iPhone 5s Touch ID won’t store fingerprint images

Apple’s new Touch ID system in its upcoming iPhone 5s won’t store users’ fingerprint images on the device, an Apple spokesman said. Touch ID will store encrypted “fingerprint data” in the iPhone processor, according to the Wall Street Journal. At this point, third-party applications will not be allowed to use the scanner. Touch ID users will also be required to set a passcode as a backup. Although the sensor is said to perform better than laptop fingerprint scanners, Apple noted Touch ID may have issues reading fingertips covered in sweat, lotion or liquids. The system might also struggle with reading scarred fingertips.
