UNIVERSAL RFID TAGS AND MANUFACTURING METHODS
First Claim
1. A radio frequency identification (RFID) device comprising:
- a near field only RFID tag that does not function as a far field RFID tag and is pre-manufactured;
a conductive element independent from the near field only RFID tag and adapted to function as a far field antenna; and
wherein the near field only RFID tag is coupled to a first portion of an item; and
wherein the conductive element is coupled to a second portion of the item, the first portion and the second portion located such that the near field only RFID tag is coupled in proximity to the conductive element such that the RFID device functions in both a near field and a far field.

Abstract
Radio frequency identification (RFID) devices, and methods of manufacture are described herein. In one implementation, a RFID device comprises: a near field only RFID tag that does not function as a far field RFID tag and is pre-manufactured; and a conductive element independent from the near field only RFID tag and adapted to function as a far field antenna. The near field only RFID tag is coupled to a first portion of an item; and the conductive element is coupled to a second portion of the item, the first portion and the second portion located such that the near field only RFID tag is coupled in proximity to the conductive element such that the RFID device functions in both a near field and a far field.

20. A radio frequency identification (RFID) device comprising:
-
a near field only RFID tag, wherein the near field only RFID tag does not function as a far field RFID tag; a conductive element independent from the near field only RFID tag and adapted to function as a far field antenna; and a coupling structure adapted to locate the conductive element in a proximity relationship with the near field only RFID tag to couple the conductive element to the near field only RFID tag such that the RFID device functions in both a near field and a far field; and wherein the coupling structure is adapted to allow the proximity relationship of the conductive element and the near field only RFID tag to be later removed to decouple the conductive element from the near field only RFID tag such that the RFID device no longer functions in the far field.

21. A method of making a radio frequency identification (RFID) device comprising:
-
coupling a near field only RFID tag to a first portion of an item, wherein the near field only RFID tag does not function as a far field RFID tag and is pre-manufactured; coupling a conductive element to a second portion of the item, wherein the conductive element is adapted to function as a far field antenna; and wherein the coupling steps result in that the near field only RFID tag is located proximate to and coupled in proximity to the conductive element such that the RFID device functions in both a near field and a far field.
