1TrueId s.r.l., in collaboration with Mood s.r.l., WWG s.r.l. and Politecnico di Milano has undertaken an R&D project whose goal is to be able to trace the origin of a garment in a simple and immediate way, through the use of technological devices, describing in detail every step that concerns that garment and highlighting the sustainability aspects. Through this project, the history of the garment, from the cultivation of the raw material to all the uses and re-uses after marketing, will be fully certified by borrowing the Block Chain method from the financial system and applying it to the fashion and production of clothing. All this information will be made available to the consumer through an NFC TAG device, which will allow and facilitate the reading directly on a smartphone. The purchase, at this point, will become aware, ethical, ecological and responsible.
