Barcode and ingredient-label scanning
A barcode is convenient, but it should not be the only way to check a product. Allergy Scan supports barcode lookup as well as ingredient-label photos. If product data is missing—or you simply want to review what is printed on the package—you can scan the label itself.
From ingredient text to personal matches
After ingredients are detected, Allergy Scan normalizes supported names and compares them with your selected restrictions using rule-based matching. For example, a milk restriction can be connected with a recognized milk-derived term such as casein. Results focus on the match and its explanation rather than a generic health score.
Why the current package label still matters
No food allergy scanner can see everything. Optical recognition can miss small or unclear text, databases may be outdated, recipes can change, and cross-contact risks may appear elsewhere on the package. Allergy Scan is designed to make label review clearer—not to replace it.
Frequently asked questions
How does a food allergy scanner work?
Allergy Scan reads product information from a barcode or ingredient-label photo, normalizes detected ingredient names, and compares them with the allergies and restrictions in your profile.
Can I scan an ingredient label without a barcode?
Yes. You can photograph an ingredient label when a barcode is unavailable or when you want to check the printed ingredient text directly.
Can a food allergy scanner detect every allergen?
No. Text recognition and product databases can be incomplete, recipes can change, and cross-contact may not appear in an ingredient list. Always verify the current package label.
Does the scanner recognize other names for allergens?
Allergy Scan normalizes supported ingredient relationships, such as connecting casein with milk, before comparing the ingredient list with your profile.
