Whether or not vaccination become mandatory, proof of vaccination or a negative test will become the norm for awhile to participate in society, similar to the mask wearing of the past year.

More and more sporting arenas and other public venues are making them a requirement for entrance or service.

Which means more and more counterfeit documents will be in circulation.

I see not reason why QMC and its anti-counterfeiting technology can not focus on both the vaccines themselves and the legal documents they are recorded on.

Remember, verifying the document does not carry any of the concerns of violating any one privacy right.
