What Is a QR Code?
A QR code is a two-dimensional barcode that stores information in a square pattern of pixels. Most QR codes are used to open a website, but they can also store text, contact details, WiFi credentials, app links, and more.
How QR Codes Work
When someone scans a QR code with a smartphone camera, the device reads the pattern and converts it into usable information. In most business use cases, that means opening a landing page instantly without asking the user to type a long URL.
Why QR Codes Matter
QR codes remove friction. They turn posters, packaging, menus, flyers, business cards, and signs into clickable physical touchpoints. That is why they are popular in marketing, hospitality, retail, events, and support workflows.
Common Uses
- Website links
- Product packaging
- Restaurant menus
- App download pages
- Event schedules
- Contact sharing
Final Tip
A QR code by itself is not enough. The scan destination should be mobile-friendly, fast, and clearly connected to the promise near the code.
