A digital handgun with an electronic safety that can automatically be disabled via wristwatch sounds like something out of Minority Report. The high-tech watch requires fingerprint authorization from the primary owner, which is then analyzed through the device's internal database and becomes activated for a restricted time period or until it's manually deactivated. After registering the wireless signal sent from the watch, the revolver's LED light on the back flashes green (unlocked) or red (locked) to inform the user of the gun's initial setting. Sounds like the perfect weapon for law enforcement.
