The picture shows a UBS kinebar (Argor-Heraeus) with certificate.
A kinebar is a gold bar with a kinegram on its reverse surface. This security device is similar to a hologram which depicts a 3d design, whereas a kinegram shows a 2d design. The kinegram is a registered trademark of OVB Kinegram Corp., Switzerland. UBS has used the kinegram on gold bars since 1993. The Argor-Heraeus kinebar is produced by UBS, as Argor-Heraeus is a subsidiary refinery of this company.
