> If your doctor uses Epic, the Health app can usually create a SMART credential directly from your medical records instead of downloading a state app.

Slight correction here - the health record is already in the SMART format, e.g. already a signed JWT enveloping a FHIR vaccination record.

The Health App is turning encoding this into a custom URL scheme and tossing that into a QR code.

The reverse also works - I can scan the QR code and import it as a vaccination record into the health app.
