QR-Check TunTrust

The National Agency of Electronic Certification TUNTRUST sets up the device stamp Electronics Visible TN CEV 2D-Doc for securing electronic documents and paper through a bar code in two dimensions (2D-Doc) incorporating the electronic signature of the transmitter.

This solution allows to seal the key data contained in a document through an electronic signature made visible through a QR code (bar code in two dimensions). Thus, condensate key data is calculated and then signed by the electronic seal certificate TN CEV 2D-Doc of the investee. Key data and signed condensate are incorporated into the QR Code affixed to the document as a stamp Electronics Visible to ensure the integrity and authenticity of your documents.
