Unfortunately, I’m seeing something like that as ENFORCED per law, for so called “security” reasons in say 30 years from now.

Everybody will have a chip deeply implanted, it will be biocompatible, largely redundant and distributed across your body, say across your bone marrow or even better tied to your glial cells when people are still foetus and growing with them in order not to have the spy intentionally removed in adultehood.

Imagine the potential for criminal investigation. Of course, it won’t prevent delegated crime, but there will be other techniques to extract the truth from you. As I said, welcome to HELL!
