The embedded iFrame allows you to be in control of your check out process and keep the look and feel of your web site.
The iFrame module can be applied on any ecommerce site’s payment form.
IFrame takes sensitive data, subject to PCI compliance (usually credit card number and CVV number), transmits it to the System for tokenization and returns it in a form of a Token back to your application. This way, sensitive data never touches your server and you keep the token for further transactions with this credit card.
