Designer Hideaki Matsui's new concept works on the principle that shaking hands is an international customary greeting action.

The "Information Ring" is designed to exchange basic information, as would normally appear on a business card, with new people the first time you shake hands with them.

Where it gets interesting though is that the more people meet, the more information is transferred from ring to ring.

We wonder how many times you'd have to have a face to face before embarrassing school pics, your "amusing" drunk party trick and your partner's pet name for you would be beamed across.
