1. A method for identifying items carried by a mobile structure, comprising:
- (a) at a first location of the mobile structure, directing a first read signal to a load carried by a mobile structure to identify an initial set of radio frequency identification (RFID) tags;
(b) at a subsequent location of the mobile structure, directing a subsequent read signal to the load carried by the mobile structure to identify a subsequent set of RFID tags; and
(c) comparing the initial set of RFID tags and the subsequent set of RFID tags to determine a set of RFID tags associated with the load.

Abstract
Methods, systems, and apparatuses for identifying items carried by a mobile structure are described. At a first location of the mobile structure, a first radio frequency identification (RFID) read signal is directed to a load carried by the mobile structure to identify an initial set of RFID tags. At a subsequent location of the mobile structure, a subsequent read signal is directed to the load carried by the mobile structure to identify a subsequent set of RFID tags. The initial set of RFID tags and the subsequent set of RFID tags are compared to determine a set of RFID tags associated with the load.

20. A radio frequency identification (RFID) reader system, comprising:
-
an antenna;
a transceiver coupled to the antenna; and
a baseband processor coupled to the transceiver;
wherein the baseband processor comprises a compare module configured to compare a initial set of tags to a subsequent set of tags to determine a set of tags associated with a load carried by a mobile structure;
wherein the initial set of tags are tags read by the reader at an initial location for the mobile structure, and the second set of tags are tags read by the reader at a subsequent location for the mobile structure. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27)
