Is there a record of transfer trips on the travel code?
1 Answers
There is no record on the travel code if the stay does not exceed 4 hours. Introduction to Travel Code: The travel code, also known as the Communication Big Data Travel Card, is equivalent to a health code. It is a free query service provided by the China Academy of Information and Communications Technology in collaboration with China Telecom, China Mobile, and China Unicom, the three major telecom operators. It utilizes data received by mobile phones to obtain the user's location based on the cell tower their phone is connected to, offering this service to 1.6 billion mobile phone users nationwide. Users can query all the cities they have visited in the past 14 days through this service. Types of Travel Cards: After obtaining the travel code, the travel card will display colors based on recent travel history, with a total of four types: Green Card, Yellow Card, Orange Card, and Red Card.
