Abstract:
1. A system for tracking a plurality of assets, comprising: a central computer system, said central computer system maintaining a plurality of records relating to said assets; a network, said central computer system being in electronic communication with said network; a plurality of interface devices, each of said interface devices being adapted to communicate with said network; and a plurality of transponders, each of said transponders being associated with a respective one of said assets and storing an identifier identifying the particular asset with which the transponder is associated, each of said transponders being adapted to receive from one of said interface devices at least one RF signal that is generated at the direction of said central computer system and in response thereto to generate and transmit a response signal including the identifier identifying the particular asset with which the transponder is associated; wherein each of said interface devices is adapted to (i) receive the response signal that is transmitted by each of a particular one or more of said transponders, and (ii) generate and transmit to said network at least one second response signal, said at least one second response signal including each identifier that was included in each response signal received by the interface device, wherein the at least one second response signal is transmitted to said central computer system through said network, and wherein said central computer system uses the at least one second response signal received from one or more of said interface devices to update one or more of said records.
