Not to be outdone by Apple’s Touch ID, Samsung is using it eye and face detection experience and taking it to the next step.
This would mean it would scan your eye balls to unlock your phone.
Hmmm not so sure what I think about that one. What’s your view on the idea?

Mmmmm… I wonder if it will come with “Bleary Mode” for the millions of users who would otherwise not be able to switch on their phone the first thing in the morning!

Retina scanning used at airports, not sure how reliable it is! Face detection would be relatively easy to implement and I am sure could be very accurate.
