NFC contact-exchanging jewellery

Hi all! We at Siignia have launched our first Kickstarter campaign for our flagship product, the iiD.

We've created NFC-embedded jewellery that makes exchanging contact details easier, faster and smarter. They're made from Rhodium-plated silver, and can be worn in many different ways; eg as a necklace, wrist strap, keychain or tie clip. Check out our project by searching 'iiD' on Kickstarter!

What do you think about NFC? How about using it in jewellery?
