'The tyranny of apps': those without smartphones are unfairly penalised

That way you both get to take the full price from people whose time is expensive enough that they won't bother with the apps, and also those who wouldn't pay the full price but have enough time to use the apps.

I never eat McD's, but I see the pattern everywhere. If you make between the minimum and average wage in Slovenia and don't own property, you practically can't get by without dedicating 6h per week to grocery shopping in various different 'discount' chains (Lidl, Hofer AKA Aldi Sud, Euro Spin), keeping up with the weekly discount catalogs and using all the app discounts (more recently).

By tying your service to a smartphone your are basically refusing to provide service if the costumer doesn't agree to Apple's or Google's TOS. If the app doesn't complain about emulation or something different than Android or IOS you are in luck, but that's not the case with most banking apps. And that's only talking about people who don't have it by choice and have money to buy one.

For me, once, it went beyond: I took my first dose of the Covid vaccine, and the second dose's date would still be announced. I asked where it would be available to the nurse, "On the Instagram page of the ". "But i don't have Instagram" i said, and the nurse shrugged. It requires both a phone and a social media account with your real info, but since absolute nobody complains about it they just do because it's easier.

This will continue as long people are complacent with it. In some places the government is required to provide you services, by law, by any means available and not depending on 3rd party service, but they do require apps anyway and people stay quiet. Phones as an alternative is fine, it's a tool, but should not be an obligatory device for you to be considered an human being.

To answer that question with any degree of rigor one has to go back to the beginning and study the works of Bentham, Mill and others—and the many issues that surround utility and utilitarian principles. This involves such issues as the greatest good for the greatest number, greed overpowering well established moral norms and the fact that the majority of modern states and cities were founded on utilitarian models where a lot of give-and-take was involved before workable consensuses were achieved.

Think twice, the obvious solution doesn't always turn out to be the most optimal one.
