monitor there whereabouts in the same way a Vet can implant a chip to track your cat or dogs whereabouts?

Current RFID chips can only be read from a distance of about 3 inches. The signal produced by an RFID chip is not strong enough to be transmitted any further because of power consumption.
The tracker would have to know the location of the RFID chip located with the person's body and they would need to get a scanner closer than 3 inches to this area.
You can track the movement of people at stations along their path if they submit to a scanning procedure, but currently people are not tracked without their knowledge using RFID chips.

No, too short a range for people tracking. However, there is a case where a computer user had them inplanted in his hands and added an RFID reader to his keyboard. No need for passwords for that guy. A true nerd among nerds.

How is any rfid going to send a signal more than a foot?
It's going to be the same as you vet. Kind of worthless unless everyone had a scanner they make you walk by :)

That's not what those chips are for, nor do I believe they are capable of doing that. Try reading popular science to get a better understanding.

Here's one experiment where it was used to point to medical records
