High Security Tax Stamps

Secure Tax Stamps for Protected Goods

Counterfeit alcohol, cigarettes, documents, restricted medication, cannabis etc. cost governments billions of dollars annually in lost tax revenue, worldwide. The need for innovative, hard to replicate security solutions is a priority for governments and individuals alike. Tax stamps now require robust anti-counterfeiting technology solutions in order to protect from counterfeits. These illegal goods can also be dangerous to the public as they may include substandard ingredients including potentially dangerous chemicals that could cause loss of life or serious illness. Nanotech enables governments to guarantee the authenticity of these ‘counterfeit prone’ goods by creating a high security nano-optic tax stamp that is easy for the public to validate and extremely difficult to copy.

Our Solution

A new form of nano-optics, created by Nanotech, has changed the security market by being virtually impossible to replicate without using multi-million dollar Electron Beam Lithography machines and decades of nano-optic experience. Our nano-optic security features help governments protect the public from counterfeit goods using solutions that are high resolution, durable, and can be applied onto various materials and substrates. Nanotech’s nanotechnology-based solutions contain unique visual effects and elements such as movement, on-off, on-invisible, 3D imagery and colour-shift that are customized for each government’s precise needs. Nanotech’s products are also compatible with common traceability applications (QR codes and track and trace programs) and other tax stamp elements such as intaglio printing. 




Based on Nanotech’s KolourOptik® nano-optic display technology, KolourDepth™ security features deliver movement, 3D depth, and multiple colours that offer a wide array of custom design options to capture and hold the user’s attention, and deliver reliable authentication of documents.

KolourDepth security foils and stripes utilize anti-counterfeiting technology that is easy to trigger and intuitive to authenticate. The combination of patented nano-scale origination, proprietary algorithms, and specialized nano-fabrication techniques result in a unique security feature that is nearly impossible to reproduce or reverse engineer.
