Depth perception in modern banknote security

Nanotech Security Corp., a Vancouver-based developer of nano-optic security features used in the government, banknote and brand-protection markets, participated in this week’s Holography Conference Online.

Focusing on technical and scientific developments, the annual Holography Conference is the only global conference for the commercial holography industry.

On Dec. 9, as part of the event’s first virtual gathering, Nanotech Chief Technology Officer Clint Landrock presented “The Importance of 3D Stereo Depth in Authentication.” While exploring depth perception and its importance in verification, Landrock highlighted Nanotech’s “KolourDepth” security foils and stripes, which boast 3D stereo depth, movement and multiple colours to provide fast and easy visual authentication of banknotes and other secure items.

According to Nanotech’s fourth-quarter financial report issued yesterday, the company’s management “is in the process of qualifying a world class OEM (original equipment manufacturer) manufacturing partner for its KolourDepth products” in the government and banknote market. Qualification is expected to be complete in the second quarter of the next fiscal year.

“Depth is an important authentication tool for security features as it supports excellent authentication within a brief viewing period, performs well under low illumination and is readily visible when static,” said Nanotech President and CEO Troy Bullock. “3D stereo depth holds great promise for governments and central banks to consider when looking for new security features.”
