Credit card skimming is a form of theft where criminals use a small device to steal credit card information during an otherwise legitimate transaction. Once the information is captured, it can be duplicated onto blank cards or used for unauthorized online transactions. As this type of fraud continues to evolve, it's essential for consumers to be informed and vigilant. This article explores how to avoid falling prey to skimmers and how to identify them.
What is a credit card skimmer?
A credit card skimmer is a device designed to capture the magnetic stripe information from a credit or debit card. These devices are often discreet and difficult to spot, as they're installed directly over the card reader of ATMs, gas station pumps, and other machines where card transactions occur.
How to Spot a Skimmer?
- Check for Physical Anomalies: Before inserting your card, examine the card reader closely. If it looks different from others or appears to have an additional piece attached, be wary. Also, give the card reader a gentle tug. Genuine card slots won't come off easily, but skimmers might.
- Mismatched Graphics or Colors: some cases, skimmers might not match the color or design of the original terminal. If something seems out of place, reconsider using the machine.
- Keypad Feels Different: Some skimmers come with a fake keypad overlay. If pressing the keys feels different than usual, like they're too thick or spongy, it could be a sign of tampering.
- Check Nearby Cameras: Skimmers sometimes work in conjunction with tiny cameras meant to record PIN entries. Look around for small holes or objects that seem out of place, as these might hide a camera.
How to Avoid Skimming?
- Use ATMs Inside Banks: Machines inside banks are generally safer because they're less accessible to criminals than standalone ATMs.
- Shield Your PIN: Always use your hand or body to shield your PIN as you enter it, in case there's a hidden camera.
- Regularly Monitor Bank Statements: Routinely check your bank and credit card statements for any unauthorized transactions. Early detection can limit potential damage.
- Use EMV Chip Cards: Skimmers target the magnetic stripe on cards. EMV chip cards, however, generate a unique code for every transaction, making duplicated card info less valuable to thieves.
- Avoid Using Card at Suspicious Terminals: If something seems off about a terminal, trust your instincts and pay with cash or use another machine.
- Update Card Payment Apps: Mobile payment apps, like Apple Pay or Google Pay, use tokenization, which provides an added layer of security against skimming.
What to Do If You Spot a Skimmer?
- Do Not Use the Machine: Avoid inserting your card.
- Alert the Authorities: Inform the local police and the business owner. They can inspect the machine and take appropriate action.
- Inform Your Bank: If you've used a compromised machine, contact your bank immediately to inform them and get advice on the next steps.
While credit card skimmers are a significant concern, awareness and vigilance are key. By routinely inspecting card terminals, protecting your PIN, and monitoring your bank statements, you can reduce your risk and ensure that your financial information remains secure.
