How to store a digital copy of your vaccination card on your iPhone or Android

If you want to enter certain countries or attend some public events, you’ll need proof that you’ve been vaccinated against COVID-19. If you’ve already received one or more doses, you know how important that little card is. It’s a record of which COVID-19 vaccine you received and the date and place you got it.
While you can get a replacement card if you need one, it’s better to keep your original safe. Lamination is one option, but you can’t update it and will have to get a second card to keep track of additional doses. Thankfully there’s a better solution. Tap or click here to check out our recommendation for protecting your vaccine card.
When you’re out and about, you can keep your vaccine information stored in your phone. Until recently, this involved taking a picture of the card, but now you can keep an official digital version of a COVID vaccination card on a smartphone.
Storing your COVID-19 vaccination card on your iPhone

As of iOS 15.1, you can store your official COVID-19 vaccination card on your iPhone. These are verifiable records that vaccine providers digitally sign. It’s kept in an Apple Wallet and can be presented quickly and easily.
First, you’ll need a QR code. You can get one from your healthcare or vaccine provider. Here’s what to do once you have it:
- Open the camera on your iPhone and hold your phone so the QR code appears in the viewfinder.
- Your phone will recognize the QR code and display a Health app notification.
- Tap the Health app notification.
- Tap Add to Wallet & Health.
- Tap Done.
You may have received a downloadable health record, and you can add this to your iPhone as well:
- Tap the download link on your iPhone.
- Tap Add to Wallet & Health.
- Tap Done.
Once you’ve added your vaccination card to the Wallet app, open it and show the digital card as needed. You can double-click the side button (on an iPhone with Face ID) or double-click the Home button (on other iPhone models) to access the wallet stack and from there select your card.

Car warranty robocalls: Here’s why you get so many
