System and method for validating radio frequency identification tags
First Claim
1. A system for validating each of a plurality of radio frequency identification tags disposed on a web in close proximity to one another to ensure proper functioning thereof, said system comprising:
- a narrow angle radio frequency identification tag reading station which reads a designation of each radio frequency identification tag individually in order to generate a first list of tag designations read thereby;
a wide angle radio frequency identification tag reading station which reads designations of a plurality of radio frequency identification tags simultaneously from a long range in order to generate a second list of tag designations read thereby; and
a processor which compares the first list of tag designations with the second list of tag designations and evaluates the functionality of the plurality of radio frequency identification tags based at least in part upon the comparison.

Abstract
A system for validating each of a plurality of radio frequency identification tags disposed on a web in close proximity to one another to ensure proper functioning thereof includes a narrow angle radio frequency identification tag reading station which reads a designation of each radio frequency identification tag individually in order to generate a first list of tag designations read thereby and a wide angle radio frequency identification tag reading station which reads designations of a plurality of radio frequency identification tags simultaneously from a long range in order to generate a second list of tag designations read thereby. The system also includes a processor which compares the first list of tag designations with the second list of tag designations and evaluates the functionality of the plurality of radio frequency identification tags based at least in part upon the comparison.

25. A system for validating each of a plurality of radio frequency identification tags disposed on a web in close proximity to one another to ensure proper functioning thereof, said system comprising:
-
a narrow angle radio frequency identification tag reading station which reads a designation of each radio frequency identification tag individually in order to generate a first list of tag designations read thereby, said radio frequency identification tag reading station comprising;
a shielding structure of conductive material which is built as a waveguide to structure and contain illumination of radio frequency energy so only a single tag is energized and actuated at a time;
a transmitting antenna disposed parallel to a dipole antenna of the radio frequency identification tags for introducing radio frequency energy into the waveguide;
a receiving antenna which receives signals transmitted by the transmitting antenna; and
electrically conductive tunnels provided at an entrance and an exit for the web of radio frequency identification tags, which tunnels act to suppress and absorb any radio frequency energy that leaks into or is reflected into the tunnels;
a wide angle radio frequency identification tag reading station which reads designations of a plurality of radio frequency identification tags simultaneously from a long range in order to generate a second list of tag designations read thereby; and
a processor which compares the first list of tag designations with the second list of tag designations and evaluates the functionality of the plurality of radio frequency identification tags based at least in part upon the comparison. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
