I don't think QMC's plan is to QD tag people! Only

I don't think QMC's plan is to QD tag people! Only a QR code would be needed when establishing a person's identity. They would QD tag the test for scanning it into QDX HealthID to provide anticounterfeiting security. Every test must be securely logged into QDX HealthID but that would not show on the Testee's screen.

Is there anywhere on the examples you provide that the tests themselves cannot be fakes? How about the type of test, the accuracy of the test, the turnaround time and the availability of the test?

Finally, QMC CTO Jay Williams discusses the ethics, importance and implications of test data privacy in the Atlantic Council Webinar posted on QMC homepage. All the examples you provide, such as Evident and Red Stripe make the point that they and the employer have full access to all the data and health status. It looks like the Testee gives up their rights when they agree to take the test. QDX HealthID is the only one that makes the point that the Testee owns his test results and decides. who to share it with, not the testing company.
