Taking out the mobile phone card just disconnects. There are two methods for positioning, one is the positioning of dedicated GPS module, and the other is the positioning of base station based on service provider.
The travel track of the travel card cannot be cleared, but it will be updated every 14 days. For us ordinary people, as long as we pay attention to avoid going to high-risk areas, we don't have to worry too much about protecting our own safety.
Insist on the importance of scanning "double code"
"Please scan the code to register." Recently, many citizens have reported that it is relatively simple to take their temperature and wear masks, but it is quite troublesome to scan the "health code" and "boarding code" every time they enter public places such as communities, hospitals, stations and restaurants.
"It is very necessary to scan the double code." In this regard, Chen Zhijun said that the "health code" is like a citizen's electronic identity QR code, providing citizens with convenient digital travel vouchers. The color of the "health code" reflects my current health status during the epidemic and whether there is a risk of infection.
The "Travel Code" can query all the city information visited in 14 days with one click, and intuitively understand whether citizens have been to the city where the high-risk area is located and whether they belong to the risk group. Help to prove personal travel trajectory, and then effectively take corresponding epidemic prevention measures.
"Simply put, the' health code' is used to reflect the health status of citizens during the epidemic, while the' travel code' is used to prove whether citizens have been to the city where high-risk areas are located within a certain period of time." Chen Zhijun said that promoting the use of "health code" and "trip code" is an important information means for refined epidemic prevention and control, and it is also an important technical means to improve the efficiency of epidemic control in normalized prevention and control.
