Companies have tried and implemented it in really niche devices, but the tech has happily avoided the mainstream. It is about to change, as seemingly true information from the iOS 7 beta 4 build points to a "Biometric Kit UI" directory that confirms that Apple is interested in implement high grade security, right on your new iPhone's home button. The leak comes from a developer how has had the opportunity to see the leaked folder on the latest iOS 7 beta build with strings like - "..touching the home button with their thumb", "A fingerprint that changes colour during the setup process" and "Recognition is %@ complete".
