Nano anti-counterfeit technology

Spot hologram anti-fake packaging label

A German company recently developed a new type of anti-counterfeit labeling system that uses laser beams to digitize data information in the form of micrometer-sized light spots and identify the authenticity of products by identifying holograms formed by light spots. This new type of anti-counterfeiting label It has broad application prospects in the fields of products and packaging.

The new system combines the advantages of data storage technology for holograms and polymeric materials. The laser beam is used to burn a random number of light spots on a film of polymer material that is only 20,000 m thick. The film can be branded per square millimeter. One million light spots, these spots form a three-dimensional hologram that represents an image, a digital code, or a corporate identity. In addition, 1,000 points of data information can be stored in the spot, more than 1000 times the current capacity of the bar code, to introduce the product. In use, the hologram is reproduced through a special reading device and a laser beam, and the product information stored in the light spot is read out.

Although holograms on the market have been applied in anti-counterfeiting technology, because the traditional anti-counterfeit measures use printing technology, and there is no difference between the anti-counterfeiting labels of similar products, it has been unable to adapt to anti-counterfeiting needs. In contrast, the new tag anti-counterfeiting system uses randomly generated light spots, making the holograms of each tag different, and the spot itself also stores specific information, making the identification of counterfeit and inferior products more accurate and convenient.

Multi-layer color change security material

This is a process for the production of photochromic anti-counterfeiting materials at a low cost. First, the film system is designed with a computer according to the purpose and color change requirements of the security material, and then the physical vapor deposition method and the sol coating method are closely combined to complete the process at least. Reflective layer, dielectric layer, absorbent layer and other three layers constitute the production steps of security materials. The process of the invention not only greatly reduces the production cost, but also the refractive index of the nano-sol dielectric film can be easily changed by changing the composition of the nano-sol. Therefore, the use of color-changing materials has a wide range of choices for discoloration, and can be widely used in public security, expert anti-counterfeiting or a combination of security film or security ink.

"Nano Refraction" anti-counterfeiting mark

As the world’s largest independent memory manufacturer, Kingston announced that Kingston’s products all use the new “Nano Refraction” anti-counterfeit label, and gradually replace the two-year-old “Fluorescent Text Message” anti-counterfeit label.

"Nano-refractive" is called "Nano-glass microcrystal refracted ray" technology. It can display different texts and patterns under different light angles. If you place it under 40x magnification, you can see a series of overlapping combinations. Spherical crystals, this technology is currently used for the first time in the domestic memory area. Compared to the previous generation of "Flash Text" security tags, "Nano Refractive" security tags do not require third-party tools such as counterfeit pens, telephones, or mobile phones. Consumers can simply change the angle according to the anti-counterfeiting steps on the packaging and visually detect them. The first time to accurately identify the authenticity of the product, convenience and timeliness are greatly improved, at the same time, compared with the laser holographic anti-counterfeit label which has certain similarities but it has a longer launch time and lack of technology. "Nano-refraction" security marks have been improved qualitatively in anti-counterfeiting. The new technology itself has high monopolisticity and high technical barriers. Counterfeiters will be extremely difficult to follow up either technically or cost-effectively. Possible counterfeiting.

It is reported that in the future, all Kingston memory and flash memory products will adopt the new “Nano Refraction” anti-counterfeiting mark, and at the same time, the corresponding “Nano Refraction” anti-counterfeiting steps will be printed at the location of the product packaging, plus the product manufacturer Kingscon launched last year. The unique patented "color-changing anti-counterfeiting standard" and "one-minute online authentication" are two kinds of anti-counterfeiting measures. Authentic Kingston memory and flash memory products will build an all-dimensional, three-dimensional, high-tech triple comprehensive anti-counterfeiting system. Let counterfeiters fail to follow suit.
