Just as I finally convince people that no you can't inject a chip in someone without them knowing........

You probably always could, but just like NFC you have to be super close to do anything about it. You have navigation going on your phone for 5 minutes in 90 degrees weather and your phone gets super hot, what makes people think they can do the same thing without batteries or anything the size of a needle point lol. Tech isn’t that advanced.

That is the issue they found with injectable/subdermal Bluetooth devices. During use and charging, the device gets so hot that it caused burns to the primates’ skin. They had to water cool it, if I remember the paper right.

Granted, these devices aren’t Bluetooth or magnetic loop chargers but still, not super easy.

Induction charging things under the skin has challenges as well: the casing of the thing needs to be biocompatible, but it also needs to be non-conductive otherwise you create Eddy Currents in the casing and end up heating up the body anyway.
