Are you planning on bringing a SMART Health card consumers/verifier that would be interested in testing a QR code or .smart-health-card? Alternatively, are you an issuer? Let's use this thread to connect!

Thanks Isaac!
Kevin Durand and I are here with an issuer implementation from Epic. We'll be available and would love to test against other holders & verifiers while we're here.

Hi All, I missed Friday nights intro and I am listening to the recording as I type this. Where are we hanging out today?

Hi Richard, welcome! We're hanging out on this stream today and the Zoom meeting is available for breakouts if anyone needs it.

I have a question on the qrcode. In the sample, it seems to use numeric encoding like shc://23123798273. My api currently produces a qr code of the crednetial itself. Is the numeric encoding required?

This section of the spec details the creation of the QR code, in which the JSON Web Signature (JWS) value is indeed numerically-encoded before creating the QR image.

Thanks Christian, Do you have a reference library in node js that produces the correct output? The library I am using complains that the jws cannot be encoded with numeric... it insists on byte.

qrcode supports manual mode that allows specifying a different encoding for each segment

The "QR Code Generation" of this Jupyter notebook illustrates a basic example using that library (adapted from the source code for generating the examples in the spec, which is another good resource to look at)

Reece, that's the library I am using. I guess I need to convert the JWS to numeric before I put it in there as the library will only accept numeric characters in the segment when you specify "numeric" mode. My question is has anyone implemented the conversion of JWS to numeric encoding via the spec. To be clear:

 var segs = [
                    { data: 'shc:/', mode: 'Byte' },
                    { data: JSON.parse(verifiableCredential).verifiableCredential[0], mode: 'numeric' }
                ]
''
throws an error

I think it see it in the Jupyter notebook
toNumericQr
and splitJwsIntoChunks

Yes you'll need to do the numeric encoding conversion, which you can find in the Jupyter notebook or the spec source code.

Here's a link to the JWS chunking in the example generation code

The MITRE team will be looking to test our reference implementation this week. We've hosted https://connectathon.vci.org (GitHub source: https://github.com/dvci/health_cards) that:

  • can act as an issuer app that can generate QR codes and allows file downloads
  • allows QR codes and file downloads to be scanned or uploaded and verified

We're looking to test verifiers with health cards we generate, and test issuers with our verifier tools (file upload and QR code scan).

We also have some tests in development on inferno-dev.healthit.gov (GitHub source: https://github.com/inferno-community/inferno-core) for issuers that we'd love to try.

Also please check out the ConMan page, where the Cerner team has added details on their health-cards-issue endpoints (secure and unsecured) for testing. Go to http://conman.clinfhir.com/connectathon.html?event=con27 -> Track details and testing -> SMART Health Cards for Vaccination and Testing -> Servers tab.

Re-posting validation tools' links for those implementing support for SMART Health Cards (SHC). The validation SDK is a tool to validate SHC artifacts. Can be run locally, or in docker. The new developer portals expose this capability on a friendly web interface:

  • The developer portal allows you to generate SHC from scratch, or by copy-pasting your data.
  • The verifier portal allows you, you've guessed it, to validate them, getting feedback on their adherence to the spec.

Cerner implementations for the Issuer FHIR API are:

Implementation notes and details on how you can integrate with our implementation can be found here.
We are looking to connect with holder applications that can test against our APIs.

Hey @Michael O'Hanlon , I uploaded a few .smart-health-card files into connectathon.vci.org, that appeared to work successfully. Do the inferno-dev tests only test the FHIR API or do they also support QR codes and files?

@Isaac Vetter The inferno tests (https://inferno-dev.healthit.gov/) were just updated to support $health-cards-issue in addition to the file download
