How to Use a QR Code

In today's tech-driven world, QR codes have become increasingly ubiquitous. These square barcodes, often seen on advertisements, product packaging, and even business cards, offer a quick and convenient way to access information and services. But how do you actually use a QR code? If you're a newbie to this technology, this comprehensive guide will walk you through everything you need to know.

What is a QR Code?

A QR code (Quick Response code) is a type of two-dimensional barcode that stores information in a series of black and white squares. Unlike traditional barcodes, which can only hold a limited amount of data, QR codes can store much larger amounts of information, including URLs, contact details, text, and even images.
