The Idea of a Biometric Scanner Has Been in Existence Since the 80s
Star Wars was the first movie who made use of the concept of biometric scanners. They were used to gain access to every entrance in the space ship of Darth Vader. Aliens and humans alike had to press their hand unto the biometric scanner. If the device will be able to recognize the hand that was pressed on the device, the door will open. If it does not recognize the identity of the person (or the alien), the alarm would ring and guards will rush to the area. That was back in the 80s. Steven Spielberg, back then, was already futuristic when it comes to his movies.
Who would have thought that the gadgets used in a science fiction movie back in the 80s are being used today. It is the perfect example of a dream that has become a reality. It would have been cool too if we also use space shuttles to bring us back and forth in our destinations or at least flying cars. Who knows? Maybe after a decade or so, it will become possible.
