Are you paying with the tap card or do you just show it and then pay with cash/card?

You show the tap card and pay cash. With tap card it is 50¢

You can pay with the tap card of you have credit on it. If you have a day pass (1 or 3 day tap card) then you have to pay cash. 50 cent per pax.

I think you have to pay with cash/card at the top. That's what I saw everyone else doing so I did it

You can also pay per cash or credit card at the top.

You can pay with it.
