MAGNETIC HEAD PROTECTION FRAME, CARD SWIPING MODULE, AND POS MACHINE

摘要

The present invention is applicable to the field of POS machines, and provides a magnetic head protection frame used in a POS machine, a card swiping module using the magnetic head protection frame, and a POS machine using the card swiping module. The magnetic head protection frame comprises a support frame, the support frame is strip-shaped, and the support frame defines a first opening exposing the magnetic head; a circuit board is mounted on an outside surface of the support frame, the circuit board is arranged along the whole length direction of the support frame, and the circuit board avoids a position corresponding to the first opening; connecting wires are connected on the circuit board. By arranging the circuit board on the outside surface of the support frame, since the circuit board will be open-circuited or short-circuited when it is subjected to a physical attack, an alarming signal will be triggered, and thus a security processor on a main board of the POS machine can be triggered, such that information stored in electronic components in a protected area is erased or destroyed, the function of preventing user information from being stolen is achieved, and the magnetic head is protected so as to read card information safely.
