From the Configuration Menu, click Payment → Credit Card Types
On this page, you can add/remove credit card types that your site will accept. The card types listed here will be visible to your customers on the payment page during checkout, and will be sent to the payment gateway if processing live transactions, so they must be valid card types.
NOTE: Adding a new credit card type might require customization of the gateway code. Please contact your developer for assistance.
Adding a Card Type
To create a new credit card type, click the 'Add New' button and fill in the name of the card type.
Removing a Default Card Type
If you delete one of the 4 default card types (VISA, Mastercard, AMEX, and Discover) you should also remove the image of it that appears on the checkout page, to avoid confusion. To do this, edit the /skins/skin_#/images/creditcard.jpg file to remove the image of the card you removed.
