RALEIGH, N.C. – Skimmers at the gas pump is a problem that isn’t going away, and the North Carolina Department of Agriculture is taking steps to ensure those devices are spotted quickly and removed, WNCN-TV reports. Recently, one North Carolina gas station discovered skimmers installed at the pump four different times in one month.

During its routine inspections of gas pumps, the agency looks for skimmers as part of its checklist. “[Skimming] certainly is a growing problem,” said Stephen Benjamin, director of the N.C. Agriculture Department Standards Division. “It’s a routine part of our inspections now to look for those skimmers.”

But with those inspections only happening annually, the department decided to ramp up efforts to combat skimming in other ways. To do that, the agency has been developing a training program for convenience store employees on how to spot skimmers or suspicious activity around the gas pump. The program will have online photos and reference material for gas station workers.

Obvious signs of tampering include broken security tape or ill-fitting card readers. Benjamin said the training program will teach some of the basic security measures employees can take to combat skimming. “If they walk around [the pumps] a couple of times a day and inspect [them], that’s an opportunity to take a glance,” and ensure the pumps haven’t been tampered with, he said.
