What does the bar code on the health certificate do?

The bar code on the health certificate is for the convenience of managing and recording the personal information and health status of the holder. By scanning the bar code, the name, ID number and health information of the holder can be obtained quickly and effectively. Doing so will help prevent the spread of diseases and ensure public health and safety.

Specifically, the new health certificate is printed with a QR code. As long as you scan the QR code, you can know the name, ID number and health information of the holder. This enables the management and supervision institutions to obtain the health information of the holders more conveniently and quickly, and improves the work efficiency and information accuracy.

In addition, some medical examination centers also provide the function of scanning bar codes to query medical examination reports. This can ensure that only you can view your physical examination report, which effectively protects your privacy.

Generally speaking, the bar code on the health certificate is to make the management and use of the health certificate more efficient, safe and convenient.
