The invention relates to a method for forgery-proof labeling of items, such as credit cards, bank notes and the like, comprising the following steps: (a) applying, to a first layer (1) that reflects electromagnetic waves, an inert second layer (3) that is permeable to electromagnetic waves, said second layer having a predetermined thickness, (b) applying, to said second layer (3), a third layer (4) that is formed by metal clusters, and (c) linking the first layer (1) of the label so produced with the item.
L'invention concerne un procédé pour marquer de façon infalsifiable des objets, tels que des cartes bancaires, des billets de banque et des objets analogues. Selon ledit procédé: a) on applique, sur une première couche (1) réfléchissant les ondes électromagnétiques, une deuxième couche (3), inerte, qui laisse passer les ondes électromagnétiques et dont l'épaisseur est prédéterminée; (b) on applique sur la deuxième couche (3), une troisième couche (4), constituée de clatrates métalliques; et (c) on lie la première couche (1) du marquage ainsi formé avec l'objet.
