QR Codes work even if the publisher shuts down.
In case anyone else is interested: https://en.wikipedia.org/wiki/Rectangular_Micro_QR_Code

I used something like this on a large sheet and cut it into pieces for a puzzle gift to a website where people left comments. Nowadays even easier to generate nice temporary websites for such things.
The starter kit: a 21×21 board, with three 8×8 finder patterns, two 1×5 timing patterns, and 120 white and 119 black modules.
The Version 2 expansion pack includes a 25×25 board, two 1×4 timing patterns, one 5×5 alignment pattern, 76 white modules and 75 black modules.
And so on.
(I dunno about the desired ratio of individual black and white modules. I gather the general idea is to balance black and white, but does that include or exclude the fixed parts, where black is somewhat more common? Finder pattern is 33∶31 black∶white, alignment pattern is 17∶8, 1×5 timing pattern is 3∶2, 1×4 timing pattern is 2∶2.)
About 5 minutes later there was another tweet from him where:
- someone saw the original tweet (Guy 2)
- scanned the QR code
- ordered the OP a drink
- added a note to the order saying it was from Guy 2
Always loved this story.

This is a nice trick worth remembering. I have used it myself in the past. Handy not just for creating ultra small QR codes, but also for getting as much data as possible into the limits of the largest QR codes.
Or are you saying the ones you found failed to checksum?
It's cool for the receiver, but tedious for the sender (but it's a good way to help with difficult to read cursive).
Well... it wasn't QR-code but rather artoolkit markers. Let's just say I'll keep on printing them for a bit.
Maybe I can try again with the help of LLMs. Hmm not a bad idea

Here's a HN discussion from 2022 about it.

This is an interactive guide that will break down the process for your specific QR-code.
It's like in the 2000s when you opened an .exe and nothing seemed to happen ... bad news.

So, know that it may not be that seamless but I've experienced practically seamless AR, by simply opening an app camera, instead my default camera and I was able to do that to "blow peoples minds" back in 2012 - nobody had seen Pokémon Go yet and we showing them animated characters running around the actual room.
If a phone can automatically scan a QR code - which virtually all of them do, there is no reason it can't scan an AR tag built into the QR code by default also - not like a "real" reason.
I'll look into it later but I'm assuming its a bunch of excuses of the type corpos typically run with when they dont intend to do something - I dont really believe there is a patent they wouldn't infringe to keep our attention on lock - the AR tech existed 15 years ago and, just like Pokémon Go, its actually really cool stuff and has tons of very real applications that we haven't even skimmed the surface of yet.
Everyone isnt wearing smart glasses yet, but they are here for real now - ideally everything on earth is AR tagged or equivalent (there are several ways to do this now actually, tagless ways even) before we all have those glasses on - bc it will 100% certainly become so after that shift transpires.
The very fact that you even looked into AR makes you a better Boomer in my book - I'm sure a lot of Boomers on HN are like you, I will consider that more in the future when commenting here.
I hope you have a great day.
Sry for the book - I think you made me feel a little guilty, which is interesting.
