Your site and payment provider may have a range of fraud prevention methods in place. In addition, CSS our system allows you to implement a security process for payment by credit card (through eWay) so that when a credit card order with a new credit card is received, it is placed on hold ('pending') until credit card ownership has been verified. For registered users and customers, successful verification of a credit card means it can be used for subsequent orders without triggering further security checks. Also, if a registered user has multiple orders 'pending' against the same credit card, the system will release all orders upon its successful verification. For extra security, guest checkouts over the threshold amount (in different application sessions) will trigger the verification process even when the credit card has been used before.
