QR Code Scanner: The Ultimate Guide
QR code scanners have seen widespread adoption in India, driven by the country’s rapid digital transformation. From payments to health check-ins, QR codes are becoming an integral part of everyday life in India. This guide provides an in-depth look at QR code scanners in India, their applications, benefits, popular apps, and tips for effective use.
What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can store a variety of data types, including URLs, contact information, and more. Unlike traditional barcodes, QR codes can hold a significantly larger amount of information and can be scanned from any direction, making them highly versatile.
How Does a QR Code Scanner Work?
A QR code scanner is a software application that uses the camera of a smartphone or tablet to read and decode the information embedded in a QR code. The scanner interprets the pattern of black squares and white spaces to extract the data encoded in the QR code, which can then be displayed or processed by the device.
