A QR code is like a magic square that can hold lots of information. When you scan it with your phone, it shows you a website, a message, or even a video, all in just one quick snap. It’s super fast and doesn’t need any typing, which makes it perfect for people who want to get information quickly.
Examples
- A restaurant menu has a QR code you scan to see the full menu on your phone.
- A poster with a QR code lets you watch a video just by scanning it with your phone camera.
- Your friend sends you a message via a QR code, and all you need to do is scan it to read it.
