Wouldn’t the body reject them, and/or get infected around the implant area?
We already implant subdermal RFID chips in animals and people. You just put the chip inside a non-biologically reactive substance and it’s fine.
The bigger problem is scanning distance. You’re limited to only a dozen meters or so if you’re not using an active RFID with battery. ~100 meters with a battery but then you have to change the battery every now and then.
I’ve had a toll pass device for 10 years. It gets scanned at 80mph or more and hasn’t needed a new battery yet. The newest models are the size of a credit card.
Yeah but radio doesn’t like meat shields being in the way. The frequencies normally used in RFID only penetrate a few cm into people.
I guess we could always advocate for RFID tattoos if we really wanted to get this going.
They’re also probably broadcasting at powers not safe for humans to constantly be around, only for the 1/10th of a second you pass under.
Yeah, it goes through just about any material. I used to keep one under my seat on my motorcycle. So it would scan through me, the rubber/foam/whatever seat and into the metal box under my ass. That was 10+ years ago in the Orlando area, I can’t imagine they have gotten less accurate
I just got one that’s literally a sticker stuck to the inside of my windshield

Implants that don’t get rejected exist. Either medical or as body art or even by cyber enthusiasts. I’d say even a piercing would qualify as a type of implant. So I guess if you know what you’re doing you can get around the infection topic.
Forget that, what powers them? Something that can be read with a close by scanner makes some since since I figure you could induce a current in one, but the kind you sometimes see in movies that constantly sends out a signal that some satellite can clearly track anywhere in the world, and do so for days, weeks, months or longer, would need one heck of a battery I’d imagine? And in a very small space too
Bring back RTGs! They’ve already proven their use in pacemakers.
Pacemakers have batteries and modern ones broadcast a lot of telemetry, and last up to a decade. Not sure how much more power would be needed to broadcast to a satellite or cell tower though.
Subdermal is a lot easier than implanting in other compartments, e.g., intracranial. For example, hormonal birth control exists as an implant.
But, there’s fascinating research into how the brain rejects implanted electrodes, e.g., neuralink. Lots of work has been done developing materials that are less likely to be rejected by the brain and the brain’s immune system. For example, electrodes can be coated in chemicals to make them less harsh to the body, and flexible materials can be used.
We also have subcutaneous birth control that doesn’t get rejected.
Many materials are biologically inert. Titanium, for example, is often used for replacement joints and doesn’t need anti-rejection drugs. They autoclave or otherwise sterilise things during the operation, so the infection risk is pretty much the same as for any other kind of operation.
artificial organs, that birth control rods in the arm, I have a hernia mesh in me right now and I did not have to take immune surpressors and neither did my wife with an artificial hip (which did get infected) and screws in the knee oh and a plate in her skull. screwing artifical teeth into jaws is very common now to. Seems like a little subdermal implant would be no were near as bad as these common practices.
I think this is asking if something seen in movies could happen in real life, but I first read it as getting something implanted when going to see a movie and couldn’t figure out why no one was asking why you would do this.
Yes
