Abstract
A card reader for processing an inserted magnetic card may be equipped with a front sensor arranged in the vicinity of an insertion opening for a magnetic card to detect the insertion of the magnetic card, a rear sensor for detecting the magnetic card when the magnetic card is fully inserted, a magnetic field generating unit for generating a magnetic field in the vicinity of the insertion opening for a magnetic card, and a control unit for controlling a magnetic field to be generated by said magnetic field generating unit at a first strength or at a second strength weaker than the first strength. The control unit may control the strength of the magnetic field to be generated by the magnetic field generating unit at the second strength while the first time period elapses after the rear sensor has detected the magnetic card and then has stopped sensing it.
