I think this just illustrates how much easier smart phones make things. If we didn’t have smart phones for example, all your interactions with the government would be as cumbersome and inconvenient as this fall back option.

So there is a requirement to scan a QR code and there is no option to enter the building for people who don’t have a smart phone?

“or need to display Vaccine status.”

You can’t display your vaccine status without a smart phone?

“My bank now requires I run their mobile App to be able to log in, even if I'm on a PC.”

Is your bank run by the government?

“Most OTP authorisation requires you to receive an SMS code.”

SMS is available on any mobile phone, not just smart phones. Also many SMS OTP implementations include the option to receive a phone call.

“Government departments are now only contactable via the Net, so a smart phone is the minimum unless you have a PC.”

Okay so the government requires you have a computer and internet access, but not a smart phone.

In the EU this fortunately can be done trivially with a paper QR code as well.
