Method and System for Tracking RFID Tagged Objects

A method and system for tracking Radio Frequency Identification (RFID) tagged objects is disclosed. The system employs a mapping tool already know in the art to continually scan RFID tagged objects and maintain position of each object in real time in a database. The information can then be used either by a user directly or indirectly to locate an object at any given time.

The method and system employs a combination of an imbedded mapping tool with an RFID reader and stationery RFID reader for scanning RFID tagged objects continuously.

In case of a stationery RFID reader, walls of a room are tagged with RFID tags. The stationery RFID reader reads position of the RFID tags associated with the walls for the room and updates the database with signal strength of the RFID tags. The system then calculates the stationery RFID reader's relative position in the room with respect to the walls. Subsequently, the stationery RFID reader scans for other objects tagged with RFID tags and updates the database with signal strength of each the RFID tags associated with the RFID objects. Consequently, the system finds relative position of each of the RFID objects in the room. Accordingly, the database is updated.

Similarly, jn case of an embedded mapping tool with RFID readers, the embedded mapping tool moves around scans objects tagged with RFID tags. As the embedded mapping tool is already aware of its relative position in a room...
