Apple presented a facial recognition system as a way for users to unlock its next iPhone during its latest launch event on Tuesday, but such security solutions may not prove popular with consumers.

Face ID uses advanced 3-D depth perception to scan the user's face. This process reportedly captures more data points and works faster than Apple's Touch ID system, which scans fingerprints.
