Keeping tags on it

Intelligent dog tags developed at the Pacific Northwest National Laboratory
in Richland, Washington, can store and broadcast information about a soldier’s
state of health. That means battlefield victims can get better treatment. The
tags, which have a microchip transceiver and antenna, store the ID and any
previous injuries. Soldiers wear the rubber-encased dog tags round their neck as
normal. A paramedic can carry out treatment on an injured soldier and update the
information in the tags at the same time with a wireless palmtop.
