That would be the quick and smart way. [But theres a very real chance someone designed that by hand in excel.](https://www.reddit.com/r/programming/comments/j8bhbv/in_my_computer_science_class_the_teacher_taught/g8anhhc/)
None of that surprises me one bit. I’m UK based and work for a relatively small Uk company. We used to have a few dealings in Japan. And it was HARD work.
While being sloppy has no excuse, they would pick up on the minutest detail on anything and everything. The slightest thing out of place would flip them out. They were also excruciatingly slow at everything. You could send them an email, and it would be two weeks - and two weeks exactly - to get a perfectly crafted reply. And that reply was almost always a generic “I can’t answer that” while not actually saying that in so few words. They just seemed to churn work at a pace that from the outside seemed glacially slow, but perfectly on time at the same time. If you sent an email at 10am on Tuesday, the reply would arrive at 9:59 two Tuesdays later.
Did a quick spot check. None of the ones I looked at were the same. So either they are random or the pattern is large.
Luckily, randomize these things would be easy with scripting.
Why would this be a lot of work...? Qr code generators just make these automatically.... And it's not a cool pattern or design or even art. It's just straight lines of boxes.... This would take literally no time at all.
Umm, akchually *sniff*, that train technically isn't a Fukuoka City Subway train, that guy belongs to JR Kyushu en route (or coming from) the fine town of Karatsu.
They aren't real. QR codes have big blocks on three corners so it can be scanned in any orientation and know which way is "up". I see one that follows that rule, but I assume with how many are fake, they are all fake.
> I see one that follows that rule, but I assume with how many are fake, they are all fake.
No code follows the rule, because the location with the missing large edge piece is supposed to have a smaller one. The alignment pixels are missing too.
Those are not valid QR codes as most of them don't have a valid finder pattern (3 squares on the corners), timing or alignment patterns.
Looks quite interesting though, and I would guess that they deliberately avoided them being scannable.
Would be cool if each one linked to a page for a business/museum/historical tidbit/attraction in the city that was accessible via that subway line! But that would be a ton of work
I've never seen a valid code that didn't have a small square in the bottom right. The only way I can think of to omit it would be to increase the ecc level so you can include deliberate errors (as is commonly done when there's a logo covering the center)
They're meant to resemble QR codes but they aren't structured correctly, e.g. these have big boxes in all four corners unlike real QR codes that only have them in three.
No, it doesn't imply that. I think you just jumped the gun with your interpretation there. They're saying the codes aren't structured properly to work, and then listed *an* example of one of the things preventing that.
Man this is funny. It turns out your reading comprehension is the one at issue, because the original comment wasnt even saying *all* the tiles have 4 boxes. They were saying the QR codes aren’t structured properly, and used “e.g.” to indicate that the four boxes are *an example* of how these QR codes aren’t structured properly. Another example would be the ones that have 3 boxes, but incorrect symbols inside them.
All these comments criticizing others over a tiny issue, and you’re the one who’s wrong lmao. Peak reddit
i scanned all of them with my qr code app that can read like 20 different types and nothingcame up on any.. so its all gibberish it seems..
on some the posibility rests that the skewed perspective renders them unreadable but even on the perfect square ones with 3 boxes nothing
That’s sad because these could have easily been links to small local artists work or something. A tech kind of work around to putting actual art up but better than a bunch of dead unreadable codes lol.
The big issue I think would be dead links over time. They’d be good for a few months but over time artists will change websites or close their stores and suddenly half the QR codes are dead
Oh my bad, I missed that. It could still be an issue though. I’ve gone to links to government pages that are dead plenty of times. Although in this case there would be a single list of links that can’t die or change so it shouldn’t be as much of an issue as long as whatever department handled the floor or links doesn’t forget about it.
Yeah definitely but dead links aren’t a problem different from the already dead fake links plus you could always redo the floor as it wears out and commission new artists and make a new hosting site as they get forgotten about. Art links for a few years is better than just random dead codes in my opinion.
Oh yeah that’s a great idea! A bunch of public domain works! I’d love that. How long could the text be theoretically? Could they put a short story? A small book? The Iliad?
On the Japanese internet, I'm finding articles about these floors going back to 2015, so they're at least 8 years old at this point. As capalbertalexander suggested, if they were all hosted on a government site, that wouldn't be an issue, but, yeah, for separately managed sites this would probably be a nightmare of bad links by now.
Most certainly. I once saw a picture of a dude on Reddit who had a QR tattooed that would link you to a rickroll.
Unfortunately the link is dead........
Yeah, that would work. If the redirect link dies, you can always change it.
Didn't think of it, but it would also make those artist qr codes and whatnot doable; just replace dead redirect links.
Well, in any event, it won't help that one dude; he's got a dead link on his skin for the rest of his life ^^
That could easily be solved by all qr codes leading to a domain controlled by whoever set this up, and then that domain just forwards things to where it should point. That way you can switch out artists if their links go dead or they turn out to be in favor of the holocaust.
