Take a health code with the camera and print a photo. Is this health code photo valid?

Take the health code with the camera, and then print a photo. This picture of the health code is effective in theory. ..... However, the validity period of this health code was valid at that time ... Because the health code is time-sensitive, after one day, this health code will be invalid.

The function of health code is to display personal travel information in real time to ensure personal health.

Because everyone can't stay in one place for a long time, they always need to move from different places, especially some people need to travel between different cities, so the health code should be updated in real time. It is effective to scan the health code at least once a day.

If for some special reason, you can't carry your mobile phone, or you can't scan the health code with your mobile phone, and then scan the health code with another mobile phone at home and take photos, then the photo of this health code is also valid on the same day ... Only, it is valid for a short time, but when this person leaves the local area, or the next day, this health code will be invalid and need to be scanned again.
