If the photo had sufficient resolution, yes, it could easily be done. BUT, it would have to be in focus and taken at close range which no regular cell phone or digital camera or even film camera will do. Their focal range is nowhere near the lens and not designed for closeups at that detail level. A long distance telescopic microscope might do it (they're used for examination of things that cannot be gotten close enough to easily and safely) but not everyone has one. A system designed for scanning surfaces would be more likely, and such are one variant of palm or finger print scanner, as well as document scanners and photocopiers.
