  Apple’s face recognition system relies on

  1. infrared light being blasted on your face
  2. infrared camera creates a map of your face based on the 30k dots blasted onto your face and stores it
  3. when you try to log in again your iPhone compares your face by repeating step 1 and 2 (but not storing the map this time) and comparing it to the map created in step 2.
  4. if the black box “machine learning” program thinks your face is similar to the map, it lets you in.

  The IR blaster and camera makes Apple’s system more accurate and secure (requires 3D face) than just taking a photo of your face (2D), but it does take up more room on the notch.

    I see, well I’ll gladly keep my fingerprint sensor over that unnecessary mess.

      I personally like the system, and it works 99% of the time. But I can see where you are coming from.

      What do you have against it? I was hesitant at first, but it works really well and quite happy with it

        Had an lg v30 with back fingerpad, tried to switch to an iPhone x, no go.

        Back fingerpads are amazing, my fold z 3 has a side pad and it’s fine too, but the in-screen ones blow almost as bad as face readers.

    Face ID also works as well in darkness as in daylight.

    when you try to log in again your iPhone compares your face by repeating step 1 and 2 (but not storing the map this time) and comparing it to the map created in step 2.

    It stores the map every time. That way if, for example, you grow a beard it will learn.

  How do people know at a glance which apps have unread notifications?

  Basically, you don’t. At least, not in the same way as an Android phone. Notifications are visible on your lock screen or by swiping down from the top to the left of the notch. I’m an Android to iPhone switcher and app notifications in the top bar is the thing that I miss the most.
