Travel with food allergies
An Allergy Card for Spain That Speaks Spanish — Offline
Eating out in Spain means tapas bars, marisquerías and busy kitchens where English is hit-or-miss. TrustBite shows the waiter a clear allergen card in Spanish, works with no signal, and lets you scan barcodes and menu photos to catch the hidden traps — shared fryers, seafood everywhere, nuts in sauces and gluten in the smallest tapa.
Why a Spanish allergy card beats a printed one
A single printable card gets lost, crumples, and can't adapt when your plans change. TrustBite carries all 14 EU-regulated allergens in one app and renders your personal card in Spanish — plus 23 other languages if you cross into Portugal, France or fly home. You pick exactly which allergens to flag and at what severity, add an ICE emergency contact right on the card, and hand your phone to staff. It works fully offline, so a rural cortijo with no bars of signal is no problem. When the kitchen has questions, the scanner and menu tools help you answer them on the spot instead of guessing.
Spain's real allergen traps — name them at the table
Shared fryers are the big one: patatas bravas, croquetas, calamares and churros often fry in the same oil, so 'gluten-free' fries can carry gluten or fish traces — ask if the freidora is separate. Seafood hides far beyond the obvious: many arroces and paellas are built on fish or shellfish stock (caldo de pescado), and 'a bit of jamón' dishes sometimes share pans with gambas. Nuts turn up in sauces — romesco and picada are almonds and hazelnuts, turrón is everywhere at Christmas, and marzipan sneaks into pastries. Gluten lurks in tiny tapas: croquetas, tortilla with added flour, morcilla with rice-or-wheat, and bread rubbed with tomato (pan con tomate). Say the dish name, then let the card and scanner confirm.
Scan barcodes and menus before you order
At a supermercado or a gas-station stop, scan a product barcode and TrustBite checks it against the Open Food Facts database, returning a simple green, yellow or red verdict for your profile — handy for jamón packs, sauces and snacks with dense Spanish labels. In a restaurant, photograph the menu or a dish and the AI reads the Spanish text and flags likely allergens so you know what to ask about. Free covers the card and a few daily scans; optional Pro unlocks unlimited scans and the AI photo and menu analysis. None of it replaces asking the kitchen — it makes the conversation faster and more precise.
FAQ
Does the allergy card work without internet in Spain?
Yes. Your allergen card renders fully offline, so you can show it in a mountain village, on a ferry to the Balearics, or anywhere with no signal. Barcode and AI menu scanning need a connection, but the card itself never does.
Is the card actually written in Spanish?
Yes. Spanish is one of TrustBite's 24 card languages, so staff read your allergens in their own language. You can also switch to English, Catalan-region travelers can rely on Spanish being understood, or pick any of the other 22 languages as you travel.
How does it handle shared fryers and seafood stock?
The card states your allergens clearly so you can ask the specific question — is the fryer separate, is there fish stock in the rice. TrustBite flags what to watch, but a shared freidora or a caldo de pescado is something only the kitchen can confirm, so always verify with staff.
Is TrustBite free, and is it a medical device?
The core card and a limited number of daily scans are free; optional Pro adds unlimited scanning and AI photo and menu analysis. TrustBite is an aid to communication, not a medical device, and does not diagnose or guarantee safety.
TrustBite is a communication aid, not a medical device. It does not diagnose allergies or guarantee any dish is safe. Always verify ingredients and preparation directly with restaurant staff, and read product labels yourself. Automated barcode and AI results can be incomplete or wrong. If you experience a severe allergic reaction, use your prescribed emergency medication and call the emergency services immediately — in Spain and across the EU, dial 112.
