What is card skimming?
Card skimming is a crime. Criminals use sophisticated skimming techniques to steal or skim data from a customer’s card when it’s processed through a merchant terminal. A more experienced criminal will try to get a customer’s PIN at the same time. Once they have this information, criminals use the stolen data to create fake cards and withdraw funds at ATMs.
How are cards skimmed?
A merchant terminal does not save a customer’s card or PIN. To skim cards in your store, a criminal would need to steal your terminal, make changes to it, and put it back, or swap your terminal with one they have already modified. Either way, they need access to your terminal, so it’s important to guard it like you would cash.
How do I safeguard against skimming?
You can reduce the risk of skimming by checking your merchant terminal daily to ensure it:
- Looks the same as before and has no damage
- Has the same type and number of cables
- Has the correct serial number
- Prints receipts with the right business name and address
- Is clear of any hidden camera.

What is card testing?
Card Testing happens when third parties try to use your business website to determine if stolen credit card details are valid. Criminals will test small value payments using stolen credit card details to determine if a transaction will be approved using those details. The approved cards are then used to defraud another merchant for a larger amount.
