Abstract
Embodiments are discussed herein related to radio frequency identification (“RFID”) and, more particularly, to systems, methods, apparatuses, computer readable media products and other means for integrating two transponders into a tag, where each transponder functions independent from and does not couple with the other transponder. In some embodiments, one of the transponders can be a near field RFID transponder and the other a far field transponder. The near field RFID transponder can be used to, among other things, authenticate the far field RFID transponder. In some embodiments, the far field RFID transponder can be encoded to transmit generic information, while the near field RFID transmits more detailed or user-specific information. Additionally, in some embodiments, the near field and far field RFID transponders can operate in accordance with the same wireless protocol and include their own circuitry and antenna.
