This extension module allows you to send the customer to USAePay for the collection of secure payment information. This eliminates the need for individual merchants to maintain their own SSL certificates.
Since every single payment form is hosted on the USA ePay secure servers, each one is automatically secured by the SSL certificates on these servers. This extension supports SHA1 encrypted hash that prevents vandals from misusing your merchant’s form on a different website.
