Ah the geek in me will soon be satisfied when my new toy arrives. I ordered an NFC Ring a little while back, and although it really isn’t necessary, I’m really excited by this!

Basically it’s a ring with NFC built in. Store your contact details, passwords and whatever else you feel like. Kind of goofy, but novel, with a few real world uses. Can’t wait for mine to arrive!
