varifeye® C2 Secure Window for multi-view authentication
The appeal of varifeye C2 Secure Window stems from a striking change of colors and images when viewed in different situations and at different angles:
- Tilt effect in reflected light:
color shift when the note is tilted
- In reflected / transmitted light:
change of image from e. g. number to motif (35 to anchor)
This optically variable feature makes it much easier for consumers to authenticate banknotes. Due to its state-of-the-art foil-processing technology varifeye C2 is secure against counterfeiting.
Embedding the window design in the overall foil element and banknote design boosts even more the level of security and attractiveness of a banknote.
