Thank you for your request.
Paying with a gift card is the same as paying with a credit card. The gift card must be inserted into the card slot. This is only possible if the “Geschenkkarte” logo is displayed on the machine (see scan).
If you have any questions about the ticket machines or need help, you can call our Hotline on +41 800 11 44 77.
You will find more information here.
I wish you a nice day.
