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.
