Tracking a tagged object may include receiving, using a first processor, a first video of an object tagged with a radio frequency identification (RFID) tag and first metadata read from the RFID tag. The first metadata may be stored in association with the first video using the first processor. First updated metadata may be written to the RFID tag using the first processor. The first updated metadata may specify at least one of a time the first video is received or a location of the first processor.

Object tracking using enhanced video surveillance through a distributed network

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.
