Also on the way in? In Austria you still need to request a ticket on the way in, but it uses number place recognition on the way out. But also you need to pay with the ticket or on the pole on the way out with contactless, which again would be on the wrong side.

Yes on the way in and on the way out. They mostly give three hours free parking so if you are there for less than that you don't have to do anything. If you exceed that you go to a ticket machine, type in your registration number and pay for the extra time before you leave. In fact my favourite one will just send you the bill in the post if you forget, but they will charge small admin fee for that (not a fine). If you remember when you get home you can pay online.
