1. A Radiofrequency Identification/Magnetic Frequency Identification (RFID/MFID) system, comprising:

  • an RFID/MFID tag that is adapted to provide an RF identification signature when interrogated with an electric travelling wave and to provide an MF identification signature when interrogated with a magnetic travelling wave; and

    an RFID/MFID reader;

    wherein;

    the RFID/MFID tag includes a target data object;

    the RFID/MFID reader is adapted to read electrical and magnetic signatures of the target data object from the RFID/MFID tag;

    the RFID/MFID reader is adapted to direct an electromagnetic travelling wave at the RFID/MFID tag;

    the electromagnetic travelling wave includes an electrical component and a magnetic component;

    the RFID/MFID tag includes an RC circuit and a magnetic field coil;

    the RC circuit and the magnetic field coil are adapted to store energies of the electrical component and the magnetic component, respectively, of the electromagnetic travelling wave;

    the RC circuit and the magnetic field coil are adapted to echo the stored energies of the electrical component and the magnetic component, respectively, when the respective stored energies of the electrical component and the magnetic component reach predetermined thresholds;

    the RFID/MFID reader is adapted to read the echoes of the stored energies of the electrical component and the magnetic component as the respective electrical and magnetic signatures of the target data object; and

    the RFID/MFID reader is adapted to correct for a phase difference of the electrical and magnetic signatures of the target data object.
