At the weekend I was in an area next to Stuttgart and on the way to the tram station there was a self checkout station for buying pumpkins.
Typically you pay in cash. But this one had a PayPal account linked. That's what I call modern!

Na so lange ich trotzdem mit Bargeld zahlen kann passt das ja.

that is what i called thumb, becuase i don't want that the companies know what i buy (in summary). one step more to a panopticum state.
Sure, you can still pay with cash. But on the other hand people are complaing they can't pay cashless in the bakery etc. So this approach is ideal.
no, it's not ideal for me, because most people don't have any awareness for the subject. in addition, most people are comfortable so that this lazyness wins.
