The payment screen may look fairly simple but is a complicated product that is in fact realized by many different parties. Depending on the selected payment method and the chosen bank, the user is redirected to a different website. All these different websites are subjected to the IT policies of a different company or bank. All it takes is for just one of these IT policies to introduce a strict 'x-frame-options' policy (or announce its future introduction) and your consumers will no longer be able to pay via that channel. Also from a viewpoint of user experience and accessibility, we are not big fans of this option. For this reason, we have introduced an adjustment that blocks the use of the payment screen in an iframe.
