I have purchased a tourism tax card. Where do I see it in the app? How can I show it at a control?

You can access purchased tourism tax cards by tapping or clicking on cards at the bottom left.
You will then have an overview of all your tourism tax cards – past cards, currently valid cards and possibly cards that will only become valid in the future.
In the card overview, you will find a downward pointing arrow next to each card on the right. If you tap/click on it, you can view the respective card in full.
