QR codes are like a secret message that you can scan with your phone, just like how a treasure map leads to hidden gold. Imagine a little square with black and white blocks: when you point your phone at it, the phone reads the pattern and shows you a website, a video, or even a fun game! It’s super fast and doesn’t need any typing, just a quick scan, and poof! You're there.
Examples
- A QR code on a bus shows you where the next stop is.
- You scan a QR code at a restaurant to see their menu.
- Your friend sends you a QR code with a secret message.
