The CT WiZ COVID-19 vaccination record is a SMART Health Card. Businesses with a compatible verifier app that follow SMART Health Card standards will be able to scan the CT WiZ QR code, if you choose to share it. The VAMS vaccination certificate has a QR code, but it is not currently compatible with a SMART Health Card verifier app.
The CT WiZ COVID-19 vaccination record is a consolidated record, as VAMS records from Connecticut are reported to the CT WiZ.
