Abstract

A magnetic reader which does not allow magnetic information recorded on a magnetic recording medium to be stolen by an illicit magnetic reader is provided. The magnetic reader includes: a foreign object detection section 10 which determines whether there is a foreign object near a card slot 22 through which a magnetic card 21 is inserted or taken out; a magnetic field generation section 8 which generates a disturbing magnetic field in a vicinity of the card slot 21 for disturbing a magnetic field radiated from a foreign object if present near the card slot 22; and a control section 9, 11 which determines whether the foreign object detection section 10 has detected a foreign object and which, when the foreign object detection section 10 determines to have detected a foreign object, changes the strength of the disturbing magnetic field generated by the magnetic field generation section 8.

Description

technical field [0001] The invention relates to a magnetic reading device, which has the function of preventing illegal reading of magnetic data of a magnetic information recording medium, and reads the magnetic data of the magnetic information recording medium. Background technique [0002] There is the following crime A called skimming: cash transaction processing devices such as automatic teller machines (hereinafter referred to as CD (Cash Dispenser)) and cash automatic teller machines (hereinafter referred to as ATM (Automated Teller Machine)), and In a transaction processing terminal that utilizes a card or passbook or other media that has recorded magnetic information for transaction processing, an illegal magnetic reading device equipped with a magnetic head is set to cover the insertion port of the magnetic information recording medium of the original magnetic reading device. to obtain the magnetic information of the magnetic stripe. As its countermeasures, various...
