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
Scan one and find out
everything is. whitespace is an important part of graphic design, especially margins. think about text that’s too close to the edge is the page or screen.
It’s like putting a glass of water right on the edge of the table. Give it some space ffs.
the bottom one is not a qr code. The padding is part of it.
It’s not just ugly, they don’t scan properly. I’ve had this problem many times on codes without padding because my email client or browser was set to use a dark theme.
It often goes unnoticed because most people are using a white or clear background that gives enough contrast.
It’s not just ugly, it’s against the spec. The quiet zone is meant to be 4 “dots” wide on all sides for the code to be optimally readable.
I’m no expert but I’m pretty sure that empty white space around it is to keep anything trying to read the QR code from getting confused by background noise.
I’m saving this for later, I have people send me print ads (yeah really) and this will help.
I think that the white space is actually part of the protocol?
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.
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
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.
I’ve never given it a single thought.
I spent 20 years in graphic design shit and wish I’d thought of something as cool as “quiet zone”.
I’ve seen at least one company press kit in rules on how to display their logo refer to it as “respect distance”.
Not quite the same but “bleed” is pretty cool!
Personally I’m going to start saying “quiet zone” instead white space. I’ll probably get dumb looks anyway.
It is not weird. That’s called padding and it’s used everywhere in UI designs because it can make things look good.
You can’t circumcise the QR code man!
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.
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: https://play.google.com/store/apps/details?id=com.blogspot.aeioulabs.barcode
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.
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.
It’s the same with text.
Its oddly offputting 😂
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 mean you could also increase the error correction rate without increasing the company logo size.
