Instead of fingerprint scanning, the iPhone X will use facial recognition as the main method for authentication. The Face ID technology is fast and accurate for unlocking a device, according to Apple, and will work even in less-than-ideal conditions such as near darkness. The iPhone X thus follows the use of facial recognition for authentication on two of the most business-oriented smartphones on the market -- Samsung's Galaxy S8 and Galaxy Note 8. "Security features are high on business users' list – Face ID is a major enhancement," Goldstein said. "Now Apples adds the features that gave Samsung the edge."
