This product is designed to exchange basic information with new people in the first meeting by shaking hands.The most essential part of a nomadic life style is frequent travel. Similarly, nowadays people are traveling more often. In fact, it became easier to move from one place to another. Increasing opportunities to travel indicates increasing opportunities of meeting new people. When people first meet and shake hands, the rings on the fingers get close enough to operate.

The rings exchange their users information and stores them while they are shaking hands. So, the more people they meet, the more information they have. When the users browse through the people they meet, the card displays their basic information that was stored in the ring. The power source is provided from human temperature, so it doesn’t need any plug.
