NPR:

In Sweden, a country rich with technological advancement, thousands have had microchips inserted into their hands.

The chips are designed to speed up users' daily routines and make their lives more convenient — accessing their homes, offices and gyms is as easy as swiping their hands against digital readers.

They also can be used to store emergency contact details, social media profiles or e-tickets for events and rail journeys within Sweden.

Would you place the implant in your thumb, pointer finger, or middle finger?

    I wonder if they somewhat easily could be read and cloned onto another chip. That could be entertaining if said chip is the only security feature used and you just got yourself an instant double that can't be told apart from you since your only security feature is a chip you implanted into your hand.

    That's a good question. But in theory, if the chip is designed to communicate and cryptographically sign messages, this could be made nearly impossible. Of course it wouldn't stop someone from chopping up your hand to get at the chip, or someday breaking the algorithm (which presumably would require surgery to update).

    I would wonder how power would get to the chip though to power it up to do cryptographic signing. Maybe an inductive coil? But I'm curious how voltage regulation here would work. I assume it'd be a linear regulator as I don't think there'd be enough room for a buck converter in the chip. So it could get hot? But maybe if only used briefly that wouldn't be a problem.

    Probably this chip is less secure, but there's no reason in theory why the chip couldn't do ed25519 signing or something of that nature, which would make it rather hard to crack.
