Reliable technology doesn't currently exist. - Der

What do you mean by reliable? That no current technologies exist to make it possible? Because there's a lot of groups who have already created working solutions: [quote]iGun Technology Corp. Edit Led by Jonathan Mossberg, iGun Technology Corporation has developed 12-gauge shotgun that uses magnetic spectrum token technology, similar in function to RFID, to secure the gun. The shotgun is activated when in close proximity to a ring worn on the trigger hand of the user. A 2013 report by the National Institute of Justice stated that iGun's product "could be considered the first personalized firearm to go beyond a prototype to an actual commercializable or production-ready product."[2][3] Mossberg trademarked the term "SmartGun".[4] Safe Gun Technology Co. Edit Safe Gun Technology Co., led by CEO Tom Lynch, is developing a variation on the traditional smart gun in the form of fingerprint retrofit kits for installation on home defense guns.[5] Their retrofit technology, once installed, required an authorized user's fingerprint to unlock the gun and make it ready to fire. Safe Gun Tech is currently field-testing their fingerprint retrofit kit on an AR-15 rifle. Kai Kloepfer Edit Ægen Technologies CEO Kai Kloepfer, a high school student in Boulder, Colorado, has a working smart gun prototype that uses a fingerprint sensor to unlock the firearms safety. It can be programmed to register a range of fingerprints so that the gun would be able to be used by all the members of a police force. This prototype also promises to reduce risk of accidental shootings.[6] Kai received special attention as a result of a video produced for Uproxx Tech, "Has This 18-Year-Old Created The World’s Safest Gun?[7]", which has received more than 20 million views across platforms. He was also featured in the New York Times in an article written by Nicholas Kristof, "Smart Guns Save Lives. So Where Are They?[8]" New Jersey Institute of Technology Edit New Jersey Institute of Technology (NJIT)'s smart gun relies on biometric sensors in the grip and trigger that can track a gun owner’s hand size, strength, and Dynamic grip style, also known as (DGR) Dynamic Grip Recognition. The gun is programmed to recognize only the owner or anyone whom the owner wishes to authorize.[9] TriggerSmart Edit TriggerSmart has developed a personalised childproof smart gun using radio frequency identification (RFID) technology. Basically, only the authorised user can fire the weapon and the gun is safe in the hands of a child or an intruder in the home. Triggersmart is an Irish company that patented and achieved a working prototype of a smart gun, or "personalized gun", that uses radio-frequency identification (RFID) technology.[10] TriggerSmart has also patented and developed Wide Area Control ( WAC) where weapons can be remotely enabled and disabled using various wireless protocols. Safe zones can be created around schools and airports so that only authorised guns can operate in the designated area. Alternatively, when authorised guns leave the authorised area they can be tracked and disabled outside the safe zone. GPS and GSM capability can be added so data regarding, where and when, fired can be recorded and electronic notifications be sent to authorised partners. WAC can also be employed to help prevent Green on Blue fire or so called 'Friendly fire'. Armatix Edit A German company, Armatix, has developed the Armatix iP1 pistol, which comes with a special wrist watch which uses radio frequencies to identify the user.[3][11] Metal Storm Edit Australian defense company Metal Storm made a prototype electronic smart gun called the O'Dwyer VLe. It utilized biometric authorizing technology and was the world's first 100% electronic handgun. It also incorporated Metal Storm's patented 'stacked projectile' technology, which, in cohesion with the nature of the weapon system itself, meant that there was no moving parts, no separate magazine, no ammunition feed, and it outstripped conventional firing systems.[12] Smart Tech Challenges Foundation Edit In 2013, the nonprofit Smart Tech Challenges Foundation was founded with the mission to foster innovation in firearm safety by Ron Conway. The Foundation awarded development grants to innovators including Jonathan Mossberg, Tom Lynch, Robert McNamara, Omer Kiyani, and Kai Kloepfer, who are building smart guns, smart safety accessories, and other smart firearms safety technologies. Magna-Trigger The Magna-Trigger system was developed by Joe Davis in 1975 for J-, K-, L-, & N-frame Smith & Wesson revolvers prevents the trigger from returning far enough to fire. It has proven reliable. This system will work ambidextrously, provided the magnetic rings used are worn on both hands.[13] Magloc Edit The Magloc conversion kit for 1911A1 pistols works by preventing the handgun from firing unless a magnetic ring worn by the user repels the magnetic blocking device installed inside the grip.[14] Once the system is activated using the matching magnetic ring, the owner can switch the over-ride switch to the on position and allow anyone to fire the pistol.[15][/quote]
