System and method to track articles at a point of origin and at a point of destination using RFID
First Claim
1. A system, comprising:
- an article to be tracked;
a flexible radio frequency identification (RFID) device coupled to the article, the RFID device comprising a first thin flexible sheet having a first surface, a dipole antenna disposed on the first sheet, and a single integrated circuit (IC) having stored therein an identification code associated with the article; and
an article tracking system configured to receive the identification code from an interrogation system, wherein the interrogation system includes a first interrogator located at a point of origin of the article and a second interrogator located at a point of destination of the article, and wherein the first and second interrogators are configured to communicate with the RFID device to determine the identification code.

Abstract
A system is provided, which may alternatively be implemented as a method. According to one embodiment, the system comprises an article to be tracked; a flexible radio frequency identification (RFID) device coupled to the article, the RFID device comprising a first thin flexible sheet having a first surface, a dipole antenna disposed on the first sheet, and a single integrated circuit (IC) having stored therein an identification code associated with the article. The system further comprises an article tracking system configured to receive the identification code from an interrogation system, wherein the interrogation system includes a first interrogator located at a point of origin of the article, a second interrogator located at a point of destination of the article, and a third interrogator located on a route between the point of origin and the point of destination, and wherein the first, second, and third interrogators are configured to communicate with the RFID device to determine the identification code.
