What are qr codes?

A QR code is like a picture that tells you where to go or what to do when you look at it with your phone.

Imagine you're playing a game on your phone, and someone shows you a little square with black lines and white spaces. If you point your phone at it, poof, the game changes, or you get directions to the park! That little square is a QR code.

Think of a QR code like a map on a tiny piece of paper. Instead of drawing roads and landmarks, it uses patterns of black and white squares. Your phone can read these patterns, just like your eyes read words.

People use QR codes to make things easier. For example, a restaurant might put one on a table so you can scan it with your phone and see the menu right away, no more waiting for the waiter! It’s like having a shortcut from the real world into your phone.
