How are documents certified as compliant? How are security certificates installed?

By adding a 2D-Doc Visible Digital Seal to documents, SmartStamp.io makes security accessible to anyone for all paper or electronic documents. With an easy-to-verify code, the stand-alone system makes it possible to certify a document such as an invoice as compliant based on the data presented. Invented by ARIADNEXT, the 2D-Doc Visible Digital Seal is a simple, effective way of fighting all types of document fraud. ARIADNEXT is the first French certificate authority officially recognised by the ANTS and authorised to issue 2D-Doc certificates.
