What a digital allergen menu actually does
A digital allergen menu is an interactive online version of your menu where every dish is mapped against food allergens — including the FDA Top 9 and any others you track. Guests access it by scanning a QR code at their table. They select their allergens — peanuts, dairy, wheat, or any combination — and the menu instantly filters to show only dishes that are safe for them.
It's the difference between handing a guest a dense printed allergen chart and giving them a tool that answers their specific question in two taps. AllerIQ builds this entire experience — from allergen mapping to QR code generation — in one platform.
The limitations of printed allergen charts
Most restaurants that take allergen communication seriously today use some version of a printed allergen chart — a table showing which dishes contain which allergens. These are better than nothing, but they have significant limitations:
- ✗They go out of date when your menu changes — and menu changes are constant
- ✗They require guests to manually scan a complex table rather than filtering to their specific allergens
- ✗They are easy to lose, damaged, or out of stock at a table when a guest needs one
- ✗They're expensive to reprint every time a dish or ingredient changes
- ✗They put the cognitive burden on the guest with the allergy, not the technology
Why digital allergen menus solve these problems
Always up to date
Update your menu in AllerIQ's dashboard and the live QR code menu reflects the change immediately.
Filterable by allergen
Guests select their allergens and see only safe dishes — no manual chart reading required.
Accessible from any table
Your QR code is printed everywhere. Any guest with a smartphone can access your allergen menu in seconds.
No reprinting cost
The QR code is permanent. Updates are digital. Zero printing or distribution overhead.
Same source for staff and guests
Your team references the same menu. Consistent information, every time.
Works for every allergen combination
A guest with multiple allergies can filter by all of them simultaneously — something a printed chart can never do.
The guest experience with a digital allergen menu
When a guest with food allergies visits a restaurant using AllerIQ's digital allergen menu:
They see a QR code on the table tent, the printed menu, or at the host stand.
They scan it with their phone's camera. The menu opens in their browser instantly — no app required.
They tap to select their allergens in the filter panel — for example, "peanuts" and "tree nuts".
The menu updates in real time, showing only dishes that don't contain or may contain those allergens.
Dishes with cross-contact risks are flagged with a "may contain" label so the guest can make their own informed decision.
How to create your digital allergen menu with AllerIQ
See the full guide: How to Create an Allergen-Safe Menu for Your Restaurant. In short:
- Import your existing menu via PDF, spreadsheet, or POS export
- Add ingredient data for each dish — AllerIQ auto-maps all common food allergens
- Review and confirm allergen data (typically 10–20 minutes for a full menu)
- Publish — your QR code is generated instantly
- Display the QR code at tables, on menus, and on your website
Important: AllerIQ helps restaurants communicate allergen information clearly, but does not replace proper food safety practices, ingredient verification, staff training, or cross-contact prevention procedures. Restaurants remain responsible for their own food safety standards.

Frequently asked questions
What is a digital allergen menu?
A digital allergen menu is an interactive online menu that displays allergen information for each dish and allows guests to filter the menu by their specific allergens. Guests access it via QR code on their smartphone — no app required.
How is a digital allergen menu different from a website menu?
A regular website menu lists dishes and prices. A digital allergen menu goes further — it shows which allergens each dish contains, flags cross-contact risks, and lets guests filter the entire menu to show only dishes safe for their specific allergens.
How often do I need to update a digital allergen menu?
Update it whenever you change a dish, swap an ingredient, or add a new menu item. With AllerIQ, updates are made in your dashboard and the live menu reflects them immediately — no reprinting and no URL change required.
Can a digital allergen menu help staff as well as guests?
Yes. Staff can reference the same QR code menu as guests. When a guest asks about allergens, staff can direct them to scan the QR code and simultaneously verify the information themselves. It creates a single source of truth for the whole team.
Is a digital allergen menu expensive to maintain?
AllerIQ offers a free plan for restaurants getting started with digital allergen menus. Paid plans unlock additional features like multiple menus and branded templates. There's no reprinting cost since updates are made digitally.
