That's not a thing in (most countries of) Europe any more. I was shocked when I came to the US and saw that checks are still in use
A cashier's check is like a domestic SWIFT.
Some people/business will still ask for a cashier's check though.
It's difficult to imagine in a modern world, people or institutions writing or printing something on a piece of paper, and saying, "here, this is money".
Got stuck behind someone at the Carrefour (grocery store) paying with one. Ugh.
