Today Samsung finally announced the launch of their latest smartphone, the Galaxy Note 7, it comes with a range of new features and a brand new design but only one that is really confusing and that is the new iris scanner.

From what we have seen, many people are wondering what this feature does, and why they should be interested in it. Thankfully, we are here to help you with that.

Basically the iris scanner’s main purpose is to add another layer of security to your smartphone, and works similarly to the fingerprint scanner, but of course, it uses your eyes, not your fingerprint. This means that you can be sure that no unauthorised person can use your phone.

To do this, Samsung has built an infrared sensor right into the phone to detect the patterns in the user’s iris. Once pointed at a registered user’s eyes, the phone will be unlocked.

Setting this up will involve lifting the phone up to your eye and waiting for the phone to finish up the capturing of your iris, once finished, you are ready to unlock your phone with your eyes.

However, at the moment, that’s all it can do. That said it is possible that Samsung will expand this to things like protected folders and Samsung Pay.
