Nano-Optical Elements for Physical Security of Tax Stamps

Excise tax stamps are valuable documents because they are used to regulate the production, distribution and consumption of a certain group of goods like alcohol and cigarettes and confirm payment of excise duty. Therefore, not only the products, but also the stamps themselves have value and are the subject of counterfeiting and falsification. However, the tax stamp industry faces many challenges, such as the increasing sophistication and diversity of counterfeiters, and the emergence of new technologies. Therefore, there is a need for innovative and effective solutions to enhance the security, efficiency, and revenue collection of excise taxation. The use of holograms for tax stamps is an innovative and effective solution to enhance the security, efficiency, and revenue collection of excise taxation. Tax stamps with holographic protection have been successfully used for several decades and the market for tax stamps is estimated at more than $30 billion.
