Imagine your fingerprint is like a secret code only you know. A fingerprint scanner reads that code when you touch it, and if it matches the one stored on your phone, your phone unlocks. It's like having a special key hidden inside your finger.
Examples
- Your phone unlocks the moment you touch it because your fingerprint is like a secret code.
- A fingerprint scanner reads tiny ridges and valleys on your finger to know it's you.
- Even if someone steals your phone, they can't unlock it unless they have your fingerprint.