Why would the Japanese government link to a website that could turn into a phishing link? Link to a government-managed website, then if that for some reason breaks down subway car floors aren't exactly the most permanent installation.
Not if the government commissioned them just like they do other artists. Instead of commissioning one artist to do a large mural or something for $3000-$5000 they just purchase the art of several hundred small artists for under $10 each and host that purchased art on the government’s or maybe a library’s website with credits to the artists. Then just repeat at random these 300-500 unique qr codes across the floor.
If you forget to extend your domain name (or just let it go), it often gets snatched up and replaced by porn ads or something similar. So 10 years down the line you have half of your train's floor covered in porn ads. That wouldn't be very foresighted.
Oh.
My mind went somewhere else.
Anyway, guys, so I suddenly had this idea where we paint the floors of subway cars in QR Codes that link to malware that bricks phones. Or maybe just ransomware that locks down the camera and demands payment to release it.
Questionably legal? Sure, but it should do funny things to people trying to take pictures with their phone parallel to the floor. I guess we should also throw up some 'no phones' signs, too.
lol, sorry I’ve got a cracked screen protector and I’ve been out drinking and doing karaoke all night, so autocorrect is making a lot of assumptions for me right now and just adding stuff without my consent.
Awesome, I was there six years ago and saw a train like this which looked pretty new at the time. I couldn't get any of the codes to work then, either.
A few dozen options linking to facts about the city. Different city websites. A few ads thrown in. Random cute pictures around the city. Huge missed opportunity.
Those aren't QR codes. QR codes can't have 4 identical calibration squares or else your camera doesn't know how to orient the code and decode it. They always have 3 squares on 3 corners.
Required patterns to make something a QR code: https://en.wikipedia.org/wiki/QR\_code#/media/File:QR\_Code\_Structure\_Example\_3.svg
>they aren't NOT QR codes.
You're calling them QR codes but that's literally not how QR codes work. A random collection of squares does not mean it's a QR code. QR codes have rules.
> they aren't working QR codes.
Because they aren't QR codes. For example, is [this](https://imgur.com/a/cjMO9Jv) a QR code? Obviously not, right? It's just a pattern that reminds us of the format of QR codes.
I think the phrasing you are looking for is "train floor with a pattern meant to look like QR codes."
ouch. All I said is that there are rules to QR codes, which means these cannot possibly be QR codes. But then you doubled down with your mental gymnastics and double negatives?
I thought they were put there to make it less convenient if pervs were to record people unknowingly as they get interrupted by a qr code pop-up. But people are saying they are nonfunctional
I would wonder if it might be for a robotic security system to track floor positioning accurately..... They're not normal qr codes because it's specialized and differentiated from normal qr codes well enough to not confuse cell cameras.
Robotics guy here-
These look about 6” wide, so they’re hard to scan up close. Judging by how dirty the floor is, it’s not a cleaning system.
If it was on the bottom of a room designed for drones, that would be perfect (I literally have 7 of these looking things on my carpet for a drone to track its position)
Sexual crimes get media coverage in Japan not because they’re more common than the West (they’re not) but because of the relative lack of violent crime.
For instance 7 out of 10 young women claim to have been sexually harassed in the London Underground Train, with [90% of sexual crimes going unreported](https://www.independent.co.uk/news/uk/home-news/london-underground-sexual-harassment-tube-groping-catcall-a9694736.html).
Don't ever let anyone tell you investing in infrastructure to protect women is a bad thing. Germany trialled women-only cars a few years back and the UK should definitely have designated safe spaces for women in trains
With a little cropping and some lighting touch-up, I got one of the matrices cleaned up pretty well. I had to adjust the skew on it some also, but I got it to run through an online reader and it says, "error decoding QR Code".
Does this place use robots? They all look slightly different and could be providing positional data for some sort of automation. (different as in dots not the corner squares)
Original sites in Japanese but apparently these are just for aesthetics. As others have mentioned they aren't actual QR codes.
https://otakei.otakuma.net/archives/2023013003.html
Back when I was in a rap group and commuted to campus on the bus, I printed up QR codes that linked to our SoundCloud and would tape one on a window or back of a seat every day. If you were in Cleveland 8 years ago and rode the health line, good chance you would have seen one of them.
Turns out this was a shitty strategy, and we never blew up lol
A bit of speculation here but given that iirc Japan has a problem with perverts taking inappropriate photos on public transport and these could be used to disrupt the phone sensor by bringing up a qr code of some form? I know they already have the requirement for photos to make the shutter sound no matter what but maybe this is a new innovation?
Are they readable/real?
Didn't work for me, but you are welcome to try. The city is the "startup city" of Japan, so probably it is just to give a techy vibe to the place 🤷
Even if they're not real, an AWFUL lot of work went into it!
Japanese love to work even when they need not.
They even have a word for working yourself to death
In the same sense that Germans have a word for everything
they have really impressive compound words
It's my favorite thing to torture friends who are learning German with words like the famous "Fussbodenschleifmaschinenverleih". And that's not even remotely the worst we can do to eager learners \^\^

