KINEGRAM REVIEW® is a window security feature that offers three security effects in the window area alone, two different optical foil designs on the front and back of the banknote, and a third see-through security feature: An image which becomes visible when the banknote is held up against the light. KINEGRAM REVIEW® is the undisputed best-in-class solution for windows in banknotes.
In combination with a foil stripe, windows are a perfect choice for easy authentication and extremely high anti-counterfeiting security. The foil operates as a two-sided security feature, resulting in a secure window. With a transmission as well as a reflection feature, the foil can be seen and identified from both sides of the banknote as well as offer a see-through window feature.
KINEGRAM REVIEW® thus offers front-to-back verification by showing different diffractive images seen from the front and from the reverse of a banknote. For example, the foil can display a diffractive portrait on the front of the note and a wallpaper design of the denomination on the reverse side. A registered image both on the front as well as the reverse side is possible, thanks to intensive R&D work. The partial metallization allows the viewer to see through the window.
Originally devised for paper banknotes, KINEGRAM REVIEW® can also be applied on polymer banknotes, which offer the benefit of enabling even larger transparent window areas. A variety of different foil designs for banknotes is available within a KINEGRAM REVIEW® foil feature.
