ZZZZzzz,
You migh not have known but Optical Thin Film (OTF) has been around for a long time. It was Bank of Canada's technology - they used to own it. It was sold to Fortress Paper in 2011. So it was around even before then, and first used in 1988 before making more maintstream in the 90's. Nanotech bought OTF from Fortress in 5 years ago in 2014. So in hindsight, Troy's reference to twenty years of having OTF as a reliable security feature is correct.
I do agree with you on everything else. All talk and no action. I've been invested in the company since 2011. Banknotes was the wrong first direction, in my opinion. They should have tackled brand recognition and protection of consumer goods first.
