It has already been rumored that the Samsung will finally do away with the home button on the Galaxy S 5, and the Korea Herald is confirming it. They are also reporting the GS5 will sport a bezel-free display that supports fingerprint scanning.
However, contrary to an earlier report, the scanner will not utilize the entire display. It will only be available at the bottom left and right sides of the display. This still sounds like the earlier report in that it will be a swipe scanner. My guess is that the phone will read the fingerprint during the swipe to unlock movement. However it’s implemented, I just hope it works well.
Eventually, the entire display will be utilized, but that technology isn’t ready for mass production yet.
