Abstract

An RFID system includes a number of RFID tags and an RFID reader. Each RFID tag includes a respective portion of a target data object. The RFID reader is adapted to read each portion of the target data object from the respective RFID tags. A method of providing an identification function includes using an RFID reader to read one portion of a target data object stored on an RFID tag, from among a number of portions of the target data object stored on a respective number of RFID tags.

9. The RFID system of claim 6, wherein the RFID reader is further adapted to read the first portion of the target data object while in a first read mode corresponding to the first coded form, and is further adapted to read the second portion of the target data object while in a second mode corresponding to the second coded form.

10. The RFID system of claim 9, wherein the first and second portions of the target data object are stored in mutually-orthogonal coded form, and the RFID reader is adapted to read the first and second portions of the target data object in respective first and second orthogonal polarization-sensitive interrogator modes.

11. The RFID system of claim 2, wherein the first and second RFID tags are disposed on a common substrate.

12. An RFID system, comprising:

a plurality of RFID tags; and

a plurality of RFID readers;

wherein each RFID tag of the plurality of RFID tags includes a respective portion of a target data object; and
