How to protect your COVID vaccination card digitally: Dos and don’ts

How to protect your COVID vaccination card digitally: Dos and don’ts

On April 19, everyone in the United States aged 16 and older becomes eligible for a COVID-19 vaccine appointment. After you get jabbed, you’ll receive a comically old-school 3-inch by 4-inch paper card as proof of your immunization status. You can protect that piece of cardstock by sticking it into an inexpensive badge holder* (Amazon sells a pack of 10 with a resealable zipper for $10), but that doesn’t ward off the possibility of misplacing or outright losing it.

You should have a digital copy as backup. And make it a good one: It should be clear, sharp, and easy to read. You may need it as proof of vaccination or as a way to recall appointment details when trying to replace a lost card. And because your vaccination card displays sensitive personal information that can be used for identity theft, a digital version should also be kept secure.

To achieve that, here’s what you should (and shouldn’t!) do.

*Note: Experts currently don’t recommend laminating your physical card just yet, as you may need to add annotations of future booster shots down the road.

Do: Use a good app

Smartphone photos work perfectly fine for digitizing your vaccination card. To get a good snap, take it in a well-lit area on a flat surface, preferably set against a plain, dark background. (It will make it easier to get a clean crop without cutting off too much of the edges.)

Your phone’s default camera app will work fine for taking the photograph, but to get automatic cropping, lens distortion correction, plus color and exposure correction, download and use a dedicated scanning app. Scanning apps provide the added advantage of saving files as PDFs as well. We like Adobe Scan (Android, iOS; login required) or Evernote Scannable (iOS).

You may, of course also take photos with a camera or a scanner, for greater control over how the file is stored. Free programs like GIMP (Win, MacOS) or Paint.net (Windows) can handle the image corrections necessary for a bright, clear picture.

Do: Back up this digital copy

Like paper cards, digital files can become lost. (Usually through accidental deletion.) Make a backup of your backup to save yourself potential headaches down the road.

Now, most people will simply email themselves a copy of the file to achieve this—but we recommend instead uploading the photos to a cloud service or saving them locally to your computer. Cloud storage from the big services (Google, Apple, Dropbox, Microsoft) use encryption both at rest and in transit, while local storage gives you full control over the data (including the ability to encrypt it). In contrast, email providers don’t universally encrypt email and email attachments.
