The Internet of Things is evolving into a world of interconnected smart devices that communicate all manner of information. Smart homes can be filled with appliances that can be controlled remotely, while the smart grid promises to dynamically react to power requirements.
Cities are also turning smart. Systems already exist for using mobile phones to pay for parking on city streets, video cameras monitor crowd control and safety at large events, and acoustic detection is used by police departments to identify gunfire.
The gun itself has a smart progression. Smart guns can identify authorized users with RFID chips, fingerprint recognition, magnetic rings, or mechanical locks. The security features are designed to prevent misuse, accidental shootings, gun thefts, and use of the weapon against the owner.
