1. A method for tracking an interrogator relay unit (IRU):
- emitting an RF interrogation signal using the IRU;
receiving, at the IRU, location data from an RFID tag in response to the RF interrogation signal;
transmitting the location data, an identification information of the IRU, and timestamp data to a remote server using the IRU; and
generating a behavior report using the transmitted location data, the identification information, and the timestamp data.

Abstract
The present invention provides a system and method for tracking an interrogator relay unit disposed on a shopping cart within a store. The method comprises emitting an RF interrogation signal using the IRU; receiving, at the IRU, location data from an RFID tag in response to the RF interrogation signal; transmitting the location data, an identification information of the IRU, and timestamp data to a remote server using the IRU; and generating a behavior report using the transmitted location data, the identification information, and the timestamp data.

14. A method for tracking an interrogator relay unit (IRU) comprising:
-
emitting RF interrogation signals at a prescribed interval using the IRU;
receiving, at the IRU, location data from a plurality of RFID tags in response to the RF interrogation signals;
transmitting the received location data and identification information of the IRU to a remote server using the IRU;
calculating time duration information of the IRU within a transmission range of a first RFID tag using the prescribed interval and a number of times the location data from the first RFID tag is transmitted along with the identification information of the IRU. - View Dependent Claims (15, 16, 17, 18)

19. A system for tracking shopping behavior comprising:
-
a plurality of RFID tags distributed within a structure, each RFID tag configured to contain location information regarding its position within the structure;
an IRU configured to receive the location information from the plurality of RFID tags in response to interrogation signals transmitted by the IRU, wherein the IRU is configured to transmit the location information and an identification information of the IRU to a remote database; and
a report generator configured to query the remote database and to generate a behavior report that comprises a travel pattern of the IRU with respect to the plurality of RFID tags;
wherein the remote database is configured to store and timestamp each location information received. - View Dependent Claims (20, 21, 22, 23)
