ELECTROMAGNETIC CHIPLESS IDENTIFICATION LABEL COMPATIBLE WITH UNIDIMENSIONAL BAR CODES AND METHOD FOR ENCODING, PRODUCTION AND READING

摘要

The invention relates to an electromagnetic chipless identification label comprising at least one multi-conductive structure printed on a dielectric substrate for identification compatible with unidimensional bar codes. The encoding of said label comprises defining the resonance frequency of multi-conductive structures which will replace bar code digits. The production of said label comprises defining the widths of the conductors of the multi-conductive structure and the separating distances between same in accordance with the corresponding bar code standard (310, 311); and selecting and replacing the corresponding digits in the bar code by printing multi-conductive structures (320a, 320b, 320c). The reading of said label involves the use of a transmission line arranged close to the label, said line moving longitudinally along the label in order to carry out a reading by coupling the electromagnetic field.
