QrCertCode App allows you to verify the accuracy and completeness of a document or a set of documents in analog format (printed on paper) against the original digital version. How does it work? If the document features a QR Code with the QR-CertCode and IAC logos, it means that a legally certified digital copy of the original document exists, in accordance with the CAD (Digital Administration Code) regulations. By scanning the QR code with the app, you can access the certified digital copy and verify its exact correspondence with the printed version being reviewed.
