What is a SMART Health Card?
A SMART Health Card (SHC) is a W3C-style verifiable credential for health information — a signed FHIR bundle, compressed, encoded as a numeric shc:/ URI, and rendered as a QR code. It was developed by the Vaccine Credential Initiative (VCI), a coalition of Microsoft, Salesforce, Oracle, the Mayo Clinic, the Commons Project, MITRE, and Epic, and adopted by the CDC, California, New York, Quebec, the EU (as part of the Digital COVID Certificate interoperability), and 30+ other health authorities.
The QR is tamper-evident: the JWS signature binds the health data to the issuer's public key, which a verifier retrieves from the issuer's /.well-known/jwks.json. Scan with the SMART Health Card Verifier app (Apple / Android) or any compatible health wallet and you see a green check, the issuer name, and the decoded credential.
Why the numeric encoding?
Each character of the JWS is encoded as two base-10 digits — the character's Unicode ordinal minus 45. This lets the QR use the efficient Numeric encoding mode, which packs about 20% more data than Binary mode. A typical vaccination record fits in a V22 QR (~1,191 digits). Longer bundles get chunked: shc:/1/3/..., shc:/2/3/..., shc:/3/3/.... In practice, production SHCs rarely need chunking — issuers trim bundles to single-chunk size.
What's encoded inside?
The JWS (after chunk-reassembly and base-10 decoding) is a compact-serialised JSON Web Signature. The payload is a DEFLATE-compressed JSON FHIR bundle with one or more Immunization, Observation, or Patient resources. The JWS header carries a key ID (kid) that the verifier uses to fetch the issuer's ES256 public key.
What this generator is not
We do not issue SMART Health Cards. An SHC's value is its cryptographic signature from a trusted health authority (CDC, state health department, hospital, pharmacy). A self-signed card verifies as untrusted by every SHC verifier app. To get a signed shc:/ URI, log in to your provider's patient portal (Epic MyChart, Cerner HealtheLife, CVS, Walgreens, state immunisation registry) and export it from the Health Card download UI. Paste the URI here; we wrap it as a QR for printing, sharing, or saving.
Where SMART Health Cards are accepted
- Travel — CommonPass, VeriFLY, and airline apps scan SHCs for international entry checks (historical COVID-19 vaccination proof; still active for yellow-fever and other travel-mandated vaccines in select countries).
- Employment — healthcare employers, universities, and federal-contractor workflows use SHC verifiers for onboarding compliance.
- Events — concert venues, conferences, and cruise ships have historically accepted SHCs in lieu of paper records.
- Pharmacy / clinic check-in — Epic, Cerner, and modern EHRs scan SHCs to auto-populate immunisation history.

Frequently Asked Questions
Where do I get a SMART Health Card to encode?
From your healthcare provider's patient portal. Epic-based MyChart (most US health systems), Cerner HealtheLife, CVS, Walgreens, Walmart Health, and state / provincial immunisation registries (California Digital Vaccine Record, New York Excelsior Pass, Quebec VaxiCode) all offer SHC download. Look for a 'Share COVID-19 Vaccination Record', 'SMART Health Card', or 'Immunisation Record QR' option.
Can I create my own SMART Health Card?
Technically yes — anyone can generate a self-signed shc:/ URI — but no verifier app will trust it. SHC value comes entirely from the issuer's signature being in the VCI Directory or the CommonTrust Network. Self-signed cards show as untrusted red warnings.
What's the difference between a SMART Health Card and the EU Digital COVID Certificate?
Different payload and signing standards. SHC uses W3C Verifiable Credentials on FHIR with ES256-signed JWS. The EU DCC uses CBOR Web Tokens with COSE signatures. Interoperability bridges exist (the CommonTrust Network accepts both) but the QR payloads are not interchangeable.
Why is the QR so dense?
SHC packs a compressed FHIR bundle plus a cryptographic signature into a single QR. Even with Numeric-mode encoding and deflate compression, a full vaccination history can approach the V22 QR limit (~1,191 digits = ~550 FHIR bytes). Use a high-quality print with ECC level L or M and at least a 2-module quiet zone.
What about the multi-chunk shc:/1/2/... format?
Production SHCs rarely use chunking — the VCI recommends trimming bundles to fit a single QR. If you do need to chunk, paste each chunk in order and generate one QR per chunk. Verifier apps scan them sequentially and reassemble before JWS verification. Chunk one: shc:/1/2/[digits], Chunk two: shc:/2/2/[digits].
Does the QR contain my medical record?
It contains whatever FHIR resources the issuer included — typically the minimum for the credential's purpose: name, date of birth, vaccine manufacturer / lot / date for immunisation records; test type / result / specimen date for lab results. A full EHR is not encoded. Treat the QR as sensitive: name + DOB + provider-visible health fact is PHI under HIPAA.
Can I revoke or update a SMART Health Card?
Not directly — the QR is a signed snapshot. If the underlying record changes (correction, new dose, revocation), your provider issues a new shc:/ URI. Verifier apps check the issuer's revocation list (if published) via the key ID. Old QRs keep decoding but may show as revoked.
Is this format used outside vaccination records?
Yes. SHC is a general-purpose W3C Verifiable Credential on FHIR — valid for any FHIR resource. Active deployments include lab results (PCR / antigen), immunisation histories (childhood + travel), prescriptions (pilot programs), discharge summaries (some Epic deployments), and insurance membership cards (early trials).
Which apps verify SMART Health Card QRs?
SMART Health Card Verifier (Apple App Store / Google Play), CommonPass, VeriFLY, CLEAR Health Pass, Apple Health (built-in since iOS 15.1), Google Wallet (since 2022), and Epic MyChart. Built-in iPhone camera recognises shc:/ URIs and hands off to Apple Health automatically.
