Skimmers are illegal card readers attached to payment terminals — like gas pumps — that grab data off a credit or debit card’s magnetic stripe without your knowledge. Skimmers are nothing new, but technology has made them smaller and harder to find. Sometimes, they’re even hidden inside a gas pump.
Criminals sell the stolen data or use it to buy things online. You won’t know your information has been stolen until you get your statement or an overdraft notice.
Here are tips from the FTC to help you avoid a skimmer when you gas up:
Look at the card reader itself (image above). Does it look different than other readers at the station? For example, the card reader on the left has a skimmer attached; the reader on the right doesn’t.
Note the images to the left. Make sure the gas pump panel is closed and doesn’t show signs of tampering. Many stations now put security seals over the cabinet panel. This is part of a voluntary program by the industry to thwart gas pump tampering. If the pump panel is opened, the label will read “void,” (bottom image) which means the machine has been tampered with.

You can try to wiggle the card reader before you put in your card. If it moves, report it to the attendant if you have the time. Use a different pump.
If you use a debit card at the pump, run it as a credit card instead of entering your personal identification number (PIN). That way, the PIN is safe and the money isn’t deducted immediately from your account. If that’s not an option, cover your hand when entering your PIN. Scammers sometimes use tiny pinhole cameras, situated above the keypad area, to record PIN entries.
Monitor your credit card and bank accounts regularly to spot unauthorized charges.
If you’re really concerned about skimmers, you can pay inside rather than at the pump.
Another option is to use a gas pump near the front of the store. Thieves may target gas pumps that are harder for the attendant to see.
If your credit card has been compromised, report it to your bank or card issuer. Federal law limits your liability if your credit, ATM, or debit card is lost or stolen, but your liability may depend on how quickly you report the loss or theft.
Consider placing a fraud alert or a credit freeze on your credit report. This requires businesses to confirm your identity before approving applications in your name.
