US Patent 7036729 Article tracking method and system

A system and method are useful for tracking and/or managing an article at a plurality of stations. An RFID tag including a memory and an antenna is associated with each article to be tracked, or a container, or both. RFID tag readers at the stations communicate with the RFID tags and store information therefrom in a database. The databases may be accessed, e.g., from a remote and/or web-based processor, via communication means whereby the article being tracked or managed may be located and its history obtained.
