We have a customer who wants to commercially print a unique target (image, ?) on their product, which once detected would trigger functionality in their mobile app. The customer prefers not to use QR Codes or Bar Codes, but they would potentially need hundreds of thousands of unique images. Does anyone have any ideas on what type of images could be used?
Also, their first idea was to implement user generated images with the target being a person's signature. We are assuming that the technology is not there yet to be able to use a person's signature (diffent wirting instruments, stoke widths, etc) - are we wrong about this assumption?
Any insights would be much appreciated.
Thanks in advance.
