A credit card skimmer is a device that is used to steal credit card information. It is typically attached to a payment terminal and reads the magnetic stripe on the back of the card. The information is then stored on the skimmer and can be retrieved later by the thief.
Credit card skimmers are a major problem for businesses and consumers alike. Businesses can lose money from fraudulent charges, and consumers can have their identities stolen. In some cases, credit card skimmers can even be used to steal PIN numbers.
