Today, you can get a scanner embedded into the rear panel, one nestled on the bottom front bezel, and as of fairly recently — on the side, where your power key would usually go. All of these placements offer distinct advantages and disadvantages, and it's madness trying to objectively rank them, but that doesn't mean people won't have preferences. For one, we all use marginally (or vastly) differing grips with our devices, and that changes a whole lot.
So if you were to pick the placement of the fingerprint scanner, would you go front, side, or rear? Vote now to settle the debate!
