1. A RFID bead label device configured to be affixed to an unvulcanized rubber article and withstand and maintain RFID operability during vulcanization of the rubber article, the RFID bead label device comprising:
(a) a protective topcoat layer that is an outermost layer of the device;
(b) a rubber adhesion layer configured to attach the device to the unvulcanized and/or vulcanized rubber article;
(c) a polyimide layer with a heat resistant RFID device positioned thereon or therein, the polyimide layer is positioned between the protective topcoat layer and the rubber adhesion layer such that the polyimide layer with heat resistant RFID capabilities maintains RFID operability during vulcanization and post-vulcanization of the rubber article; and
(d) a plurality of polyester layers positioned between the topcoat layer and rubber adhesion layer and that surround the polyimide layer to insulate, protect, and maintain RFID operability of the polyimide layer with heat resistant RFID capabilities during vulcanization of the rubber article.
