Abstract
Aspects of tag-based product monitoring and evaluation are described. In one embodiment, an arrangement includes a product package and one or more tags with the product package. At least one of the tags may include a memory that stores a unique identifier, product detail data, and product usage data for the product, a continuity trace that extends across an access covering of the product package, a radio frequency front end configured to be excited by an electromagnetic field, and a tag processor configured to detect a continuity of the continuity trace and identify whether the product package has been opened based on the continuity. When excited in the presence of the electromagnetic field, the tag is configured to transmit a continuity status indicator regarding whether the product package has been opened. In this case, a purchaser may be alerted as to whether the product package has been opened before purchasing.
