Kinebar

A kinebar is a gold bar which contains a Kinegram to prove its authenticity. Kinegram is a trademark of OVD Kinegram Corp. (Switzerland). A kinegram is a diffractive security device embossed into a substrate (here gold). It is intended both as a security feature and for visual appeal. Note that a Kinegram is not a hologram; a Kinegram displays a flat diffractive design, while a hologram is a diffractive device that displays a three-dimensional image.
