How Does iPhone XS Face ID vs Samsung Note 9 Intelligent Scan. Work?

The iPhone XS uses Face ID and the Samsung Note 9 uses Intelligent Scan to know who is holding the phone, like a secret handshake only you can do.

Imagine your face is like a fingerprint, but instead of touching something, you look at it. The iPhone XS has a special camera that takes many tiny pictures of your face, kind of like when you draw a portrait with lots of little dots. It makes a map of your face, and when you look at the phone, it checks if your face matches the map.

The Samsung Note 9 uses something called an iris scan, which is like looking into your eye, not just your whole face. It takes a picture of your eye’s color pattern and compares it to one it already knows. It's like when you match up puzzle pieces: if they fit, the phone unlocks.

Both are smart ways for phones to know who their owner is, one uses your whole face, and the other uses just your eye!
