Abstract

A magnetic stripe (MS) card anti-hacking device provided in a financial service apparatus including an MS card reader includes a sensor detecting whether an abnormal attachment is attached to a card insertion portion of the MS card reader, a sensor controller determining whether the abnormal attachment is attached to the card insertion portion by processing a signal received from the sensor, an anti-skimming (jamming) driver generating a jamming signal to interfere with replication of an MS card when the abnormal attachment is attached to the card insertion portion, and a jamming signal output portion radiating the jamming signal toward the abnormal attachment.

Claims

1. A magnetic stripe (MS) card anti-hacking device provided in a financial service apparatus including an MS card reader, the MS card anti-hacking device comprising:

a sensor detecting whether an abnormal attachment is attached to a card insertion portion of the MS card reader;

a sensor controller determining whether the abnormal attachment is attached to the card insertion portion by processing a signal received from the sensor;

an anti-skimming (jamming) driver generating a jamming signal to interfere with replication of an MS card when the abnormal attachment is attached to the card insertion portion; and

a jamming signal output portion radiating the jamming signal toward the abnormal attachment.

2. The device of claim 1, wherein the jamming signal output portion comprises an induction coil for outputting the jamming signal as a magnetic field.

3. The device of claim 2, further comprising a warning portion warning attachment of an abnormal attachment when the abnormal attachment is attached to the card insertion portion.

4. The device of claim 1, further comprising a warning portion warning attachment of an abnormal attachment when the abnormal attachment is attached to the card insertion portion.

5. The device of claim 4, wherein the warning portion comprises at least one of a vibration warning portion including a vibration motor, a visual warning portion including a light emission lamp, and an auditory warning portion including a buzzer.

6. The device of claim 2, wherein the warning portion comprises at least one of a vibration warning portion including a vibration motor, a visual warning portion including a light emission lamp, and an auditory warning portion including a buzzer.

7. A magnetic stripe (MS) card anti-hacking method comprising:

determining whether a card hacking device for replicating an MS card is attached to a financial service apparatus in which the MS card is used; and

preventing replication of the MS card by the card hacking device by generating a jamming signal when the card hacking device is determined to be attached to the financial service apparatus.

8. The method of claim 7, wherein the jamming signal is a magnetic field signal generated by a magnetic induction coil.

9. The method of claim 8, wherein, when the card hacking device is connected to the financial service apparatus, a warning portion generates a warning signal.

10. The method of claim 7, wherein, when the card hacking device is attached to the financial service apparatus, a warning portion generates a warning signal.
