Biometric locks
For me, I'm still trying to talk them out of them where I sell the personal safes at work. We carry Liberty and StackOn with fingerprint scanners, and I've been testing them daily to see if they'll consistently open for me. I think they're especially bad for this, as one may need to get one's defense gun out quickly in an emergency. I get really dry chapped skin on my fingertips a few times a year (like right now) and it pretty much guarantees I won't be able to open any of them about 60% of the time. There also seem to be a lot of fairly easy ways to fool them, and now theres an AI that can apparently create fingerprints that work like a master key for all of them.
This kinda leads into a deeper discussion about electronic/networked/IoT locks and whether adding so many additional levels of vulnerability to a mechanical lock is really helping anything. I guess it's super convenient to be able to unlock your house with your iPhone or whatever, but it sure makes it convenient for hackers at the same time, and coming from a background of web security, I'm not convinced we're ready for the potential exploits.
Thoughts?
