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.

摘要： The present invention is applicable to the field of POS machines, and provides a hidden wireless swiping device used in a POS machine and a POS machine using the hidden wireless swiping device. The hidden wireless swiping device comprises a circuit board, a wireless module, a light transmission plate configured to cover the wireless module, and an indicator light mounted on the circuit board; at least one surface of the light transmission plate is a frosted surface, and the circuit board is provided thereon with a control circuit configured to control the wireless module and the indicator light to operate. In the hidden wireless swiping device, the light transmission plate of which one surface is arranged to be a frosted surface covers on the wireless module, the indicator light is arranged on the circuit board, and the control circuit is arranged on the circuit board to control the wireless module and the indicator light to be turned on/off and to operate. When the indicator light stops operating, since one surface of the light transmission plate is the frosted surface, it is difficult to see structures in the POS machine through the light transmission plate, and thus invisibility is realized. When the wireless module needs to be used, as long as the wireless module and the indicator light are controlled by the control circuit to operate, the wireless module can be enabled to operate.
