Concept Definition

QR (Quick Response) codes are two-dimensional barcodes that can store information in the form of text, URLs, email addresses, phone numbers, or even videos. They were originally designed for use in manufacturing, quality control, and inventory management. However, their popularity has grown exponentially with the rise of mobile devices, making them an essential tool for businesses, marketers, and individuals alike.

A QR code consists of a square grid of black and white modules (small squares) arranged in a specific pattern. When scanned using a smartphone or tablet camera, the QR code decoder reads the data stored within and displays it on the screen. In this article, we’ll focus on scanning QR codes using your laptop.
