California launches a digital vaccine verification system built using the open-source SMART Health Card Framework, with QR codes to show COVID-19 vaccine status

Vaccinated Californians now have a new way to show they are inoculated against the coronavirus without carrying around a flimsy paper card. Source: State of California and State of California .

Mercury News

Context & Ripple Effects

Los Angeles County had already partnered with Healthvana to put vaccination status into services such as Apple Wallet through a county-level digital vaccination credential. California’s statewide move shifts that convenience from a local partnership toward a common QR-based verification format.

The system became more consequential as California later published its Digital Vaccine Record front-end and middle-tier code, giving other states a deployable implementation of the same framework.

First-order effects

  • Vaccinated Californians gain a scannable alternative to carrying a paper vaccination card, while organizations checking COVID-19 status can use a QR-based credential.
  • California becomes the operator of a statewide digital record experience built on the SMART Health Card framework rather than a county-specific wallet integration.

Second-order effects

  • California’s later code release lowers the implementation barrier for other states that want compatible SMART Health Card deployments, reinforcing the framework around the state’s initial rollout.
  • A common QR format makes verification less dependent on the particular app or wallet used to display the record, favoring providers and verifiers that support SMART Health Cards.

Third-order effects

  • As SMART Health Cards reached broader availability in the US, California’s implementation pointed to public credentials being distributed through interoperable verification standards rather than isolated local programs.
  • California’s later plan to support state IDs in Apple Wallet and Google Wallet suggests a broader state shift toward digitally presented government-issued credentials, though vaccine records and mobile IDs remain separate programs.

The trend: Government credential programs are moving from paper and local integrations toward QR-based, interoperable digital records that can be displayed across wallets and verification tools.

    1/ Today, California became the first state in the country to launch an open source, standards-based digital vaccination record. Using the SMART Health Card framework, any resident who wants a digital copy of their vaccination record can get one at https://myvaccinerecord.cdph.ca…

    CDPH + CDT announced My Vaccine Record at https://myvaccinerecord.cdph.ca.gov/. The tool is an easy way for residents of #CA who received a #COVID19 vaccine to access their digital record from the state's immunization registry systems. https://twitter.com/...

    @rklau Worked pretty slick. The QR code is ginormous preventing its use on Apple wallet. Any chance of shrinking the QR code payload?

    @CAPublicHealth @CADeptTech @R_Thaler @GavinNewsom @calonghurst @Walmart @Clear 12/ At #WWDC21, Apple recently announced users' upcoming ability in iOS 15 to download verifiable vaccination or test result records from an online browser or QR code, using the SMART Health Cards fra…

    This is fantastic. Cheers to @rklau and his whole team. https://twitter.com/...

    @citylifejc Apple has announced support for SMART Health Cards already; when it ships, this will work out of the box. As other platforms develop similar capabilities, benefit of us going w/the open standard is that it will also just work :)
  • @rklau Rick Klau on x
    @rstephens we're following the SMART Health Card spec, which iOS 15 will support natively

    This is what (digital) leadership looks like! more and more of the information we need to improve our quality of life rests in state and local databases; witness the spirit of states as “laboratories of democracy”! https://twitter.com/...
  • @mpflowersnyc Mike Flowers on x
    This is fantastic. Transparent, open source access to vaccination data by those who own it, at their election. https://twitter.com/...
  • @boltyboy Matthew Holt on x
    California is out today with a vaccine passport — and it works! https://twitter.com/...
  • @rschooley Schooley on x
    Florida: we will never have vaccine passports! California: here you go. https://twitter.com/...
  • @dlthings @dlthings on x
    Super easy, fellow Californians. Follow the prompts, take a screenshot of the QR code, boom you got your digital not-a-vaccine-passport. https://twitter.com/...
  • @mikeolson @mikeolson on x
    This is awesome. California Department of Public Health maintains a registry of everyone who was administered a COVID vaccine in the state. You can set up PIN-protected access to a QR code reporting your status. Secure and reliable in a way that those paper cards aren't. Nice! ht…

    Every state should do this https://twitter.com/...

    I look forward to putting away my physical vaccine card in the safest, very back part of my hall closet like the ark of the covenant... https://twitter.com/...

    Just tried this and it worked. Super helpful. https://twitter.com/...
