People  have been yapping on about “smart guns” for decades. Why can’t we have a pistol that only the owner can use? If we have smart phones with thumbprint readers, why can’t we have that tech in pistols? Well, there are good technological reasons… a thumb covered in sweat, dirt, oil, blood, etc. isn’t going to be conducive to 100% reliability in a device required to function 100% of the time. Wear gloves, and the thumbprint reader is right out. Similarly, devices that rely on magnetic or RFID systems built into rings, watches, surgical implants, etc. have a chance of failure or inavilability. But the biggest thing that has suppressed American firearm companies from even trying is politics. In particular, the Democrat Party of New Jersey passed a law that made it a dead certainty that nobody in their right mind would even try. An interesting (if predictably left-leaning) writeup of the issue is here:
