How to prevent the QR code from being maliciously switched?

Although the link of mobile payment is quite simple, the security problem cannot be ignored. Some criminals just caught the funnel and set a "trap" for everyone. If you like to use mobile payment, you need to be extra careful. Recently, Ms. Yang, a street vendor in Jingjiang City, encountered a "trap" and all the turnover in one afternoon was cheated. The reason is that the QR code of the merchant has been "maliciously" exchanged.

1 For merchants, the QR code should be kept well. When hanging, put the QR code in the field of vision that they can monitor. Don't post it at will, try to keep it in plastic packaging. Or take it out when you want to use it to avoid being stolen by others. Recently, there is also a media report on the QR code of the payment ticket: the scammer forged the "Illegal Parking Notice" of the traffic control department, let the owner scan the code to pay, and then swindle money. For the public, the QR code of unknown origin should not be easily scanned to avoid unnecessary economic losses.

It is best to buy and pay in the online mall of the store and spend offline. This can eliminate and avoid the above security problems. Shopkeepers can use the fish collection platform to display and promote their products. Paying through online stores eliminates the risk of being replaced by "good people". Moreover, it can also rely on the tens of millions of exposure advantages of the platform to carry out targeted publicity and achieve precise marketing. . Consumers buy and place orders through the fish collection platform, and they don't have to worry about inputting unfamiliar pictures when they consume, resulting in financial losses.

Therefore, for merchants, they must be optimistic about their QR code and put it in the field of vision that they can monitor. Don't stick it casually, try to keep it in plastic packaging. Or take it out when you want to use it to avoid being stolen by others.
