Wouldn’t the body reject them, and/or get infected around the implant area?
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
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.
I think this is asking if something seen in movies could happen in real life, but I read it at first 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

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. RFID only penetrates like a few cm into people.
We could always advocate for RFID tattoos if we want to get this going.

I just got one that’s literally a sticker stuck to the inside of my windshield
