Law enforcement officials are issuing a warning about credit card skimming at local gas stations.

Thieves pretend to be fuel pump inspectors so they can easily put skimming devices on credit card readers. Police say it is a billion-dollar industry.

In Georgia, officials have put a plan into place.

Agriculture Commissioner Gary Black said: "We've put together very quickly a pictorial directory of our team so region by region, folks that are operating gas stations, should an impostor come on the premises, they will be prepared to know whether their credentials are accurate or not."

Black said check to make sure the gas pump dispenser cabinet is closed and has not been tampered with before using it. He also says to use a gas pump closer to the front of the store because thieves often place skimmers at gas pumps father away so they are not noticed as quickly. Black also tells customers to use a credit card instead of a debit card because credit cards have better fraud protection and the money is not deducted immediately from an account.

In Florida, Commissioner of Agriculture Adam Putnam established a partnership between gas station operators and pump inspectors in light of more than 100 skimmers being found on pumps throughout the state recently.
