I volunteered at a rescue and I am a big promoter of microchips. I did it on many dogs and cats. ALL of our shelter animals were microchipped before going to the new owner, and the animal was registered in their name. Also, the rescue offered microchipping services to the public for $15. It is such an easy procedure. It was actually the first "procedure" I did as a vet tech. There are very rarely any side effects. occasionally there is a bit of bleeding, but that's about it. The chip itself is about the size of a grain of rice and the needle looks a little big and scary, but it was so quick that the animals wouldn't know what hit them!
I've never heard of any chips with GPS features on them. They mostly just contain a code that is picked up by a scanner when it is run over the neck of the dog. Then that code is entered into the computer and the owner's info can be pulled up. We scanned every cat and dog that came into the shelter. Unfortunately, few people microchipped and so we rarely found any in the animals. Also, the $15 was a one time fee. Vets usually charge a bit more, but I think even for $40 or $60 it is worth it.
Microchips in animals and microchips in humans are two extremely different things. You are responsible for your animal's safety and a microchip is extremely useful in this. It wouldn't be infringing on any animal right that I am aware of. As long as you keep the info current, I can't think of any negatives in having a chip.
