The next patented security device is Holo-Sif by OeBS (Austrian Banknote & Security).  The device is one of a type using decoder cards and lenses.  As luck would have it, a test note friend of mine Martien Van De Ven  penned an excellent article in the latest International Bank Note Society Journal titled "Hidden Features in Test Notes".  This decoder and others by Joh. Enschede, Kurz, Louisenthal, and Jura were included.

Holo-SIF® (OeBS)

Security information is hidden in two layers.  A decoder lens reveals the information.
