If you do business on the Web, you should guard against credit card fraud. These tips can greatly reduce online credit card fraud:
- Require a credit card verification number on all purchases. Referred to as a CVV (card verification value) or CVV2, this three-digit number is located on the back of every Visa and MasterCard.
- use an account verification system. Known as AVS, this system checks on the billing address of the card to make sure that the zip code and other information matches.
