As an electronic payment product, UnionPay card swiping machine often has some problems in the process of swiping cards, which brings security risks to cardholders. Now there are more and more personal POS machines, and there are many POS machine brands on the market. POS machines will never be handled because of hobbies, but because of needs. The security of POS machine is definitely not a reference for selection, but it is absolutely important. Because it is directly related to the security of users' funds, we should fully understand the security of POS machines and the potential risks that may be encountered in the process of handling them.

If you want to apply for a personal POS machine, you need to pay attention to the flow of account funds and distinguish between one sorter and two sorters. After the conventional sorter is completed, its daily operation and transaction data will be supervised by the central bank and China UnionPay. Because the informal clearing machine is not in the sight of supervision, there may be delays or no accounts at all. It is illegal to operate the second cleaning machine, which is prone to code skipping and other risks. The direct harm of code skipping to cardholders is that credit cards are blocked, and there may be risks such as accumulated points and stolen funds.

Now when handling POS machines, some payment institutions need to submit them to agents before they can be opened. It is suggested that when submitting such information, the image can be watermarked to ensure that the information will not be used for other purposes. After all, the threshold of POS agent is very low now, and all kinds of people can reach it. Watermark is more secure. I believe that many people have credit cards, and those who have credit cards will certainly understand the greatest use of POS machines, which can completely replace the perfect solution to the turnover problem. From the credit card bill to the repayment date, you can use the POS machine to settle the bill, and the merchant can pay the bill.
