Due to privacy and security reasons it is not allowed to use the Mollie payment screen in an iFrame. Because consumers are not able to see on which page the payment is actually made, we have chosen not to allow use of the payment screen in an iFrame. The consumer has to be redirected to our payment screen in a new tab or window.

The only exception is the use of Mollie Components, a standalone solution next to Mollie Checkout. With Mollie Components you can use javascript to add the fields needed for credit card holder data to your own checkout, in a way that is fully PCI-DSS SAQ-A compliant.
