Code from material – visible natural microstructure of the material
Although a same material is used for producing of each order of objects to be protected, a structure of the material is different for due to the natural variations in the raw material structure.
A digital image of the structure of the substrate of every protected item around a specific place (sign) is taken during the manufacturing process.
The image is utilized for a subsequent verification of the originality of the product.
Fast and highly accurate verification can be done 1:1 or 1:N
The verification rate is high even though the protected item (document, goods, label, packaging etc.) is worn out.
