Data exchange rings
Imagine that all you need is to shake hands with someone to get all of their personal info; well this could be true soon if the concept design gets the thumbs up.
You get a card and ring, the data on the card is transferred onto ring and when you shake hands with another ring holder the data is exchanged.
No need to worry about power either the rings are powered by the heat from your body.
