By capturing the data contained on the magnetic-stripe of a legitimate card, criminals either encode a counterfeit card or re-encode a lost or stolen card. When an electronic authorization attempt is made with the encoded or re-encoded card, it can result in an issuer approval of a fraudulent transaction. To prevent skimming, you should be on the lookout for:
- Anyone operating an electronic device not normally used in your day-to-day business activities.
- Anyone offering you money to record account information.
- Apparent tampering with the in-store point-of-sale devices (scratches, color changes, devices attached to point-of-sale (POS) cables, etc.)
Ensure that card data is protected in accordance with the PCI DSS requirements at all times. If you suspect skimming activity is happening at your place of business, contact us immediately.
By keeping your equipment safe and your staff trained — and by knowing what to do if there’s a problem — you can prevent your business from falling prey to criminals out to steal payment card data and PINs from POS terminals. Consider applying some of these key best practices to prevent thieves from tampering from your POS terminals.
- Track and monitor all POS terminals
- Check for simple abnormalities. A missing seal or screw, or extra wiring or holes, for instance — could be the first step to uncovering fraud. You should also look out for added labels, decals or other materials that may be masking damage inflicted by tampering.
- Routinely inspect POS terminals and secure them as to prevent removal. Connector cables should also be safeguarded. Whenever possible, protect them by using a conduit, or contain them within a secure structure.
