Abstract
A system for location tracking using passive tags includes a reader and a location tracker. The reader receives an identifier associated with a first passive tag. The location tracker receives the location of the passive tag, and maps the location of the first passive tag to the identifier associated with the first passive tag. The location tracker determines the location of an object based on the location of the first passive tag. The location tracker may receive the location of a second passive tag, and map the location of the second passive tag to an identifier associated with the second passive tag. The location tracker may update the location of the object using the location of the second passive tag in response to the reader receiving the identifier associated with the second passive tag.
