POS (Point of sales terminal) is a Chinese meaning of "point of sale", which is called point of sale information management system, and has cash or barter function. With the progress of the times and the development of payment technologies, card swiping consumption by adopting a POS machine becomes a trend. For high-tech POS and the like, the information security requirements for customers are quite high. Generally, products cannot be disassembled, and if a user needs to disassemble the products, the users want to crack confidential information and need to be capable of preventing the disassembly and protecting the circuit.

Therefore, it becomes unnecessary to provide a POS tamper-resistant structure to provide a secure card-swiping consumer environment for the consumer. For the POS, the areas that need to be protected mainly are: the device comprises keys, a liquid crystal screen, a core control area, an IC card seat, a magnetic head, a main board, a front shell, a protective board and a rear shell. The industry currently uses tamper-resistant safety contacts to protect the inner circuitry. However, these conventional tamper-proof designs have certain drawbacks and can only be applied to circuits of a general security level. When the POS machine is damaged (such as being dismantled) to the outside, the trigger protection program of the anti-dismantling safety contact can not be executed, and the data information of the user is in danger of leakage.

The utility model discloses a utility model patent with the grant bulletin number of CN205176993U discloses a POS machine anti-disassembly protection structure, and the anti-disassembly protection structure comprises a POS machine shell, a PCB board, a conductive silica gel contact and a safety contact, wherein the safety contact is positioned on the PCB board, the conductive silica gel contact is positioned on the POS machine shell, the safety contact is contacted with the conductive silica gel contact to form a safety switch, and the safety switch is pressed by the POS machine shell to be in a normally closed state; still include Mesh line wallboard, Mesh line wallboard is located the PCB board, Mesh line wallboard is surrounding the safety contact. When the side surface of the POS machine is attacked by the outside, the lead inside the Mesh wire wallboard is damaged, and then the internal circuit of the POS machine triggers the safety protection device of the POS machine, so that the leakage of related data information of the POS machine is prevented; meanwhile, the Mesh wire wall plate is arranged on the side face, so that one layer of protection is generated on the safety contact, the safety contact is prevented from being damaged, the protection strength of the safety switch is enhanced, the safety performance is enhanced, and the safety of user data is guaranteed.
