Let’s talk about rings. After the Bitcoin engagement ring here we are talking about another one, less romantic but very functional: the NFC ring.

Besides being useful for wearable payment, NFC technology has been applied to unlock our smartphone without using password, or to open the door at home: in the first case it is sufficient to approach the back of the smartphone (on which you installed a dedicated app) to theNFC ring,while in the second case you will approach the ring to the lock of the door.
The NFC ring will be avaliable on the market next September at a cost of about $ 20 … consider that on Kickstarter it has collected three times the asking amount! Not bad, right?
