The blackening of health codes is mainly caused by the following reasons: first, the health codes applied by users are under review, and after review, green codes, yellow codes or red codes can be displayed; Second, the image has not been refreshed, click the refresh button to try; Third, the user has not been successfully authenticated. Please try again.
Generally, as long as there is no error in filling in the information when applying for the health code, the audit can be completed within 24 hours, so if it is fast, the green code can be restored in about 24 hours; However, if after verification, I am in the middle-high risk area or have other risk contacts, the health code may become a yellow code or a red team. At this point, the green code can only be restored after the corresponding control measures are implemented.
Does the health code black automatically turn green? It depends.
In general, the health code turns black because the information filled in when applying for the health code needs to be reviewed, and the data will automatically turn green after successful authentication. If there is an error in the information, it will show that the approval failed or the verification failed. At this time, it will not turn green automatically, and it needs to turn green again.
However, if the health code turns black due to network failure, the green code can be restored after refreshing the network, and it will not automatically turn green.
3 Can the health code be black? Travel will be restricted.
Health code is a personal QR code based on real data. Different colors of health codes represent different health status of users, and different risk levels have different requirements for access.
Among them, the black health code indicates that the health code does not indicate the risk status, so it is still impossible to judge that the holder is not at risk of contracting COVID-19, and it will be known only after verification. Therefore, for the sake of safety, the health code is generally not released until the health code returns to the green code.
4 Jian code black can be used as nucleic acid? It can be used as nucleic acid.
The blackening of the health code indicates that the status of the health code needs to be verified or refreshed, but this will not affect the user's own nucleic acid detection. Usually, when you do nucleic acid, you just need to explain the situation to the staff.
And the health code turns black, indicating that the health code information status has not been entered or is still under review after entry. Generally, even if the green code is restored after approval, you need to bring your ID card to enter your identity information to make nucleic acid detection results on the health code.
