Tarun Wadhwa of Forbes prefers science fiction over the empirical observation that biometrics works best as a convenience rather than as a security feature, and predicts:

»In fact, it is an almost certainty that within the next few years, three biometric options will become standard features in every new phone: a fingerprint scanner built into the screen, facial recognition powered by high-definition cameras, and voice recognition based off a large collection of your vocal samples.«

Hey may actually be right. Convenience is more important on a mobile device than protection against the rare problem of physical-access attacks. First, however, biometric authentication needs to become as quick, reliable, and easy to manage as the PIN authentication it is supposed to replace.
