It’s not quite like that where I am. I know in the US anyone can walk into the bank of the other person and get stuff done. And there’s not even a surcharge for that IIUC.
And I don’t suppose many cashless banks exist in the US. Indeed, there are banks that simply cannot handle cash even if you have an account with them. I.e. no vault! Nowhere to put cash so you cannot make a cash deposit. If you need cash and your ATM card isn't working, these cashless banks have a bizarre hack: the clerk makes a temp emergency card, walks out of the bank to an ATM with you, pulls the cash out, and hands it to you. But not the card. If you need cash again and your card still doesn't work, you have to repeat the nannied process during banking hours. It’s like that in Denmark.
Theoretically I can go into a post office and pay them a fee to send money. But the hunt for criminals and the #warOnCash has lead to the payer being required to show a smartcard ID. In my case the software run by the post office took a shit and froze. I can only guess why.. possibly because the chip showed I was not registered as an official resident- which is not required unless I’m staying more than ~6 months or so. I bounce around so it wouldn't be sustainable for me to register as a resident even when I'm not, just to overcome a programming fuck up every time I need to send money.
Apparently the system has been hardwired to make some foolish assumptions by reckless people who find it acceptable to marginalize nomads/road warriors, anyone with an unconventional lifestyle, etc.
