What a barcode can tell you
A barcode can point to a database record. That record may be missing, outdated, regional, or connected to a different formulation.
Barcode or ingredient label?
For allergy checks, the ingredient list matters more than the barcode
A barcode identifies a product, but it does not display the current ingredients on the package. Food Checker works from a label photo, food photo, or product name.
What to know
A clearer way to use this check
Use the method that fits the information available, then verify the exact food before making a decision.
What the label shows
The package in your hand contains the manufacturer’s current ingredient list and allergen declaration for that item.
The Food Checker approach
Capture the complete ingredient panel whenever possible. Use a food photo or name only when printed ingredients are unavailable, and always verify before eating.
Choose the best input
Label, photo, or name?
Use a complete ingredient label whenever it is available. Photos and product-name checks are helpful starting points when packaging is missing.
