What is a QR code and how it works
A plain explanation of QR codes, static vs dynamic, and where they are used.
What is a QR code
A QR code is a 2D graphic code a smartphone can read with the camera — a bridge between physical media and digital content.

How it works
The code stores data. Your phone reads the pattern and opens the result — see, aim, open.

Where QR codes appear
Static vs dynamic
Static
Data lives inside the printed code — Wi-Fi, phone, address, fixed links.
Dynamic
Keep the same print, change the destination in your account and track scans.
Why QR codes spread
One scan replaces typing URLs, searching and fixing typos — that simplicity is the main advantage.
