Abstract

An RFID/MFID system includes a tag and a reader. The tag 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. The tag includes a target data object. The reader is adapted to read electrical and magnetic signatures of the target data object from the tag. A method of providing an identification function includes reading electrical and magnetic signatures of a target data object from tag. The tag provides an RF identification signature when interrogated with an electric travelling wave and provides an MF identification signature when interrogated with a magnetic travelling wave.
