At Samsung's Unpacked 2016 event, the company revealed that its Galaxy Note 7 will have a futuristic new way to sign in: an iris scanner. It'll do much more than just unlock your phone, though. The Korean company also revealed Samsung Pass, a new security system that will let you access banking and other chores using your eyeballs. Samsung says that it's working with Bank of America, Citibank, US Bank and other firms on the new tech.
