WHY QR CODE IS USED

What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that can be scanned using a smartphone or other device with a camera. It was invented in 1994 by Masahiro Hara, an engineer for the Japanese automotive company Denso Wave. QR codes are similar to barcodes, but they can store more information and are easier to scan.

How Do QR Codes Work?

QR codes use tiny black and white squares, known as modules, arranged in a grid to represent data. The size of the QR code determines how much data it can store. A small QR code can hold a few characters, while a larger QR code can hold a website address, a phone number, or even a document.

When a QR code is scanned, the squares are detected by the camera and translated into data, allowing the device to take the user to a specific website, open a file, or perform another action.

QR codes are used in a variety of applications, including:

1. Marketing: QR codes are used to promote products and services. They can be printed on business cards, posters, and product packaging. By scanning the QR code, customers can access more information about the product or service, such as its features, reviews, or pricing.
