3D Printed RFID Ring

Like many of us, Benjamin Blundell is a bit tired of hearing about wearable technology when it seems that many of the examples just aren't very practical or useful. He decided to do something about that. He created this fantastic example of what wearable technology should be -- aesthetic and functional. Blundell says on his blog that RFID is quite prevalent in London, where he lives, so he carries a card with a passive RFID chip in it. This card grants him access to his local hackerspace and has some other common uses around the city. He set out with the goal of adding the RFID chip to his wedding ring.
