The first generation of chips will indeed not provide the capability of tracking. But what about the next versions? the important thing is to get the people accustomed to chipping. If that happens, then the next generation of chips will have more capabilities, and finally they will include tracking of the person.


Well, no.

Tracking of the person would require something that you can't get from an implant - range.

Luckily, you're a nasty environment to signal from - you're mostly a bag of conductive electrolytes. It's like signaling from under the ocean - the path loss is spectacular, not to mention you are a huge impedance step change from air. That pretty much precludes any easy solution for a radio type tag (e-field part) since you tend to dissipate RF. The h-field type implants like verichip don't have dissipation issues but have no range. It's a physics thing.

Yes you are right, they were encouraged in states like Florida where the Issue of people not evacuating their homes during natural disasters posted the question of how will they be identify in case of accidents.

I remember.

Now for children and older citizens it could be a way to track them as we already have GPS systems in our cars and telephones.

In the UK it was a promoting campaign of chips to tell people when to take their medications.

So I thing that the technology is there but is not into the public yet, in full scale.

It doesn't work that way. You can't "track" an implant - they don't have any power of their own, they borrow a tiny bit from the interrogator. They don't even really transmit radio signals, they just throw a load onto and off of the pickup coil, the interrogator sees it as a tiny change in the output coil load.

Since they're h-field parts, the power density falls off as the sixth power of the distance from the interrogator, so the range over which they can operate is quite short.

In short, they don't use radio waves (despite the term "radio frequency" in the name), they don't actually transmit, they have no internal power, and you couldn't embed a GPS device in a person anyway. The entire "GPS implant" meme is bogus. But it sounds all spooky, so it lives on.