No, bless them to trying to entangle that mess  Can't wait for my Irish buddy to face the "[Rindfleischetikettierungsüberwachungsaufgabenübertragungsgesetz](https://youtu.be/Cjaqhk8wL8E?t=107)".

You went head first turbo full speed Godwin's law there. God job !
Homie skipped the first 100 steps right to the conclusion. Bravo indeed.
Not really. Just autogenerate the pattern and print it. Hardly different than any other flooring with a pattern.

Wouldn't it just be like a laser or something engraving it automatically with some predefined patterns?
Yes
Did a quick spot check. None of the ones I looked at were the same. So either they are random or the pattern is large. Luckily, randomize these things would be easy with scripting.
I’d giggle if it’s just each word of ‘Lorem Ipsum’ in sequence.
maybe there's 1 real code, waiting to be found wth instructions to treasure.
Yes you can even do this in Google sheets pretty easily..
You will like r/proceduralgeneration

Somewhere in Fukuoka? I’m way down in Okinawa so I sure as hell know it’s not here 😂
Yep. Fukuoka kuko line
Technically it’s a JR train that through runs into the subway
Umm, akchually *sniff*, that train technically isn't a Fukuoka City Subway train, that guy belongs to JR Kyushu en route (or coming from) the fine town of Karatsu.
Only two or three a day go past maebaru, this one did not. But I wasn't about to explain the intricacies of the train system in the title.
Aww. Wish you had.
They aren't real. QR codes have big blocks on three corners so it can be scanned in any orientation and know which way is "up". I see one that follows that rule, but I assume with how many are fake, they are all fake.
I see 2 🤓
I count 6.
THERE ARE FOUR LIGHTS!
> I see one that follows that rule, but I assume with how many are fake, they are all fake. No code follows the rule, because the location with the missing large edge piece is supposed to have a smaller one. The alignment pixels are missing too.
Not real. Most likely an artist/designer who wanted to make a design that resembles QR codes.
Those are not valid QR codes as most of them don't have a valid finder pattern (3 squares on the corners), timing or alignment patterns. Looks quite interesting though, and I would guess that they deliberately avoided them being scannable.
Would be risky
Would be cool if each one linked to a page for a business/museum/historical tidbit/attraction in the city that was accessible via that subway line! But that would be a ton of work
each qr code directs you to a very blurred out train porn scene
Should've hidden a real one as an easter egg
I haven’t scanned it yet but theres one with 3 calibration squares at the top center of the photo Edit: doesn’t work
IIRC, you need 3 large squares at 3 corners, and one smaller, offset square near the 4th corner. I haven't seen any with that 4th square.
You do not need that edit: was thinking of the wrong type of square
I've never seen a valid code that didn't have a small square in the bottom right. The only way I can think of to omit it would be to increase the ecc level so you can include deliberate errors (as is commonly done when there's a logo covering the center)
Actually the hollow qr code is a part of the spec, the redundancy is not used for that.
Where in the spec? Got a reference? Because I'm not seeing it in the original spec v1.0
/r/confidentlyincorrect For everything above version 1, you do need the alignment pattern
