What Does a Skimmer Look Like on a Gas Pump?
Learn how to identify hidden skimmers on gas pumps to protect your financial information and prevent credit card fraud.
A skimmer is a device criminals attach to payment terminals, such as gas pumps, to illegally capture credit and debit card information. These devices steal sensitive data from your card’s magnetic stripe as you swipe, even if you are using a chip-enabled card. Understanding the signs of these illicit devices helps protect your financial information from compromise.
Identifying External Skimmers
External skimmers are designed to blend in with the legitimate card reader but often show noticeable differences upon closer inspection. These devices may appear bulky, extending further than the original card slot, or not fit flush against the pump’s surface, creating an unusual gap. Gently wiggle the card reader; if it moves or feels loose, it could be a skimmer. The device’s design elements, like arrows or lines, might not align correctly with the pump. Comparing the card reader at your pump to those on adjacent pumps can also reveal discrepancies.
Recognizing Internal Skimmers
Internal skimmers are more challenging to detect as they are hidden inside the gas pump’s secure compartment and are not directly visible. Consumers should focus on indirect clues that suggest the pump has been compromised. A loose or wobbly card reader, even if it appears normal, can indicate internal tampering.
The keypad used for entering your Personal Identification Number (PIN) is another sign. If the keypad feels different, is raised, or does not match the appearance of keypads on other pumps, it could be a fake overlay. Covering the keypad with your hand while typing is a prudent measure, as criminals may install tiny, hidden cameras to record PIN entries.
Spotting Other Signs of Tampering
Beyond the card reader, other signs of tampering on a gas pump can indicate a skimmer or other illicit modifications. Many gas pumps feature security seals, often tamper-evident labels, placed over access doors or panels. These seals are designed to break or display a “VOID” message if someone attempts to open the pump without authorization.
Check if these security seals are broken, torn, peeling, or replaced with non-matching tape. The pump’s cabinet doors should be securely closed and fit flush; any signs of forced entry, such as pry marks or doors that are ajar, are red flags. Comparing the security seals and panel alignment with neighboring pumps can help identify inconsistencies.
Steps to Take if You Suspect a Skimmer
If you encounter a gas pump that shows signs of a skimmer or tampering, avoid using that pump. Do not insert your card or attempt to complete a transaction. Immediately report your suspicions to the gas station attendant or manager, providing specific details about what you observed.
Contact local law enforcement via their non-emergency line to report the potential crime. For payment, consider paying inside the station with an attendant, using a mobile payment option like Apple Pay or Google Pay, or choosing a different gas station. Using a credit card rather than a debit card for transactions at the pump offers better fraud protection, as it limits direct access to your bank account. Regularly monitor your bank and credit card statements for any unauthorized transactions and report suspicious activity to your financial institution without delay.
