| | Magnetic stripe card - Wikipedia, the free encyclopedia |
 | | 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. |
 | | A number of International Organization for Standardization standards, ISO 7810, ISO 7811, ISO 7812, ISO 7813, and ISO 4909, define the physical properties of the card, including size, flexibility, location of the magstripe, and magnetic characteristics. |
 | | The card may have metal contacts connecting the card physically to the reader, while contactless cards use a magnetic field or radio frequency (RFID) for proximity reading. |
