Abstract: Process for making a fabric label (10) containing one piece of unique information; characterized by comprising the following steps: providing a fabric piece (7) comprising a first woven pattern (2) made by a predetermined arrangement combination of weft threads with respect to the warp threads; applying at least one second decorating pattern (4) on said fabric piece (7) to make at least one decoration for a label (10) to be made; associating at least one piece of variable information (5) adapted to uniquely identify a label (10) to be made; detecting a reference image (12) for every second decorating pattern (4), associated with a label (10) to be made; each reference image (12) being adapted to show the reciprocal position of every second decorating pattern (4) with respect to the first woven pattern (2); storing the picture in an association database (14).

Abstract: A method for coding and decoding information (10) associated with an item includes the steps of coding the information (10) associated with the item through an encryption key (20) and a first encryption algorithm, so as to generate a code (50) associated with the information (10), the code being realized through at least one material, typically an ink, having predefined electric properties (30) and being readable and decryptable by applying a variable electric field, and of applying the code (50) to the item, wherein the method generates encrypted information (95) which can be obtained by encrypting variable information (70) through a second encryption algorithm which uses, as an encryption key, the information (10) associated with the item, and applies the variable information (70) to the item or to a second item associated with the item.

Abstract: A security film (10,11) includes a film (1) onto which an electric code (50) is applied, which is obtained by way of at least one ink having particular electric properties, the electric code (50) including digital information that can be extracted by using radio frequency.

Abstract: 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).