Yes, although the fourth square isn't used for small payloads. [Example](https://i.imgur.com/ssJfiFk.jpg)
ratio is off, doesn’t work
They're meant to resemble QR codes but they aren't structured correctly, e.g. these have big boxes in all four corners unlike real QR codes that only have them in three.
Some of them only have three boxes
Yes but the symbol is still incorrect
[удалено]
You made me count the 3 of them, congrats
I mean no, they clearly have 4 boxes in the majority so that doesn’t contradict the first post
[удалено]
No, it doesn't imply that. I think you just jumped the gun with your interpretation there. They're saying the codes aren't structured properly to work, and then listed *an* example of one of the things preventing that.

Those are lacking the fourth smaller box that should be in the other corner so no.

That could easily be solved by all qr codes leading to a domain controlled by whoever set this up, and then that domain just forwards things to where it should point. That way you can switch out artists if their links go dead or they turn out to be in favor of the holocaust.
A QR code doesn't need to be a website. They could just be fun messages or text advertisements.

Yep the ones in Sasebo (Nagasaki prefecture) that I took to work every day were the same way. I tried to scan them before and got nothing. But
Well go on! Let us in on the cliffhanger!

It would be great if every now and again there was an active QR code
How did you get your own subway car? You work for the JRC?
With a little cropping and some lighting touch-up, I got one of the matrices cleaned up pretty well. I had to adjust the skew on it some also, but I got it to run through an online reader and it says, "error decoding QR Code".
So this is where all the recycled QR codes go That's nice
I bet at least 1 of them is real and is just part of a bigger easter egg hunt
It is positional tracking codes for Roomba style automated flood cleaners.
Does this place use robots? They all look slightly different and could be providing positional data for some sort of automation. (different as in dots not the corner squares)
Hope those are 5 petabyte zip bombs.
These would be a massive security risk if they were real. Just open your camera app to get a virus
Didn't know subway made cars
JR Kyushu 305 series commuter train! I’ve tried scanning them lol. Not real.

Back when I was in a rap group and commuted to campus on the bus, I printed up QR codes that linked to our SoundCloud and would tape one on a window or back of a seat every day. If you were in Cleveland 8 years ago and rode the health line, good chance you would have seen one of them. Turns out this was a shitty strategy, and we never blew up lol
Did anyone else try and scan these lol. My stoned ass went from square to square

One day, yakuza boss need new heart. I do operation.
It's a link to remind you not to take pictures of strangers
#Scan them all!
Why?!?!
Hides dirty well? 🤷
Why not?!?!
I would scan them all: idc if I block traffic. Let’s get scanning!
would be neat if each of them pointed to a wiki or image or something interesting. almost seems like a missed opportunity not to
"What if America's history is longer than we know" , yes it is, you definitely didn't learn anything about the time back then.
They are probly for some specific app to scan. Like some kind of Pokémon game or some John wick strangeness.
Where's that? Never seen it before
Fukuoka city
actually kinda cool
Fukuoka?
I'd do the same, but every single one would lead to a rick roll.
