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.
Union Bank of Switzerland, through its subsidiary refinery, Argor-Heraeus SA, has applied 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.
