Mobile phone lock screen is a communication travel card. What happened?

Many users' mobile phones inexplicably received the verification code of Communication travel itinerary, but they obviously didn't use it. I don't know why they received it. This article talks about the related reasons.

The mobile phone inexplicably received the verification code of the communication travel card. What is the reason?

The answer is "caused by other users' misoperation". Because the registration and login of the communication travel card only need to use the mobile phone number to receive the verification code, and the mobile phone numbers used by domestic users are provided by the three major communication operators, this will happen if other users fill in the wrong mobile phone number when registering or logging in the communication travel card.

Could it be that someone registered maliciously?

The answer is "this possibility is not ruled out", but the crux of the problem is what is the purpose of malicious registration. Based on the needs of epidemic prevention and control, all provinces, cities and counties in China have set up relevant communication travel cards in their jurisdictions to help people do a good job in epidemic prevention. The travel card does not contain too much information, mainly to show the user's behavior track, even if someone maliciously registers, it can't be used to do things that violate the law and discipline. Moreover, both the mobile phone number and the boarding code are real-name registration systems, and there is a special person to review the scenes that need to be used, which can almost rule out the possibility of malicious registration by others.

What information does the trip code contain?

Behind the travel itinerary code is big data. Due to the restrictions of domestic laws and regulations, the apps used by users must be real names, such as WeChat or Alipay. The main carriers of travel codes are WeChat applets, Alipay applets, WeChat official accounts, and independent apps, applets and WeChat official accounts, which contain very little personal privacy information. Users only need their mobile phone number and verification code to register and log in. It contains the user's behavior track and some personal information (all semi-hidden) and is stored in a special server. Generally speaking, this information cannot be tampered with. If you are an insider, you don't need a verification code at all. If it is an external person, even after obtaining the verification code, there is not much information displayed, which is almost useless.

Conclusion: If you receive the verification code occasionally, you don't have to pay attention to it. As long as you don't receive verification codes often, there is no problem. If you often receive the verification code, you can call the customer service phone of your own communication operator and ask the other party to help you check and solve it.
