Understanding how skimmers work and how to spot them can help protect both your business and your customers.

What Exactly Is a Payment Card Skimmer?

A payment card skimmer is a small, unauthorized device criminals attach to or install inside payment terminals, ATMs, and point‑of‑sale (POS) systems. These devices are designed to capture card data during a transaction—such as the card number and sometimes PIN information—which can later be used to commit fraud.

Skimmers come in different forms, including:

• External attachments that fit over card readers or keypads
• Internal components hidden inside the terminal
• Overlay devices that sit on top of existing hardware to mimic the original equipment

Because many of these devices are engineered to blend in, spotting them often requires a closer look.

How to Spot Signs of Tampering

While skimmers can be subtle, there are noticeable clues that something may be off. Keep an eye out for the following:

• Card readers or keypads that seem loose, bulky, or misaligned
• Parts that look different from other terminals of the same model
• Broken or missing security seals, panels, or stickers
• Terminals behaving unusually, freezing, or functioning differently than normal

If a device looks or feels “different” from what you’re used to, it’s worth taking a moment to inspect further.

Simple Steps to Keep Your Payment Devices Secure

Staying proactive doesn’t require specialized training. A few routine practices can significantly reduce the risk of tampering:

• Inspect devices regularly for physical changes or damage
• Limit access to payment terminals to authorized staff only
• Report anything suspicious immediately to info@goebt.com
• Keep a reference photo or record of how your devices normally look for quick comparison

Prompt reporting helps protect both your business and your customers, preventing potential financial and operational disruption.

Keeping Security a Shared Priority

Fraud prevention is most effective when businesses and staff stay attentive. By staying familiar with how your equipment should look and operate, you’re already taking one of the most important steps toward safeguarding your point‑of‑sale environment.
