1. What Is a QR Code?
A QR code, short for Quick Response code, is a two-dimensional barcode that can store various types of information such as website URLs, contact information, or product details. QR codes are square-shaped and consist of black modules arranged on a white background, allowing them to be easily scanned by a mobile device.

Scanning QR codes requires a smartphone or a tablet equipped with a QR code scanner app. Once the app is open, you simply point your device’s camera at the QR code. The scanner app will then analyze the code, extract the encoded information, and perform the corresponding action, such as opening a website or displaying contact details.
