Credit card fraud is big business. Where should the blame fall? Fraudulent transactions are twofold. Individuals are responsible or should be for the physical presence of their cards. When they lose their credit card, it places a burden on some unlukcy merchant. The second fold is the merchant. There are things merchants can do to help prevent fraud. One important technique retail merchants can do is ask for a customer’s ID when processing a credit card transaction. Keeping an eye on chargebacks is very important for any merchant. If you receive too many chargebacks, you will have issues with yourprovider. Retail merchants can also compare the signature on the back of the card to how they sign the receipt. If there is no signature line present on the back of the card, ask the cardholder to sign it. Also, watch their behavior, do they seem nervous or acting funny? A lot of fraud happens online too as making a fraudulent transaction at a retail store takes more guts than making a purchase on the Internet.
