Fake money, fake clothes, discoverd with your smartphone and QRcoda

The university of South Dakota have developed a new Type of QR-code invisible, ready to application on any material. The system is based on nanoparticles tecnology and is used to discovered fake material. The technology could come soon in the industrial process.

The Quick Response code a monochrome square, when is scanned with smartphone, directs to specific content sites, they do not have become a mass phenomenon. The recent smartphones, with “Near Field” recognition devices have inflicted another blow to QRcode. Yet they survive, and they might have found their raison d’etre in a U.S. study.

The university of South Dakota have developed a new Type of QR-code invisible, ready for, once in production, to an infinite number of products. Paper, textiles, plastics, glass, stone, all receptors are ideal for the new generation of QR. But in addition to the known uses, these new codes can function as a digital watermark, carrying out an authentication function, as well as data recovery. The human eye can not detect them, and become visible to infrared light. It could represent a system of identification to distinguish fake money from real banknotes, documents and counterfeit clothes: simply point your smartphone – if it has an infrared vision – and this instantly recognize what the user is facing.

The University of South Dakota also specifies that these new codes are, unlike the QR-Code classics rather difficult to duplicate, because of the complexity of processing. They are created using nanoparticles combined with blue and green fluorescent inks, and printed on the surface to be treated with a printer of aerosols. A process that takes about an hour and a half but that industrial regime, the researchers say, may not take more than 15 minutes.

You can easy modify the code by inserting more information or data not readable by common tools, in order to provide an element of use, even for legal uses. It may not be the end of counterfeiting, but the revenge of the QR-Code seems to be significant.
