Secure Windows

Security has never looked so appealing!

Louisenthal’s pioneering spirit has produced a major – and exclusive – innovation: a transparent window with a striking colour change from gold to blue. It allows users to verify the note from front to back – and that’s an industry first.

This front-to-back verification encourages the public to check both sides of the banknote, making it possible for them to identify the authenticity with ease. Our varifeye® security windows can be combined with foils in multiple metallic effects, resulting in a unique look that users can recognize instantly. As well as the window, they see the hologram, micromirrors, 3D elements or other design below, which can also change its size or shape depending on the viewing angle.
