Credit Card Scam: Both Merchants and Consumers Are Gatekeepers
Card shaving's growth comes partly as a reaction to increased high-tech credit card security steps, experts say. "As regulations and security tightened on electronic credit card processing networks, it became increasingly difficult for hackers to penetrate them," says Shyam Krishnan, an industry analyst with the Smart Cards group at Frost & Sullivan, a high-tech research and consulting firm. And so they turned to other low-tech scams, such as card shaving.
Because the scam requires clerks to enter the card number manually, merchants are the first line of defense in catching the perpetrators. These fraudulent cards usually look suspicious to begin with -- the numbers and letters often haphazardly glued on -- and that alone should raise red flags with store clerks and cashiers. However, many shaving scammers primarily use the cards in busy bargain stores where clerks are too harried to pay much attention and verification systems are so outdated that they don't require a matching ZIP code or other personal data.
"If merchants physically inspect all cards, they'll minimize the incidents of counterfeit cards being used," says Tom Harkins, chief strategy officer at Secure Identity Systems.
It's in the merchant's best financial interest to keep a watchful eye. After all, any charges made with the number would likely be disputed by the card's rightful owner, leaving the merchant with little option but to absorb the loss through a chargeback. That's why Siciliano recommends that merchants refuse service if the card doesn't scan. "Manually typing the card number in when there is even a hint of suspicion is risky," he says.
Merchants should also turn the card over and ensure the back of the card has the proper marks. For sales conducted without a card for online or phone transactions, Harkins advises merchants to protect themselves by requesting the three-number security code on the back of the card (four digits and on the front of American Express cards). "If it doesn't match, ask additional questions or investigate the customer before completing the transaction," he says.
Inevitably, some of the scammers will succeed, and unless the cardholder has a firm handle on his or her account, the crime can go entirely unnoticed. Experts say this further reinforces the need for cardholder diligence on a regular basis. "It's vital to check your balances and accounts on a regular basis and report any suspicious purchases to help identify the theft quickly," says Krishnan.
