Display Your Card on Apple Watch
After you’ve added your vaccination card to both Apple Health and your Wallet on iOS, you finally can fire up the Wallet app on your Apple Watch.
Scroll through the Wallet items until you find your vaccination card. You then can view your vaccination details on your Apple Watch and show them to others as needed.
What About Vaccination Card Photos?
Using Apple Wallet to store your vaccination card only works with a digital version of your COVID vaccination card. It will not work with photos of your vaccine card. Pictures of your vaccination card can be displayed on your Apple Watch using the Photos app. Simply create a new photo album on your iPhone and name it so you can remember it. Then open that album using the Photos app on your Watch.
