Postfinance does not automatically add payment methods for Visa and Mastercard.
Please add them manually. The titles must be Mastercard and Visa.

Then generate the three security keys with "Create user" and enter them in the Payrexx shop in accordance with the instructions in the next step.
Follow the instructions in the set-up assistant. Once you have done this, PostFinance Checkout is ready for a free test using payment screen simulators.
