ABSTRACT:
A document or object includes resonant tags, such as thin dipoles, and a machine-readable symbol, such as an area symbol, secured thereto. A reader reads the symbol and determines response characteristics encoded therein for the dipoles. The reader then can interrogate the dipoles and, together with the response characteristics and determined orientation (derived from the symbol), accurately determine resonant response characteristics received from the dipoles. Alternatively, a printer may interrogate the document to determine the response characteristics of the dipoles in the document, and then print the corresponding symbol.
