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

The invention provides a card reader which can proof steal by generating interference magnetic field with an interference magnetic field generation mechanism, and can proporly detect an external connection terminal by a metal detcting mechanism. A card reader may include 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 a card with an IC chip built-in and a magnetic stripe formed. Moreover, the present invention also relates to a control method of the card reader. Background technique [0002] Conventionally, card readers that read magnetic data recorded on a card and record magnetic data on a card have been widely used. In industries such as financial institutions that use card readers, in the past, criminals installed a magnetic head on the card insertion portion of the card reader and used the magnetic head to improperly obtain the magnetic data of the card, that is, card theft became a major problem. Therefore, it has been proposed to use a card reader that generates a disturbing magnetic field for preventing magnetic data from being read by a magnetic head for stealing a card (hereinafter referred to as a "magnetic head for stealing a card") (for example, refer to Patent Document 1). The card reader described in ...
