The nano4U group of companies was founded in 2008 to bring widely applicable high-technology product security and authentication solutions to industry. 


Our cutting edge production technologies mark and authenticate products or packaging directly, including the use of nano-structuring techniques. These methods allow multilayer security features and anti-counterfeiting technology such as machine readable covert or overt coding and special visualisation optics. In general we modify production tooling so that the application of the features does not add additional costs or complexity in the industrial mass manufacturing process of our clients.


Based in Germany and Switzerland, the company employs technologies including methods developed from those originally used for the authentication of banknotes. A portfolio of intellectual property focused on security and anti-counterfeiting technology supports the company’s capabilities. In addition to applications in mass production industrial processes, nano4U is actively involved in ongoing research and development with co-operation partners in academia and industry.
