Will the “smart gun” have a keypad to punch in a passcode when the fingerprint sensor doesn’t work?
That shouldn’t be a problem. All you have to do is ask the burglar or assailant to wait a moment while you punch in the code.
Can’t tell you how many times my finger print does NOT work on my phone and iPad, I sure would hat to be in a stressful situation trying to punch in a code NO THANKS!!!
