This module allows you to use the Barclays ePDQ Payment gateway to accept credit card payments. Accept payments via ePDQ. This module works in a very similar way to the existing osCommerce payment modules, in that you configure the interface between your site and Barclays ePDQ using the Admin Area. When a customer confirms their order, they are seamlessly taken to the ePDQ web site to enter their payment details. Once confirmed at the ePDQ site, the customer is returned to the checkout success page at your web site. Let us handle the epdq cpi interface and leave you ready to go.
