Remember to register your credit card with 3D Secure at a bank.
It is a security requirement that your card must be registered with 3D Secure. This is at least valid for Dankort, Visa Dankort and Mastercard.
To improve security, we require that all cards used on this website be registered with 3D Secure.
How does it work?
Once you pay by credit card on the website and your purchase has gone through, a one-time PIN code will be sent to your phone. You will need this code to complete your purchase.
If you experience problems with your purchase with us, please contact your bank’s support and state your telephone number amount you use in connection with your purchase. Your credit card may not be approved for 3D Secure by the bank.
