Mechanical sympathy for QR codes: making NSW check-in better

Since most government software is written in Java, the QR codes on PDF check-in posters are probably being generated with ZXing .
Need a QR Scanner to move codes from iPhone to Mac

If you don’t want to install that command, or don’t know how to use the Terminal, then decode the QR image using this website: https://zxing.org/w/decode.jspx . The code is open-source if you want to inspect it: https://github.com/zxing/zxing
Generating a QR code with only ARM Assembly

zxing has an online decoder -- https://zxing.org/w/decode.jspx -- but I've seen it fail so often that I'm wondering whether it's very "strict" / doesn't account for image distortion that much?
Or does the web site use hardcoded settings that are more tweakable in the library?
Huh, interesting -- zxing is in "Maintenance Mode Only": https://github.com/zxing/zxing
I'd be suuuuper interested to know: what's the state of the art in terms of QR decoding, both in terms of decoding speed, amenability to various image distortions, and (which I've always dreamed of) the ability to partially decode a QR code, even if the error correction fails for some parts of it, or even totally? i.e. a very very verbose debugging/decoding mode?5 projects | news.ycombinator.com | 8 Sep 2021

There is no real specification. This is the best source, which documents QR standards.
>There are some standards -- de facto and otherwise -- already in use. This wiki attempts to catalog some possible standards for encoding various types of information, and suggest a standard action associated to them.
Trying to scan a very strangely designed QR code
1 project | reddit.com/r/learnpython | 14 Jun 2021
https://github.com/zxing/zxing is able to scan the code just fine. Maybe give that library a shot - it is used in multiple mobile scanners, like QR Droid.

- give my name + phone number to people (avoids spelling issues and typos).
I simply wrote some text corresponding to a wifi network and a vcard (see  for how this looks like) and show that text as QR code.
