That's the whole point of this next gen smart gun. So that won't happen. Again, statistics show that what is most likely to happen is not that someone will be robbed in a way that allows them to use their firearm, but that a family member will accidentally kill themselves or another in the household. That's what this is supposed to prevent, and if it can prevent that while overcoming any response time issues when fighting off an intruder, why wouldn't you want something like that?
No, proponents of this sort of absurd hobbling of a well understood range of mechanical devices with untold millions of examples in use ... are after any and every method they can trot out to make firearm ownership as onerous, expensive, and undesirable as possible. The gun being described won't have anywhere near the refined computing horsepower of an entry level phone, while even the most expensive ones fail fingerprint detection under anything but ideal conditions, and can get RF-swamped out of something like Bluetooth being reliable on the fly in a life or death situation. To say nothing of having a reliable, charged up battery. Idiotic. Everyone involved in these efforts know all of that. And it's why nanny-state leftists get so breathless at the thought of laws like New Jersey's: they cannot WAIT for traditional, reliable firearms to be banned, while their own law enforcement agencies insist that they not be held to the requirement to use these built-to-fail nightmares.
Your entire thesis (the "most people get killed by their own family's guns!" meme) has been debunked on its rhetorical face value for years. It's a preposterous statistic to deploy, even if you stipulate it as even close to meaningful. The number of such household deaths (the overwhelming majority of which are suicides) is utterly eclipsed by the hundreds of thousands of times a year that family owned firearms are used to stop or prevent violent crime (see the recent, third study in a row out of the FBI, or the one done under Obama by the CDC). Firearms that can be picked up by any member of the household - even with gloves or wet hands or while not being the Magic Ring Bearer - save more lives every year than all murderers take, using any weapon at all, by orders of magnitude. And virtually all non-suicide deaths employing a household gun are deaths involving illegally possessed guns kept by people who are legally barred from purchasing or possessing them, with the murders involved typically including third party criminal activity that enters the household.
Laws requiring everyone to own only badly secured, unreliable "smart" guns won't put a dent in the murderous activity of criminals who can build their own traditional firearms as has been done for centuries, or have access to a vast black market of stolen or illegally purchased guns in the tens of millions.
Don't kid yourself or try to kid anyone else about the viability of this technology outside of some extremely specific use cases. The main interest in them, legislatively, is the ability to chip away at our constitutionally protected right to self defense by making the tools of that defense wildly more expensive or for many, unobtainable. That regressive tax on self defense falls, of course, hardest on those who most need it: it's a tax on poor people and the minorities that are over-represented in that economic class and most often subject to the violent crime that legs gun owners currently prevent tens of thousands of times every week. The politicians who live in gated communities with protection details know all of this, but are sure it won't impact them. After all, their own armed guards will be exempt from any requirement to carry such hobbled firearms. Of course.
