What is behind that little square?
Mina opens a bag of cookies. She sees a QR code. It is a small square. Her phone can read it.
So, Mina scans the code. She thinks, “Is it a game?”
But a web page opens. It shows what is in the cookies. It also shows which bin to use. QR codes can share product information online. (gs1.org)
The bag has little space. The web page has more.
That small square is like a door. Next time, open the door and look.
