Abstract
A system and method are useful for tracking an article at a plurality of stations. A smart tag is associated with each article to be tracked, e.g., by being attached to the article either directly or indirectly, e.g., to a container containing the article. The smart tag includes at least an electronic memory coupled to an antenna by which information from the memory may be transmitted and/or information may be received and stored in the memory. Smart tag control units and antenna at the stations communicate with the smart tags and communicate directly or indirectly with one or more processors that process the information.
