The money printers themselves are nothing that special. The secret to most of them is 'what' they do, maybe a little of 'how' they do it, but you can build your own as you know what it's doing. Consider that most countries have similar anti-counterfitting measures to the US.
Also, I remember a history channel documentary where when they talked about some of the suppliers to the BEP 'Family Owned for generations' came up at least once. Possible connections there?
