QR code have become an essential tool for modern connectivity and information sharing. These black-and-white square patterns store data in a compact, scannable format. From businesses to personal use, QR codes offer convenience, speed, and accessibility. Let’s explore their functionality, history, and diverse applications.

What Is a QR Code?

A QR code, short for “Quick Response Code,” is a two-dimensional barcode. It stores information like text, URLs, or other data. Scanning it with a smartphone or dedicated reader reveals the stored content instantly.

Invented in 1994 by Denso Wave, QR codes initially served industrial purposes. Over time, their use expanded to marketing, payments, and everyday tasks. They surpass traditional barcodes in efficiency by holding more data.

How Does a QR Code Work?

QR codes use black squares on a white grid to encode data. Devices with cameras, like smartphones, decode this data using QR scanning software. This process takes seconds, making QR codes a fast way to share information.

The encoded data could be a website URL, product details, or payment information. QR codes allow direct access to information without typing or manual searches.
