How AllergyPass Works,
From Card to Kitchen

From picking your allergens to what actually lands in your inbox after you buy: here's the full path your card takes, and what to carry once you're at the table.

Quick answer: you select your destination and allergens in the Card Builder, choose a tier, and check out if you're buying a paid destination. What arrives afterward is a high-resolution card image, a wallet pass link, a print-ready PDF with a wallet-sized cutout card, and a short list of recommendations for the destination you're traveling to.

Step 1: pick your destination and your allergens

Everything starts in the Card Builder. You choose the destination language first, then add your allergens or dietary restrictions one at a time and set a severity level for each. The card preview updates as you go, so you can check the wording and the layout before you commit to anything. There's no limit on how many allergens you add, and nothing is saved to an account until you're ready.

Step 2: choose a tier

The Free Starter tier covers English at no cost, with unlimited allergens. A Single Trip Pass unlocks one paid destination for a flat $4.99. All Access covers every live language for travelers visiting more than one country. Whichever tier fits, the checkout happens right in the builder, so you see exactly what you're buying before you pay.

What arrives in your email after you buy

Once your order goes through, one email carries everything you need for that destination.

The card, as a real image. A high-resolution copy of your finished card, ready to save to your phone's camera roll or attach to a message.

A wallet link. One tap adds the card to Apple or Google Wallet. Wallet passes cap out at three allergens by the format's own design, not a choice AllergyPass makes, so if your list is longer than that, lean on the image or the PDF for the full picture.

A printable PDF with a wallet-sized cutout. The first page is a full-sheet version for printing at home or a print shop. The second page is trimmed to wallet size with cutting guides, so you can cut it out and laminate it for a backup copy that never needs a charge or a signal.

Recommendations for where you're going. A short, destination-matched list, things like travel insurance, an eSIM, or ground transport for that specific country, not a generic list repeated on every email.

Why the wallet cap is three Apple and Google both fix how much a wallet pass can display, and three allergens is what fits cleanly on the card face without shrinking the text past readable. It's a constraint of the wallet format itself. Your card image and your printable PDF carry your complete list regardless of how many allergens you have.

What to actually carry once you land

Most travelers end up carrying two things at once: the wallet pass or saved image as the everyday option, since it's already on the phone, and the laminated wallet-sized cutout as the backup that keeps working if the phone dies or loses signal. The email itself is worth keeping too. It doesn't expire, so it's a second copy you can pull up from any device if you lose the others.

Frequently asked questions

How many allergens can I add to my wallet pass?

Apple and Google Wallet passes hold up to three allergens. That's a limit of the wallet card format itself, not a limit AllergyPass sets. If you have more than three, the card image and the printable PDF carry your full list with no cap.

Do I need an account or a smartphone to use the card?

No account is required for the free tier or any paid tier. Your card works as a saved image, a wallet pass, or a printed card, and the image and printed card both work with no signal and no phone at all.

What if I change my allergens after I've already bought my card?

Your Single Trip Pass or All Access plan lets you rebuild your card any time for the destinations you own, so you can update your allergen list and download a fresh image, PDF, or wallet pass instead of buying again.

What are the destination recommendations in my email?

A short list matched to the destination on your card, things like travel insurance, an eSIM, or ground transport, not a generic ad block. If none of it's relevant to your trip, it's easy to ignore.
