I mentioned the same thing about a year ago. I believe the chips have been available since 99. I don't understand why the US military and the NGOs that work in dangerous areas don't utilize this life saving device? I believe that there are two types of devices. One is a low cost passive id chip. Which is what can be used to identify lost pets and perhaphs lost children. It requires that you take the lost pet/person to the scanner device so that it can "read" the embedded chip's ID. The embedded chip does not require batteries, and works like the the current set of scanner badges that many employers use. The scanner device actually transmitts enough energy to the the "chip" or badge (which must be placed within inches of the scanner) so that the the chip or "badge" can retransmit a short digital ID number. This ID number is then looked up in a database. Such a device will obviously not work with hostage takers and terrorists. The other type of device is a GPS transceiver and transmitter. It uses a GPS tranceiver to determine the exact location of the device. These are used in automobile navigation systems and other GPS devices. There typicall are used to tell a GPS user of his current location. However since you want to locate this device remotely you have a more difficult problem. To locate this device remotely, the device also needs to retransmit the GPS information on a radio frequency so that you can retrieve this information remotely. This second type of device is far to large to be "embedded" in a human or a pet and requires batteries for both the transmitter and GPS reciever. Here is a web site that has a picture of such a device (which cost $999.00) spytechs.com Note that the transmitter include in this device only works for a line-of-sight distance of 250 feet. Your application would require a much stronger transmitter, once that would work from 20 feet under ground.
