Detecting allergens present in a product

摘要

A method, system and computer program product for detecting allergens present in a product. A tag (e.g., passive RFID tag) receives a query from the user of a computing device containing a list of allergens to determine if an allergen is present in the product (e.g., product for ingestion). Product information associated with the product in stored in secure memory (e.g., write-only memory) on the tag. The tag determines if an allergen to the user is present in the product using the list of allergens in the query as well as the product information associated with the product. The tag then notifies the user of the computing device regarding whether an allergen to the user is present in the product based on the determination. In this manner, allergens are detected in a product and made known to the user.
