Abstract
A card reader may include a card insertion port; a magnetoresistive (MR) sensor; and a disturbing magnetic field generator, wherein the card may include a magnetic stripe, and magnetic data recorded in the magnetic stripe may be arranged in a moving direction of the card inserted through the card insertion port. The MR sensor may include a first resistor and a second resistor separated by a distance which is less than a bit interval of magnetic data, in a case that '0' data are recorded in the magnetic stripe, in the moving direction of the card.
