Nowadays, with the rapid development of Chinese society, various levels of technology have been widely used in the daily life of the public, which has changed our traditional life style. Among them, WeChat and Alipay have become the most important payment channels. In the past, everyone had to bring cash when going out to the supermarket. Shopping is not only a long queue at the checkout, but also a lot of change is a headache. When mobile payment appears, you don’t need to bring cash. Not only can you avoid receiving change, but you don’t have to carry your wallet to worry about money and property being stolen. From these aspects, there are indeed many benefits. But everything has two sides. Putting money on the Internet is afraid of encountering black technology. For example, many people worry that the payment will be successful without entering the password when shopping. Will it be unsafe?

Today I will introduce the mechanism of this code scanning gun. The code scanning gun in the hands of merchants is officially provided by Alipay and WeChat, so in essence, it is the same as the credit card machine. It is very troublesome to get this small code scanning gun. Merchants must first apply for a QR code scanning gun, which can only be obtained after passing successive approvals. However, if there is a need, relevant staff will come to the door to provide services. There is a limit on the amount of the QR code scanning gun, and a single payment cannot exceed 1,000 yuan. . When paying, the user only needs to open the QR code to complete the payment. Although it is fast, some users wonder how the money can go out without entering the password?

The development level of modern society is already very high, but the means of various scammers are also advancing with the times, and it is impossible to prevent it. It is normal for consumers to have questions. Many people worry that if someone deliberately scans their payment code, it will be troublesome if it is stolen. Here is a small I want to remind you that it is purely overthinking. The QR code is different when paying. The payment code on the user's mobile phone is time-sensitive. Sometimes it will prompt that it has expired if it takes too long. The safety of the user's funds is guaranteed to the greatest extent, but the payment code is fixed, so there is no need to worry about being swept away by others, unless the user makes a mistake, you must see it clearly!

What we need to pay attention to now is the function of password-free payment. Most people have already opened password-free payment, and they can also pay without a payment password. Recently, many mobile phones have been stolen. The problem lies in the password-free payment. Although Alipay and WeChat The official stated that it will give users appropriate compensation, but that compensation and loss is simply a drop in the bucket. To be on the safe side, it is better to turn off password-free payment in the recent period.

Now that smart phones are very common, the software in mobile phones has become the main means of mass entertainment, such as games, videos and other apps. These apps will have some password-free payment options. When this opportunity comes, small amounts of money will be transferred away if they add up. Therefore, you must check the terms clearly when paying for the software to avoid losses.
