[0002] A POS machine reads the cardholder's magnetic stripe information on a bank card through a card reader. After the operator enters the transaction amount and the cardholder enters personal identification information, the POS machine sends this information to the issuing bank system through the UnionPay center to complete an online transaction, gives information on whether the transaction is successful or not, and prints the corresponding receipt. The application of the POS machine realizes the online consumption of bank cards such as credit cards and debit cards, ensures the safety, speed and accuracy of transactions, avoids complicated labor such as manually querying the exception list and pressing receipts, and improves work efficiency.

[0003] A POS machine financial encryption product is an encryption device used for protecting financial transaction data. Through a variety of cryptographic algorithms and hardware security measures, it ensures the security and integrity of financial transaction data. The device should be anti-disassembled to prevent data leakage or tampering.

[0004] In the prior art, the anti-disassembly of a POS machine financial encryption product generally uses MESH FPC to bond to the backlight surface of the screen for anti-disassembly. MESH FPC is a flexible printed circuit board with anti-disassembly line function and can be used to protect customer information security. MESH FPC is bonded to the back of the display screen, which can effectively prevent the module from being illegally disassembled and protect the internal important circuits and data from being leaked. However, when the display screen is heated at a high temperature, the MESH double-sided tape fails and the screen can be removed.

[0005] Therefore, it is necessary to provide an anti-disassembly structure that can effectively prevent disassembly and has a simple structure and process. Summary of the Invention
