WILLIAMSBURG –  When you pay at the pump, your credit or debit card could be at risk.

"We always have an attendant on hand that's looking out here.  If we see a van pull up or someone we don't recognize, we are going to address that person, ‘hi, can we help you,’” explains Tony Faulkcon, who manages a Shell gas station. \

By adding small electronic copying devices, thieves can record information from every card that passes.

Because of a problem at out-of-state stores, WAWA has added even more security for credit and debit card users.

Employees check every pump, inside and out, at least three times a day, for the skimming devices.

Customer Alexis Hawkins-Smith knows it’s smart to watch incoming bills and be alert.

"Computers and technology, they can get a lot of information. Now we have to worry about getting gas," she noted.

The U.S. Secret Service says gas pumps are easy to access and easily become electronic cash registers.
