The Fingerprint AlpVision technology enables to authenticate molded or die stamped parts using just an iPhone. This authentication solution covers for instance plastic parts obtained by injection molding like caps, circuit breakers, flip-off caps, as well as metallic parts like those obtained by die stamping on metallic parts for the automotive industry. Until recently, this technology required to acquire an image of about 20mmx20mm of the object to be authenticated. However, we were recently able to adapt the algorithms and image processing routines in order to work with some macro lenses that are readily available for the iPhone. This enables to authenticate areas almost 10 times smaller and opens our solution to an even wider field of applications including for instance luxury watches.
