Card cloning, also known as skimming, is a form of credit or debit card fraud where someone copies the information from the magnetic stripe of a card without the cardholder's permission - Also applicable to security technologies!! This is usually done with a small device known as a skimmer that can be secretly installed on ATMs, gas station pumps, or other card readers. When a card is swiped through a skimmer, the device captures and stores all the details stored on the card's magnetic stripe, including the card number, expiration date, and cardholder’s name.
The thief can then use this stolen information to create a duplicate or “clone” of the original card.
