CARD READER FOR AN AUTOMATED TELLER MACHINE, AND CONTROL METHOD FOR SAME

摘要

The present invention relates to a card reader for an automated teller machine, and to a control method for same. More particularly, the present invention relates to a card reader for an automated teller machine, and to a control method therefor, wherein the card reader has a shutter arranged at a card insertion slot to control the opening/shutting operations of a passageway, and the shutter intermittently repeats the opening/shutting operations when a card is inserted via the card insertion slot to enable the card which is inserted via the card insertion slot to intermittently move, such that the inserted card moves along an irregular pattern within the card reader and also vibrates, thus preventing information recorded on the card from being read and compromised by a skimming device which might be illegally installed in the card insertion slot of the card reader. The method for controlling a card reader of an automated teller machine according to the present invention comprises the following steps: opening a shutter arranged at a card insertion slot and leading a card into the card reader using a card transfer roller, when the insertion of the card into the card insertion slot is sensed; operating a shutter-driving unit in accordance with a preset pattern to intermittently repeat the opening/shutting operations of the shutter arranged at the card insertion slot, when the card starts being transferred into the card reader; and stopping the operation of the shutter driving unit upon the completion of transferring the card into the card reader. As described above, the shutter repeats opening/shutting operations during the processes of inserting the card into the card insertion slot and transferring the card into the card reader to enable the card which is inserted into the card insertion slot to intermittently move.
