I can’t decide if this is creepy or brilliant, but here’s a video of a guy implanting an RFID chip in his hand as a way to quickly open the safe in which he keeps his handgun.

He writes:
“I implanted a RFID chip in my hand. I injected the chip myself from supplies bought on the internet. This tag is readable from up to 2 inches from my hand.

I am currently using it to open my handgun safe for instant access. I can have a gun in hand in one second in blackness without fumbling with buttons or codes.”_

As someone who has small children and keeps a loaded handgun in the house, I can see where this might come in handy from a speed of deployment and safety standpoint. On the other hand (OK, I’ll stop the bad puns) do-it-yourself surgery seems like a pretty extreme solution.
