The AVS (Address Verification System) protocol that is used by both Visa and MasterCard is another highly useful tool for avoiding fraud Cheap Cigarettes Outlet. The basic assumption behind AVS is that the majority of the time the person attempting fraud with the use of compromised credit card information will not have access to the legitimate cardholder's billing address (normally the home address). Because a real-time gateway will be used, the failure response can generate further questions for the customer to answer (such as "Did you move recently?" or "Is this your billing address?") and customers should be allowed to reenter their address up to two additional times in the case of an initial failure. If failures continue after two tries, the customer should be locked out and that particular transaction reviewed and perhaps added to the fraud avoidance file. In fact, even partial matches should be reviewed for possible fraud. In the case of a mismatch or partial match, the merchant can take several other steps to determine the legitimacy of the sale Newport Cigarettes Coupons. The prospective customer can be called or e-mailed, the card-issuing bank can be contacted for verification, or directory assistance can be used to determine the billing address of the prospective customer.
