2D-Doc barcodes are increasingly present in our lives. They are found on documents as diverse as Crit-Air certificates for cars, certificates of residence or other, invoices from certain suppliers, hunting permits, notices from the administration, the new identity card, etc. ..
These barcodes contain coded data as well as a signature which makes it possible to fight against document fraud while ensuring the security of online services.
Conventional barcode readers can only read the data encoded in the barcode, which gives no indication of the content of the code (the data and its values), its conformity (meets the specification) or its integrity (the signature is valid).
This application allows you to fully interpret and verify these 2D-Doc barcodes.
Unlike other applications of this type, the validation is entirely done by your device without any data being transmitted to an external server. Your privacy is thus fully preserved.
Currently, this application can read all documents compliant with the ANTS specification V3.2.6 (https://ants.gouv.fr/nos-missions/les-solutions-numeriques/2d-doc) except the very rare codes -bars in version 4 Binary.
This application does not collect any personal data and is guaranteed without any trackers.
