I can't find a good tool that shows all the extra parameters inherent to a QR code like error correction level, but that visually appears to have a medium EC level. As an example, here's that URL with low EC and high EC. I don't mind the longer URLs but I wish they used high/highest EC more often.
higher EC is a double-edged sword. It makes your QR more resistant to *damage* (e.g. part being obscured/dirty/etc.), but it makes it harder to scan in the undamaged case - especially if you're etching it into a block of wood, which has limited fidelity.
like, if I blurred both of your images until one stopped scanning, it'd be the high-EC one that breaks first
You know what is good EC in physical media? Really big f***ing pixels
Regardless of the EC level, if you start with a reasonable URL you're going to have a more usable result.
That's fine (in the example above, certainly there's a lot of the URL that could be removed with smarter placement in the server's URL-space), but I also don't want companies using URL shorteners or QR code URL services.
I think shorteners are fine for something like a menu, as long as it's somewhat reputable - if it shuts down or whatever, oh well, print some new qr codes
Generally companies are going to be handcuffed by their TLD. Plenty of small businesses have hefty TLDs because the short ones are taken or expensive. There's a balance, right?
very short TLDs are incredibly expensive, and for a company you'd want a longer, more descriptive TLD often anyway (within limits). Using redirects, though, is bad from a security perspective (there's no chance for the user to detect a QR code has been hijacked)
I don't think a company should really try to trim letters on their TLD to make their menu QR codes less dense. But, setting things up so there's not a long asset path to encode would be Very Good.
As you say, a balance
Binary-eye on android does that. Those are L and Q respectively. (the wood one is M) Why'd you round off the corners?
literally no good reason, it was a default on mini-qr-code-generator.vercel.app that I didn't clear
(that's the github hosted copy of github.com/lyqht/mini-qr that I like to use for code generation easily without ads and subscriptions and stuff)
Zint and zbarimg is my two Qr code go-tos
