Counterfeit products are a big problem for all kinds of enterprises. Regularly clone clothes, wallets, software and many other products. It is estimated that the annual revenue loss has reached hundreds of billions of dollars, and the problem has become so widespread. Amazon and eBay have stepped up the crackdown on counterfeit products.
Manufacturers also try to mark products with holograms, RFID or other hard to duplicate technologies, thus hamper forgery. However, camouflage has been able to find ways to recreate these ways. Fortunately, a method may end the counterfeit behavior completely.
Researchers have developed a way to use graphene or other two-dimensional materials to verify products. Quantum technology can mark products with unique "fingerprints" at the atomic level. Consumers and even dealers will be able to use smartphones to scan labels on items and run the label in the manufacturer's database to see whether it is true or false.
The technology is "non cloned". It depends on the laws of physics and copies it must be able to be built at atomic level, which is not possible at present. Its working principle is related to how to form graphene and other crystal structures.
Graphene is the lattice of only one atom thick carbon molecule. It is considered a miracle material because it is stronger than steel and is as flexible as plastic, but its crystal structure makes it an ideal choice for authentication. The technology developed by researchers plays a role in identifying irregularities in two-dimensional materials.
In "dense packing" materials such as crystals, molecules are arranged in a lattice structure stacked on top of each other. Because of the difference in the arrangement of small particles, perfect lattice will never be formed.
Just like ball bearings, atoms in two-dimensional materials produce similar defects. Because every part of graphene has its own irregularity, it is virtually impossible to repeat it. Most importantly, it can be applied to any surface, so clothes, smartphones, or any other material that is made of any other material can benefit from it, even money.
