From the recent nano article QMC creates in com

QMC creates in commercial quantities quantum dots that can be finely tuned to emit predetermined wavelengths of light (in both the visible and non-visible spectrums) with the ability to create billions of unique optical signatures. Moreover, they are excitable by numerous excitation energy sources.
Our quantum dots can be incorporated into almost any physical item at time of manufacture and then provide a unique light signature that establishes absolute product identity. These identities are impossible to copy or clone so that products enhanced by them can be verified as being genuine items and not counterfeits.
When the quantum dot signature of a product is scanned (via a hand-held scanner or an app on a smartphone), a digital representation is created that is stored on our secure and tamper-proof blockchain platform. It is this platform that allows for tracking of products providing visibility among all participants in their supply chain - from manufacture to customer purchase.
In addition, the blockchain platform is also used to store the unique digital identities of individual customers, and to tie ownership of a product to a customer at purchase time. No longer is it necessary to keep the receipt!
The last statement would be great in my business where I am purchasing manufacturers products that carry warranties.Its hard to track every part installed in our Mechanical systems and this would make it very simplistic to know if a part installed is past warranty or not when dealing with a service issue..another benefit of this application.
