Resumen:
This work introduces novel, non-cloneable chipless RFID tags designed for authentication, offering a solution to protect product brands, such as wine, liquor, oil, and other liquid products, from counterfeit practices. A unique spectral response of the embedded tag, created by depositing various conductive layers, can be achieved by combining its shape and sheet resistance. To accomplish this, a laser-induced graphene (LIG) layer is formed on a cork substrate (used as a graphene precursor), followed by an electroplating process to enhance conductivity. This paper presents a prototype scanner, designed to characterize the electromagnetic signature of the tags, compatible variable-sized wine bottles and cork stoppers. Preliminary results obtained with complex logo images demonstrate the feasibility of this technology.
