What if there was a ring model that contained only the private data side of the ring and had a aesthetic design that was consistent around the entire ring? The idea being that it would be used for unlocking or accessing more sensitive data or locks; such as unlocking a safe or something like that. A ring that could be used as a wedding band without drawing any attention to itself could definitely appeal to a lot of people. It ads a whole new market to the rfid ring. I know I would certainly want one.
