The fingerprint scanner on Apple's new
Company testers have discovered that the Touch ID sensor will not always respond to fingertips coated in sweat, lotion, or other liquids, an Apple spokesperson told The Wall Street Journal.
Besides fluids, the scanner also doesn't seem to like fingertips with scars. However, the company spokesperson told the Journal that this issue is easily solvable by using another finger on the scanner.
Apple's Touch ID sensor technology is something completely new for smartphone users. The scanner is capacitive, thin, and can scan in 360 degrees. This means the sensor in a certain manner in relation to a user's finger. It also can learn multiple fingers, so it's not limited to just a thumbprint. The technology is said to be superior to laptop fingerprint sensors that make users repeatedly swipe the scanner.
In adding a fingerprint sensor to the iPhone, Apple has begun to. The scanner will presumably act as a first line of defense against would-be thieves and hackers.
Users' fingerprint data will be encrypted and stored on the device's processor -- it will not be backed up to iCloud. According to the Journal, this type of storage means that it should be near impossible for a thief to reverse-engineer someone's fingerprint.
