The Shopsite shopping cart protects merchants from fraud caused by mailicious attempts to modify payment information for either PayPal and Worldpay transactions.

Since both PayPal and Worldpay take the client away from the Shopsite store to their respective sites it is important that Shopsite merchants feel confident that the information inputted into these respective payment processors has not been tampered with when the client is returned to the Shopsite Thank You page.

If any of the customer's payment information is altered the Shopsite merchant is notified by email!
