Re: [113attendees] If one tests positive in Vienna

Not really useful to the actual issue about availability in the u.s., 
but maybe two interesting references as context:

The basis for the Electronic Health Certificate (HCERT) used in the EU 
had to be done relatively well, relatively fast - so that was done on 
github:

Essentially, it's a CWT, compressed with deflate, encoded in base45, and 
represented as a QR code.

Canada (or only Quebec?), I believe this is using this as a basis:

Similar story: based on JWT using compact JWS serialization, the JWS 
payload is stripped of whitesaces, compressed with deflate, and then 
encoded as Numerical Mode QR code.

So... JOSE and COSE ftw, I guess :-)

There are probably way more details out there that I am missing, but I 
do not attend to clutter the attendee list with that.

Viele Grüße,

Henk

These are on white heavy paper, typically filled in by hand in pen (so, not even “printout with your name”), and have never met a QR code. There are any number of different private and state efforts to provide some kind of more official-looking and machine-readable thing, but no national standard beyond the CDC piece-of-paper.
