Apple's 'iPhone 5S' to boast fingerprint sensor embedded in convex sapphire home button

By using a convex home button instead of the familiar concave design, Apple will be able to make room for the much rumored fingerprint sensor without losing precious internal space, according to well-informed KGI analyst Ming-Chi Kuo.

In a research note obtained by AppleInsider, Kuo says Apple is using sapphire because of its resilience to scratches, which will thus protect the fingerprint sensor embedded within.

AuthenTec, the biometric security firm Apple purchased in 2012, uses leading-edge capacitive and RF technologies in its biometric chips, a method that images fingerprints differently than existing optics-based systems. Kuo believes the tech is superior as the sensor is not subject to misreadings due to the build up of detritus or dust.

Further, the analyst sees Apple's current one-button iPhone design as being an optimal fit for a fingerprint reader. With a single home button, consumers are less likely to be confused as to where to place their finger for scanning.
