A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. ... Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets. The first and second tracks in the magnetic stripe are encoded with information about the cardholder's account, such as their credit card number, full name, the card's expiration date and the country code. Additional information can be stored in the third track.
