A little known fact is that tongues, just like fingers, carry important identifiable information about a person, just like the fingerprints on fingertips do. Each tongue is unique not only in shape and visible texture, but it’s also unique for each person. In other words, as similar as your tongue may seem to somebody else’s, it’s not the same, because it carries information, which is unique only to you and your organ. Your tongue’s texture can help others identify you just as though they would be using your fingerprints. And while this may sound unlikely, researchers are actually already developing machines based on 3D scanners that could scan and compare tongue print databases.
