Hybrid Radio Frequency Identification (RFID) Tag System
First Claim
1. A hybrid radio frequency identification (RFID) tag, comprising:
- one or more backscattering RFID elements operable to transmit and receive communications to and from a first tag tracking system at a first frequency range, the one or more backscattering RFID elements operable to transmit communications to the first tag tracking system using backscattering of a particular communication received from the first tag tracking system;
one or more active RFID elements operable to transmit and receive communications to and from a second tag tracking system at a second frequency range and operable to transmit communications to the second tag tracking system at the second frequency range with the use of a local power supply; and
a local power supply coupled to the one or more active RFID elements.

Abstract
In certain embodiments, a hybrid radio frequency identification (RFID) tag, includes one or more backscattering RFID elements operable to transmit and receive communications to and from a first tag tracking system at a first frequency range, the one or more backscattering RFID elements operable to transmit communications to the first tag tracking system using backscattering of a particular communication received from the first tag tracking system. The hybrid RFID tag further includes one or more active RFID elements operable to transmit and receive communications to and from a second tag tracking system at a second frequency range and operable to transmit communications to the second tag tracking system at the second frequency range with the use of a local power supply. A local power supply is coupled to the one or more active RFID elements.
