Abstract:
The present invention is directed to a method for authenticating a package using a magnetophoretic imaging film. It provides a low-cost method for verifying the authenticity of products in a way that is not immediately evident to counterfeiters. A single pre-patterned magnetic image can be used to display images on any number of individual imaging films.
