If it's anything like speeding tickets in most of Europe your place of residence determines whether you have to pay on the spot or not. For example Netherlands and Germany (and many others) have an agreement in place where your home country collects the fines so you don't have to pay on the spot. But if you're from a non-EU country you'll almost certainly have to pay on the spot because there would otherwise be no way to collect the money if you refused later.
