Kinebar
A kinebar is a gold bar which contains a hologram to protect its authenticity. Kinebars use a hologram called a "kinegram", a diffractive optical variable image device which is embossed into the gold substrate. "Kinegram" is a trademark of OVD Kinegram AG. The hologram is intended both as a high-security feature and for visual appeal.
Union Bank of Switzerland, through Argor-Heraeus SA, has been applying the kinegram as a security device to the reverse of its minted bars since December 1993. The kinebar, now produced by UBS AG, is a registered trade mark of UBS.
