Imagine your finger is like a unique puzzle piece. A fingerprint scanner takes a photo of this puzzle, and then it compares it to the ones it already knows. If they match, you get in! It’s like having a secret club where only people with the right puzzle pieces can join.
Examples
- Your finger is like a special key that fits only your lock.
- A scanner takes a photo of your fingerprint just like a camera would.
- The phone compares this new picture to one it already saved.
