Problems solved by technology

However, in the card reader described in Patent Document 2, if the disturbance magnetic field generating mechanism is arranged in the card insertion portion, there is a concern that the detection coil of the metal sensor will be damaged under the influence of the disturbance magnetic field generated by the disturbance magnetic field generating mechanism. The output fluctuates, and the metal sensor cannot perform proper detection of the external connection terminal.

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.

Description

technical field [0001] The invention relates to a card reader for processing cards with built-in IC chips and formed with magnetic stripes. Moreover, the present invention also relates to a control method of the card reader. Background technique [0002] Conventionally, a card reader for reading magnetic data recorded on a card and recording magnetic data on the card has been widely used. In industries such as financial institutions that use card readers, criminals have conventionally attached a magnetic head to the card insertion portion of the card reader and used the magnetic head to illegally obtain magnetic data of the card, that is, card theft has become a major problem. Therefore, it has been proposed to use a card reader that generates a disturbing magnetic field for preventing reading of magnetic data by a magnetic head for card theft (hereinafter referred to as a "card theft magnetic head") (for example, refer to Patent Document 1). The card reader described in P...
