We provide banknote authentication DOVID foil for central banks in countries around the world. Confidence in the value and authenticity of money is critical for trade and a functioning society. In particular, banknote solutions need mass secure production and authentication accessible to a significant number of people – all those who handle cash.

We provide world-class designs, manufacturing facilities, and project management which are perfectly adapted to the highly demanding banknote security challenges.

Our Alphagram™ technology is used on the 50, 100, 200 and 500 euro notes, and on the 100 Brazil Real, while our advanced nano-structure based technology, the DID™, protects the 500 and 1000 Philippines’ peso notes.

Currency, tax stamps, credit cards and other documents of value demand the highest levels of security, both in the design/technology of security features and their manufacture.
