It's different from the tagging you described. The range is very limited - tag reader has to scan the animal touching the fur. Nothing happens on pet cemetery. The news is that it's even smaller now and doesn't require external cap, not that it will be active RFID.

I think the use in wild life vs pets would be something like 1:100 . The tag is encapsulated in tiny glass container just like current ID tags - the size of rice grain. Given its size it would be embedded just like it is done now. If it gets swallowed by predator it would come out within 2-3 days. Current tags are passive and don't transmit - they are read by tag reader at the distance of a 2-3 inches. It sounds like new tag doesn't have antenna so it would not transmit as well. So it's the same 2-3 inches reading range. Search on interwebs for "microchip animal id" to see how it works now.

My knowledge is limited to the information in the article: Without an intentional "kill" mechanism in the packaging or failure of the package integrity ... which disrupts the circuitry. The tag could work indefinitely... creating the rf-tag equivalent of "space junk" in the worst case. The good thing is the tags are passive and have to be within a read-range. Why is embedding in wild animals a problem? Fixed low tech tags are placed on wild animals routinely. That issue is best solved by an animal science professional. South Dakota State University electrical engineering department was tagging pheasants for rf tracking purposes back in the late '60s. If I'm not mistaken that was about a 1/8 mile read range for an active tag. When the pheasant was consumed by a predator, the transmitter failed or was left transmitting from a fixed location for recovery. What is the read range for the passive application? What happens in a pet cemetery?

Animal ID is a good application for RFID technology. Only problem would be successfully embedding such device into wild animals skin. Other problem would be that in case of animals falling prey to their predators,what happens to the their tag? The tags may get swallowed by the predators! Would the be still communicating ?
