SYSTEM AND METHOD FOR TAGGING A PRODUCT, ASSOCIATED CERTIFICATION METHOD AND TAGGING PRODUCTS

摘要

What is described is a tagging system which comprises a material adapted to be associated with a product, such as a commercial product, an article, or the like. This material includes a base polymer matrix, adapted to provide a spectrum of response to one or more predetermined incident electromagnetic radiations, and at least one additive substance incorporated into a predetermined marking zone of the material. This additive substance is adapted to cause a modification of at least one characteristic of the response spectrum of the base matrix. The system also comprises a reference instructive item, for providing information correlated with at least one characteristic of the said modified spectrum. The information provided by the reference item is compared with corresponding information obtained from a spectral analysis of the material associated with the product in a method of certification of the product. Also described are a tagging method based on the aforesaid system, a method of certification of a product tagged in this way, and tagging products such as a package, a label, an article, a textile, a varnish, paint or ink, and an adhesive product or sealant.
