Touch ID might have been better in concept than as a practical security measure, but as with any template for future designs, Apple's fingerprint scanner is just the beginning of the company's exploration of biometrics. According to a recent patent, Apple wants to enable a wider range of functionality using your fingers, your eyes and even your voice in the future. The patent suggests that the owner of a device could store any user's biometric data within the device and then restrict or allow access to certain features depending on the user's identification.
