What Are QR Codes and How Do They Work?

A QR code (Quick Response code) is a special type of barcode that can hold more information than a standard one. You can store links, text, contact info, or other data — making it easy to connect the physical and digital worlds.

How QR Codes Work

When you scan a QR code using your phone’s camera, it reads the black-and-white pattern and performs an action — like opening a website, showing a message, or connecting to Wi-Fi.

Common Uses of QR Codes

• Open websites or app downloads quickly
• Display restaurant menus or event info
• Enable fast, contactless payments
• Share Wi-Fi passwords or contact details
