What is VDS?
The Visible Digital Seal (VDS) is a 2D barcode technology that ensures the authenticity and integrity of information on documents and objects. Based on open, international standards (ISO 22376 & ISO 22385), VDS provides a secure, interoperable solution for document authentication.
User Experience
Verifying a document's authenticity has never been easier. Scan the Visible Digital Seal with the Otentik Reader app — the result is displayed instantly on screen. No technical expertise required, no special equipment: your smartphone is all you need. For industrial environments, VDS also integrates with existing 2D barcode and RFID readers.
Otentik Code Reader
Otentik Code Reader is the free Visible Digital Seal (VDS) and 2D-Doc reader. Scan a document's code: the app checks its signature, issuer and revocation, then shows the certified data. No account, no data collection. Available on App Store and Google Play.
