Magnetic stripe card anti-theft information-reading jammer and magnetic card swiping equipment

Abstract

The invention provides a magnetic stripe card anti-theft information reading jammer and magnetic card swiping equipment. The magnetic stripe card anti-theft information interference unit comprises a signal generation module, a radio frequency control module electrically connected with the signal generation module and an electromagnetic wave transmitting module electrically connected with the radiofrequency control module. During working, the signal generation module generates an initial interference signal and transmits the initial interference signal to the radio frequency control module; the radio frequency control module processes the initial interference signal to generate an output interference signal and transmits the output interference signal to the electromagnetic wave transmitting module, and the electromagnetic wave transmitting module generates and transmits a steal-read interference electromagnetic wave according to the output interference signal, so that the magnetic card steal-swiping device can be interfered, and the safety of the magnetic card swiping process is improved.

Description

technical field [0001] The invention relates to the technical field of magnetic card equipment, in particular to a magnetic stripe card anti-theft reading information jammer and a magnetic card swiping device. Background technique [0002] A magnetic card is a card-shaped magnetic recording medium that uses magnetic carriers to record character and digital information for identification or other purposes. Magnetic cards are made of high-strength, high-temperature-resistant plastic or paper-coated plastic, and magnetic strips are set on them, which are extremely versatile. Common bank cards are made of magnetic cards. [0003] The existing magnetic card needs to be matched with the recording head for recording operation. Specifically, current is applied to the coil of the recording head, and the magnetic surface of the recording head and the magnetic card are relatively moved. At this time, the magnetic head will generate a magnetic field in the gap between it and the magneti...

Problems solved by technology

[0005] Because the magnetic card is made of plastic with magnetic strips, it has the advantages of moisture-proof, wear-resistant, good flexibility, easy to carry, easy to read and write, and low cost. However, limited by its working principle, the safety of the magnetic card is poor. , see figure 1 , when using the magnetic card 200 on the magnetic card swiping device 100, if an illegal person places the fraudulent swiping device 300 at the magnetic card entrance 110 of the magnetic card swiping device 100, then the magnetic card 200 is inserted into the card slot 120 in the magnetic card swiping device 100 by the magnetic card entrance 110 During the process, the fraudulent brushing device 300 will illegally steal the information recorded on the magnetic card 200, which will bring very large losses to the user of the magnetic card.
