Abstract
A tracking system includes at least one tracking tag, one or more tag trackers, a processor, a first memory, and a second memory. The processor causes the tag trackers to determine a location of the item to be tracked as item location information. The system maintains item location information and a database of associations between the at least one tracking tag and its respective item to be tracked. At least one tag tracker is associated with an item container and is configured to communicate tag information to the tracking system. A method for locating an item tagged with a tracking tag includes querying at least one tag tracker of an item container of a tracking system for a location of the tagged item and displaying the location of the tagged item on a display.
