发明名称 UNIVERSAL RFID TAGS AND MANUFACTURING METHODS
摘要 <p>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 (200, 205, 450) that does not function as a far field RFID tag and is pre-manufactured; and a conductive element (302, 452) 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 (504) of an item (408, 454); and the conductive element is coupled to a second portion (508) 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.</p>
