What is a Countermark?

A Countermark comprises a 32-character alpha-numeric string which is easy-to-read with software and the human eye:

A dedicated mobile phone App, with links to the Countermark server, is used to read the Countermark and return the original data to the User. The Countermark fonts are optimised for machine reading.  The fonts are registered designs and the name Countermark and the Countermark key symbol are registered trademarks. International patents protect the Countermark reading algorithms.

The data returned to the Users can be a PDF file, a link to a web page or a static image which can contain words and pictures or both. In the future, the ability to send audio, video and links to social media to the User’s phone will be added.

You can print Countermarks in Latin, Cyrillic, Katakana and Chinese fonts:
