Touch ID Replacement

Apple is developing advanced biometric security technologies, including facial recognition and optical fingerprint sensing designs, to replace the Touch ID module that was implemented in all iPhones and iPads since the release of the iPhone 5s. Touch ID is a capacitive type fingerprint sensing module based on technology acquired through Apple's purchase of biometric security specialist in 2012 so 5 years ago.  There is a 500 ppi sensor capable of scanning sub dermal layers of skin to obtain a 3D map of a fingerprint. So it basically sends a small electrical charge through  users finger by way of a stainless steel metal ring. It is unclear when Apple might first integrate facial recognition hardware in its expansive product lineup, but optical fingerprint modules are ripe for inclusion in an OLED iPhone rumored to launch later this year. According to recent sources, Apple's first OLED iPhone model will sport a stainless steel "glass sandwich" design and incorporate advanced features like wireless charging. Apple is primed to transition to next-generation 3D Touch tech with the forthcoming handset.
