The revolution lies in passing of information swiftly and efficiently, and this product is designed to simplify exchange of basic information with as simple an act as shaking hands. When people first meet and shake hands, the rings on the fingers get close enough to operate and store the info as wearing parties, shake hands. The included card can display the information stored in the ring, and the intended power source is to be provided by the temperature of the wearer. Self sustaining and high tech.
