How does travel itinerary Code know where you have been?

By analyzing the signaling data and bill data of the mobile phone, the travel code can judge which city base station you have contacted, so as to know where you have been.

With the rapid development of social economy, everyone is enjoying the changes brought by science and technology to our lives. Travel code can better cooperate with epidemic prevention and control and avoid other problems. As ordinary people, we must actively cooperate with epidemic prevention and control staff in our lives to make our lives better.

1. What's the travel code?

The itinerary code is a public welfare itinerary inquiry service jointly launched by China ICT Institute, China Telecom, China Mobile and China Unicom under the guidance of the Ministry of Industry and Information Technology. At first, it was only possible to query by SMS, and later it was upgraded to scan code query. With the continuous spread of the epidemic, the scope of travel itinerary code has become a nationwide system. The introduction of run-length encoding is also to better grasp everyone's itinerary and avoid the spread of the epidemic. I hope that everyone will actively cooperate with the epidemic staff in their lives to carry out relevant investigations to avoid it.

2. What is the working principle of trip code?

With the rapid development of social economy, people use digital products such as mobile phones and computers more and more widely. In the process of using mobile phones and computers, whether it is communication, texting or surfing the Internet, you need to connect to the relevant base stations. The specific information operators of each base station are very clear. Therefore, in the process of using mobile phones and computers to generate communication in our lives, operators will also record data and upload them to the run-length encoding system. We only need to scan the code to see the places we have been in the last 14 days. This is also the case.

3. How to use the trip code correctly?

In life, if there is a misjudgment of the trip code, we must treat it rationally. It is important to pay attention to freshmen. Not every city has a recording system, but it depends on how long you stay in the local area for 4 hours. Therefore, we must explain to the epidemic prevention and control personnel in time in our lives to avoid adverse effects on our lives.
