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