Yes. Iceland has a system called the kennitala. It's kind of like a social security number, except not secret. If you give me your kennitala and your bank account number (10 digits), I can send you any amount of money, no lower limit (there might be an upper one, I haven't tried buying a house GIRO) without paying a fee, regardless of which bank you're with. When I sign a rental agreement with my landlord, I give him my kennitala and no other details. He sets up a recurring payment request linked to my kennitala. Every month, the bill shows up in my account with a request to pay it, but it's not like a credit card charge, it's merely a request for payment, kind of like the inverse of me inputting my landlords bank details and kennitala myself. I can ignore it if I want to. Because the kennitala is independent from the bank, I can change banks and my landlords rental bill, along with all my utilities bills, will automatically start showing up on my new account without anyone doing anything.
