QR codes are like puzzles made of squares. When you scan them with a phone, it reads the pattern and figures out what message or link is inside. It's like a secret code that your phone can understand!
Examples
- A restaurant puts a QR code on its menu so you can scan it with your phone and instantly get the online version of the menu.
- A bus stop has a QR code that links to a map showing the best routes from there.
