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

摘要

A magnetic head protection frame used in a POS machine, a card swiping module using the magnetic head protection frame, and the POS machine using the card swiping module. The magnetic head protection frame (50) comprises a supporting frame (51), the supporting frame (51) being in a long strip shape; a first opening (511) exposing a magnetic head (41) is provided on the supporting frame (51); a circuit board (52) is arranged on the outer surface of the supporting frame (51); the circuit board (52) is arranged along the whole length direction of the supporting frame (51); and the circuit board (52) bypasses a position corresponding to the first opening (511) and is connected to a leading wire (53). By arranging a circuit board (52) on the outer surface of a supporting frame (51), an alarm signal can be triggered because the circuit board (52) can be switched off or in a short circuit when suffering from a physical attack, and a safety processor on a main board of a POS machine (100) can be further triggered to wipe or destroy information stored on electronic elements in a protection zone, thereby achieving the function of preventing user information from being stolen, and protecting a magnetic head (41) for safely reading information about a card.
