What is that square on my snack bag?
It is a QR code.
A phone can read this small picture.
I open my camera and scan it.
At first, nothing happens.
Then, a page opens.
It shows more about the snack.
My bag has a simple game.
I tap the screen.
I find a little star.
That is fun!
But I check the web address too.
If it looks strange, I stop.
A tiny square can open a big door.
Scan with care. Enjoy the surprise.
