This ring may not seem very unique technological, after all it is a ring, even if it has unique little dots encoded into it. These dots represent letters within binary code. This means that you can have a secret message placed within the ring.
It can hold upto 64 characters which means that you can have a decent sized message. Though you can no encode large messages but you can stick with things like “Forever Yours” but there is no fun in that.
This isn’t a product you can purchase just yet, but we can hope that eventually it will be. You can check out more on the ring on creator’s site.
