Apple Touch ID Moving Aside

According to Apple Insider, the company plans to replace their existing Touch ID system with optical fingerprint readers - apparently to make accommodation for new "full face" hardware designs.
A capacitive solution, Touch ID sends a small electrical charge through a user's finger by way of a stainless steel metal ring. While the fingerprint sensing module is an "under glass" design, the ring must be accessible to the user at all times, making the solution unsuitable for inclusion in devices with full-face screens.

KGI analyst Ming-Chi] Kuo predicts Apple will turn to optical type fingerprint sensing technology capable of accepting readings through OLED panels without need for capacitive charge components.
