>But honestly, in 2022 it's kind of up to you to know how to scan a QR code, the same way you're expected to know how to type a domain name into a web browser.

Why? I've literally never been in a situation where I've had to scan a QR code. I do mean never.

What benefit does a system like this provide when it's always clunkier than just having a physical object?

On an unrelated note, isn't this why all the scan-this-QR-code ads fall flat? Because it takes a lot of extra effort to actually "check out more info"?

One recent example: paying bills in Switzerland [1]. Although those have to be scanned by a banking app.

It is not required to pay bills by scanning the QR code. It is perfectly possible to enter the IBAN and reference number manually as long as your banking provider lets you do so.

What is required is that you, when creating an invoice, provide the QR code for doing so.

I’m not sure were I said that it was required? I was responding to the comment. I see a huge benefit from scanning the QR code as it saves me trouble having to manually enter all the info. Older barcode style bills also worked but somehow scanning was always wonky.

Unlike a physical menu, items that aren't available can just be dynamically removed.

But is this actually done in practice?

With a physical menu they just cross it out or tell you

It is supreme when sharing links in a presentation, it is supreme on business cards (since you can quickly get all the details and add them to your contacts), and it is the best thing for wireless access (just point your phone, and you are in).

Menus in restaurants are an exception. Those are better as physical objects.

But why would I want wireless access to a network that you can join by just pointing something at it? That specifically sounds like a wireless network to avoid.

And how is a QR code the best for sharing links in a presentation? Why would people want to look at what you linked during your presentation? And if it's afterwards they would need access to your presentation anyway, no? At that point a regular URL would do too.

Why would it be a wireless network to avoid? I mean, the QR code has the SSID and Password in it. For guest networks, the information is usually put up inside the areas guests go to anyway.

The way it worked at my previous employer, you had the guest network SSID and password on the wall and then the QR code, so you didn't have to type them in. There was no difference in security, just convenience.

As for during the presentation: surprisingly often, if you are doing workshops.
