Abstract
Methods, systems, and apparatuses for radio frequency identification (RFID) items/objects are described. In embodiments of the present invention, resonant frequency characteristics of materials of the items/objects are used to enable RFID functionality in the items/objects. In an aspect of the present invention, a RFID item comprises a resonant material. An integrated circuit (IC) die is electrically coupled to the resonant material. The resonant material functions as an antenna for the IC die. The IC die may be attached to a quadraposer substrate to be electrically coupled to the resonant material.
