Magnetic strip cards are capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the cards. The magnetic strip, sometimes called a magstripe, is read by physical contact and swiping past a reading head. Magnetic strip cards are commonly used in credit cards, identity cards and transportation tickets. A number of International Organization for Standardization (ISO) standards define the physical properties of the card, including size, flexibility, location of the magstripe and magnetic characteristics. They also provide the standards for financial cards, including the allocation of card number ranges to different card issuing institutions.

In most magnetic strip cards, the magnetic strip is contained in a plastic-like film. The magnetic strip is located 0.223 inches (5.66 mm) from the edge of the card, and is 0.375 inches (9.52 mm) wide. The magnetic strip contains three tracks, each 0.110 inches (2.79 mm) wide. Tracks one and three are typically recorded at 210 bits per inch (8.27 bits per mm), while track two typically has a recording density of 75 bits per inch (2.95 bits per mm).

Magnetic strip cards following these specifications can typically be read by most point-of-sale hardware, which are simply typical computers that can be programmed to perform specific tasks. Examples of cards adhering to these standards include ATM cards, bank cards, credit and debit cards, gift cards, loyalty cards, membership cards and nearly any application in which value or secure information is not stored on the card itself. Many video game and amusement centers now use debit card systems based on magnetic stripe cards.
