This information, including product codes, product names or requested content, cannot be seen by the naked eye or through common devices such as QR code scanners or UV scanners. Quantum nanoparticles are very small nanoparticles, usually only a few nanometers in size, with special electronic and optical properties brought about by the quantum effect. When illuminated, quantum nanoparticles have the ability to emit strong luminescence and can change the color of the emitted light by adjusting the particle size.

MINA Anti-Counterfeiting Technology Joint Stock Company has applied this technology to develop anti-counterfeiting stamps with a two-layer structure: layer 1 protects the outside with QR code, and layer 2 protects the inside with electronic nano ink, helping to hide information that cannot be detected by the naked eye.

A stamped product carries only one code, including a hidden code and a visible code. The visible code allows consumers to look up the accuracy of the product, while the hidden code helps businesses verify and check the accuracy when necessary. Using MINA's specialized equipment allows for quick checking of sales agent information, identifying counterfeit status, thereby helping businesses effectively manage and control counterfeiting, limiting different usage behaviors to distinguish customers, in order to maximize profits.
