Is there an electronic health certificate that can be printed on paper to modify information?

No, it is illegal to change information at will.

Yes, just add a little money.

You can modify the font or content.

If the physical examination report in paper version is changed to electronic version, the format generated in the future will be PDF version, but even so, it can be modified.

However, the medical report is authoritative. If it is changed without authorization, the individual needs to pay the corresponding legal responsibility. Moreover, at the end of the medical examination report, there will generally be the signature and corresponding seal of the hospital. These places cannot be changed.
