Simply Secure – The Visible Digital Seal for digital ID checks

Simply Secure – The Visible Digital Seal for digital ID checks

Unique document protection and digital ID checks made easy with the Visible Digital Seal. While passports and ID cards are usually equipped with highly sophisticated security features, other identity documents such as visas, emergency travel documents, vaccination certificates or visitor badges are often less well secured. With this secure barcode, OVD Kinegram provides a simple yet highly effective solution.

The Visible Digital Seal (VDS) is a highly secure barcode and printable seal that allows digital ID checks and protects paper-based or digital documents against misuse and counterfeiting. It contains the principal information of the respective document as well as a cryptographically secured digital signature that protects against data manipulation and ensures the authenticity. It warrants document integrity and is an essential tool in the strive to create secure documents.

Unlike more complex solutions such as RFID chips, a Visible Digital Seal or secure QR code can be easily printed on any document – for example social insurance cards, travel documents, vaccination certificates or visas. Within seconds and using a standard printer of your choice, the document is protected by a secure code which can then be easily and conveniently verified with any conventional smartphone or standard document reader, anywhere in the world.

  • Immediate security thanks to speedy and easy production
  • High level of protection against misuse and counterfeitinghighly economical solution for securing documents
  • This secure barcode solution is a highly cost effective, yet very secure means of ensuring that a document is authentic and has not been manipulated


Rapidly issued and conveniently printed, the VDS does not need any special know-how or equipment. Based on an interoperable standard set by the ICAO (International Civil Aviation Organization), it is the ideal solution to ensure document security and data integrity. For an additional layer of document security, the VDS can additionally be equipped with a KINEGRAM feature, for example to protect the holder’s photograph.

Customized Codes

Customized Codes

Customized 2D barcodes are an ideal solution for rapid, efficient protection of paper-based or digital documents against counterfeiting and falsification. OVD Kinegram is highly experienced in providing tailor-made solutions for every customer that are extremely secure against manipulation.

Other than standardized solutions, our customized codes are the right choice for limiting accessibility towards outsiders and unauthorized persons. They can only be authenticated by designated persons.

The customized secure code contains the principal information of a respective identity document plus any other information that the customer requests. A cryptographically secured digital signature protects the document against data manipulation and warrants its authenticity and integrity.

Customized codes can easily be printed on any sort of identity document for immediate and cost-effective protection. Social insurance cards, visitor badges, employee IDs or any other sort of identity papers can be instantly secured against manipulation and fraud. By choosing a customized code that differs from standardized international frameworks such as the VDS, highest levels of confidentiality and security are ensured. The code can only be accessed and read by a pre-determined group of persons, for example local law enforcement personnel.

Customers enjoy a maximum of freedom and flexibility when it comes to the code’s content and its protection, i.e. choice of signature protocol. In collaboration with each customer and our highly knowledgeable associates at KURZ Digital, we determine the optimal solution for each customer.

OVD Kinegram’s customized secure codes can be printed within seconds on any standard printer of your choice, instantly protecting documents. The codes can be adapted to any customer-specific smartphone app for easy and convenient authentication.
