Abstract
A method and system for location determination and guidance using radio frequency identification (RFID) are disclosed. A location of a mobile RFID reader can be determined by detecting stationary RFID tags located at fixed locations. Each RFID tag stores location information associated with its position as well as location information of at least one other RFID tag. The location information stored by each RFID tag can be used to direct a user from one RFID tag to another. Thus, RFID technology is also used to guide mobile RFID reader between the fixed locations of the stationary RFID tags.
