Abstract: A system and a method for authenticating and certifying a physical item are provided. The system has an identification tag coupled to the physical item and having a relevant tag identifier adapted to be read at a distance, a non-fungible cryptographic token issued on a predetermined digital register distributed in a plurality of nodes of a processor network and configured to store the relevant tag identifier of the identification tag coupled to the physical item and data or information representative of the physical item, and detectors for detecting the presence of the identification tag of the physical item passing nearby a predetermined detection area or through a predetermined detection gate. Data indicative of the presence of the physical item in the predetermined area or the physical item passing through the predetermined gate is recorded in the non-fungible cryptographic token. The physical item may be a garment, a sportswear item, a collectible, or a luxury item.
