Abstract
The present invention relates to a method for producing radio frequency identification devices (RFID) without personalized chip, in particular the production of RFID tags without personalized chip, also referred to as chipless RFID tags. The present invention also relates to devices and labels produced by the claimed method as well as to systems for producing said devices/labels.
Claims18
A chipless radiofrequency identification device, said device being characterized by a multilayer composition comprising
- a substrate,
- a pattern printed digitally on the substrate and consisting of a printing product comprising an ink, a varnish and/or a toner,
- an identical pattern superimposed on the printed pattern and consisting of a conductive film comprising an application film layer in contact with the printing product and a conductive film layer, the conductive film configured to reflect a radiofrequency signature indicative of information coded on the chipless radiofrequency identification device only by resonant backscattering of the conductive film.
A method for manufacturing a chipless radiofrequency identification device including a multilayer composition comprising a substrate, the method comprising:
- a step of digitally printing a pattern on the substrate by printing a printing product comprising an ink, a varnish and/or a toner,
- followed by a step of selectively depositing a conductive film on the printed pattern through contact between the printing product and the application film layer of the conductive film comprising an application film layer in contact with the printing product and a conductive film layer, the conductive film configured to reflect a radiofrequency signature indicative of information coded on the chipless radiofrequency identification device only by resonant backscattering of the conductive film.
