On the Digital pass page you can make a digital copy of your dance school membership card, and then keep it in the wallet app on your phone. The card carries over your name and the same barcode that is on your plastic card — so you do not have to carry that around.
You find the page in the header menu: on a computer under "More", on a phone directly in the menu. You do not have to log in for it; the pass is made without an account too.
For now the pass of one single dance school can be picked, that of Goldance Tánciskola — if yours is not on the list, you cannot make a card yet.


The pass ends up where you make it, so it is worth starting on your phone right away: Apple Wallet and Google Wallet are both to hand there, and scanning the barcode with the camera only makes sense there. A card made on your computer does not move over to your phone by itself.
