I don’t think more than a handful of Europeans have ever heard of wiring the way you describe. Everyone over here has a bank account with a debit card and is used to transferring money to someone using their international bank account number; PayPal is in use for convenience, but not really necessary actually. People have credit cards for travelling abroad or online purchases, but that’s about it.

not more than a large handful of Americans have heard of it either, till they become "established" so to speak. It's for moving large amounts of money, and for ordinary people that would only be like when you buy a house, you wire the money to escrow. Europe has the same wire system, it's international.
