We really don't have a clue what Apple is planning for its next iPhone just yet. If history repeats itself, and it often does, then Apple won't tweak the industrial design of the iPhone 6 and iPhone 6 Plus too much, but will offer some new hardware features that improve the experience for end-users. One new piece of technology could be an improved Touch ID sensor, according to one analyst.

KGI analyst Ming-Chi Kuo, known for reporting on Apple's supply chain, says he has found evidence that Apple is working to add a new and improved Touch ID sensor into next year's iPhones. The new Touch ID sensor will "offer a better and safer Apple Pay user experience by reducing reading errors," he said in a recent note, according to AppleInsider. Kuo added that rumors of a full touch-screen Touch ID experience aren't going to come to fruition just yet.

"Though Apple has filed patents for the integration of Touch ID and touch panel, this isn't likely to bear fruit near term as complex algorithms and sapphire cover lens are also required," Kuo explained. "We therefore don't see any impact on supply chain momentum." Touch ID is already pretty accurate but we can get on board with improvements, too.
