Computing devices with fingerprint scanners aren't new. IBM introduced a laptop with an integrated fingerprint reader way back in 2004. And the Motorola Atrix 4G smartphone had one in 2011. Well, the iPhone 5S is expected to integrate a fingerprint sensor with the home button, but why? Users aren't exactly clamoring for the feature, which could be used in lieu of a passcode to unlock the phone, access digital wallet capabilities (for online shopping, for example), or perform other tasks that only Apple knows about for now. Fingerprint scanning is an intriguing idea, but will it be faster and easier than passwords for the average iPhone user?
