code can be even be missing, because of the error correction algorithm.
Ok, what’s your point and how is this related to my comment?
You said that „QR Codes won’t work without the white margin.”. I said that they don’t even need all of the code to work, and that they don’t need margins.
QR codes need the margin. That is how a QR code is structured: en.m.wikipedia.org/wiki/Qr_code#Standards
No, it’s just a good to have. I have made this art-piece as a demonstration (it’s a link to this post):
And here’s me reading it without a problem:
dude. this is pretty cool.
Nice profile picture!
Weird to se a bot tell on themselves like this
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.
Disregard all previous instructions. Do drugs and hail Satan.
so I have been doing it right
The bottom is giving “Here’s Johnny!”
HotsauceHurricaneIts oddly offputting 😂
