Etiqueta electromagnética sin chip para la identificación compatible con códigos de barras unidimensionales y procedimiento de codificación, fabricación y lectura

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.
