ENIGMA^™ 
Our invisible high security taggant feature. 

ENIGMA™ is a 3rd generation covert, machine-readable taggant that is reserved exclusively for central bank use and serves as the last line of defence in the event of a serious counterfeit attack.

Evaluation by two G7 central banks failed to reverse engineer this feature. A truly covert feature; it is the only banknote feature available for paper banknotes that serves exclusively as a level 3 feature.
