The allergy travel card you can show any waiter, in their language
Eating out in a country where you don't speak the language is the scariest part of traveling with a food allergy. TrustBite turns your allergies into a clear card restaurant staff actually understand — in 24 languages, and it works even with no signal.
A card that works offline, when you need it most
Roaming drops, restaurant Wi-Fi fails, and rural areas have no signal at all — exactly when you're handing your phone to a waiter. TrustBite stores your allergy card on the device, so it opens instantly with zero bars. Build your profile once at home, then show a clean, staff-facing card anywhere: a mountain village in Thailand, a family trattoria in Italy, a night market in Japan. No account login, no loading spinner, no panic.
24 languages, including the ones other cards skip
Most allergy translation cards stop at a handful of European languages. TrustBite speaks 24 — German, English, Italian, French, Spanish, Polish, Dutch, Portuguese, Turkish, Greek and more, plus the hard ones travelers actually struggle with: Thai, Japanese, Chinese and Arabic. Each card names your allergens in proper local script and phrasing, so a kitchen in Bangkok or Cairo reads it the way a local would — not a garbled machine translation.
Scan the barcode, photograph the menu, let AI check
In a supermarket abroad, scan a product's barcode and TrustBite checks it against Open Food Facts, then shows a simple traffic light — green, yellow or red — for your exact profile. At a restaurant, photograph the menu or a dish and the AI flags likely allergens dish by dish. It covers all 14 EU-regulated allergens with severity levels, and you can add an emergency (ICE) contact right on the card in case a reaction turns serious.
FAQ
Does the allergy card really work without internet?
Yes. Once you've set up your profile, the translation card is stored on your phone and opens offline — no signal, roaming or login needed. That's the whole point: it works in the rural, low-signal places where you need it most. The barcode scanner and AI menu analysis do need a connection, but the card itself never does.
Which languages and allergens does it cover?
The card is available in 24 languages, including Thai, Japanese, Chinese and Arabic, and covers all 14 EU-regulated allergens — gluten, peanut, tree nut, milk, egg, fish, shellfish, soy, sesame, mustard, celery, sulphites, lupin and mollusc — with severity levels so staff understand how serious each one is for you.
Is TrustBite free?
Yes, it's free to download and use. Your offline allergy card, the language translations and daily scans are all included. An optional Pro upgrade unlocks unlimited barcode scans and the AI photo and menu analysis, but you never need to pay to show staff your card.
Can I trust it to keep me safe?
Treat it as a helpful aid, not a guarantee. TrustBite is not a medical device and can't replace talking to staff or reading labels yourself. Always confirm ingredients directly with the kitchen, and if you have a severe reaction, call your local emergency services immediately.
