The gala ring has NFC chips embedded on either side of the ring. One NFC chip is a read only string of letters and numbers, while the other is programmable. The read only portion of the ring is meant to be used as your unique unlock password for any NFC enabled devices. The opposite side allows you to put any information, but was designed with the purpose of holding your business card information. Once configured the Gala Ring should unlock your device automatically when you grasp your phone, and when you touch the back of your hand to a device, it will deliver your contact info to another device.
