Then we have another problem. Cashlessness. There are fewer and fewer places that accept cash for payment and even if they do some of them won't have change (since it's so rare that other people are paying in cash).
I have a friend now who was cut off from the BankID (and thus cashless) system and it's quite a struggle for him. He has to constantly have other people (i.e. us) do things for him, or drive 40km to one city or another during specific hours to do things (since all the local outlets for everything closed since 99% of people do 99% of everything online now).
