Do the green travel codes with asterisks in Beijing need to be isolated?

1. Travel cards marked with an asterisk may not be quarantined. It depends on the specific situation. If the user goes to a medium-high risk area, he will be quarantined. If the user has never been to a medium-high risk area, he does not need to be quarantined.

2. The travel card is marked with an asterisk "*", which indicates that the user has cities with medium and high risk areas in the past 14 days of travel, but it does not mean that the user has actually been to these medium and high risk areas. When the epidemic prevention manager sees the asterisk on the user's travel card, it is suggested to further verify whether the other party has really been to the middle and high risk areas, and then judge whether it is necessary to isolate according to the local epidemic prevention policy. It is not recommended to directly isolate travel card users with asterisks.

3. The travel card analyzes the mobile phone signaling and bill data, which are obtained by the operator through the location of the base station where the mobile phone number used by the user is located. Due to technical reasons such as possible cross coverage of base station signals, limited accuracy of signaling data, delay in data update, etc., there may be some deviation in travel card service data. If the result deviates seriously, please contact the operator's customer service for inspection (Telecom 10000/ Mobile 10086/ Unicom 100 10).
