Abstract
Methods and apparatuses for tracking an item having an associated radio frequency identification (RFID) tag are described. A change in a physical attribute of the item is detected. Information stored in the tag is updated based on the detected change. Information stored in a database may also be updated based on the detected change. In another aspect, a second tag associated with a person is determined to be located within a predetermined range of a first tag associated with an item. As a result, information is stored in the first tag regarding the person.
