<p>A method for applying a code (36) onto a substrate (39) is described where the code (36) includes a plurality of code elements obtained by printing inks having specific conductive properties, wherein the digital information associated with the code can be extracted through the use of radio frequency by subjecting the code elements to an alternating or variable electric field. The method includes the steps of: making a polymeric structure (19) including a film (11) and at least one layer (32,34) of polymeric material; printing the code (36) onto the at least one layer (32,34) of polymeric material; applying an adhesive layer (38) onto the at least one layer (32,34) of polymeric material or onto the substrate (39); applying the polymeric structure (19) onto the substrate (39); and transferring the code (36) from the polymeric structure (19) to the substrate (39).</p> |
