Real or Not?
Some bad people print fake money to fool stores. Real bills have tricky patterns and special inks that are very hard to copy.
Cashiers sometimes use a little scanner with a camera and AI inside. It checks the patterns. If anything's off, it beeps. Then a person decides what to do.
What makes a real bill hard to fake
- Tiny secret patterns only special cameras can see
- Bumpy ink you can feel with your finger
- Numbers that change color when tilted
Key terms in this lesson
The big idea: AI scanners help spot fake bills fast, but a human eye and a good store policy finish the job.
