The beauty of this is the ability to create a unique QD signature for the product manufacturing facility. It can go to each product type if needed but I don't see that detail being needed at this point.
Point two would require the knowledge of the composition used to make the specific (uncopiable) color signature. They would need to know if they are round or tetrapods and the composition make up that gives the specific generated wavelength.
They can be duplicated as long as you know the composition makeup, have the equipment to do it, know the layer sequence and the pattern configuration. Other than that it's pretty simple to do.
