Abstract
A card reader may include a card insertion slot into which the card is inserted; a metal detecting mechanism structured to detect the external connection terminal of the card inserted into the card insertion slot; a jamming magnetic field generation mechanism structured to generate a magnetic field for prevention of fraudulently reading a magnetic datum recorded in the magnetic stripe; and a control unit. The metal detecting mechanism may include an exciting coil and a detecting coil. The jamming magnetic field generation mechanism may include a jamming magnetic field generating coil. The control unit may be structured to alternately switch between a current supply to the exciting coil and a current supply to the jamming magnetic field generation coil, and detect the external connection terminal on the basis of an output from the detecting coil at a time when the exciting coil is supplied with a current.
