Due to the decision of the risk department of card associations and institutions and the associated rules, we and therefore the organizers will not receive funds for tickets paid through the payment gateway until the event takes place. Pre-sale tickets are an important support for the organizers in preparing the events and, in addition, they are obliged to properly tax the sold tickets. The decision not to send any funds does not seem fair to us and therefore we have decided to temporarily deactivate card payments.

Why can't I pay by card here?

The GP webpay payment gateway is currently experiencing occasional stability issues. If you experience any issues, please try again later. Thank you for your understanding.
