Countermark for Documents lets you annotate, validate or protect all types of documentation.

A Countermark can show selections of visual and printed data to send to a phone. The image of the Countermark code is in .png format which can be added to Microsoft Office, Adobe Acrobat and many other types of document.  Using the Countermark App you can restrict where, when and who can read the Countermark.

When you add a Countermark code to a document, the Countermark operates like a hyperlink and adds data that is not apparent on the document. Examples include:

• Title blocks on drawings or sensitive data on specifications
• Audio clips on exhibition signage
• Links to social media on garment tags
• Links to YouTube or Amazon shops on concert tickets
