Want a new way to exchange business cards without needing to actually carry them around? A company has developed a new way to "carry" your digital business card, which contains customizable personal information, inside of a normal-sized ring. The best part is that to exchange your digital business card with another person, all you do is shake their hand.
Shaking hands will automatically tranfer info between rings.

Each ring syncs with a credit card-sized digital business card, and it will display a database of all of the people that you've exchanged information with - including personal info, phone numbers, address, date that you met this person, and all of this information is customizable. When two people wearing the special "smart" rings shake each other's hands, this information is transferred between the two rings. You then sync the ring with the digital business card to view this information on the card itself.

Obviously, in order for this gadget to work, you need to supply some sort of power source to the ring. The makers of this "smart" ring have come up with an innovative and smart solution - the rings are powered by your body heat. No batteries required.
Place the ring at the designated spot on the digital business card to view database of people that you've met.

There's no doubt that little gadget is cool and most business travelers would probably agree, but there is an obvious drawback to this new technology. The whole system will not work unless both people are wearing the rings. So until the idea of "smart" rings which transfer digital information by handshake becomes widespread in the business world, these digital business cards are pretty much worthless. I'd love to see this technology take off though!
