Small holes are laser perforated through the document to form a unique legible number. It can be easy used as first level of inspection, as the laser perforation personalizes a document, and can be easy cross-checked with the printed number. The laser numeration security feature can be used to secure other security features on the document (such as holograms) preventing possibility to use them for document forgery. Laser numeration security feature can additionally improved with our patented solution – encrypted marking (link), or it can be done with different shapes of the perforation hole. Laser numeration security feature can be used to protect any kind of document (passport, banknote, visa, ID card etc) or for brand protection on a product that has numbering.
