A small length of magnetic tape adhered to credit cards, badges, permits, passes and tokens. The tape is read by magnetic stripe readers incorporated into ATMs, identification readers and payment terminals. Due to the daily, heavy wear these cards receive, the digital recording on the stripe is in a very low-density format and often duplicated several times in case part of the stripe becomes damaged.
