In today’s digital age, QR codes have become an essential tool for businesses, marketers, and individuals alike. These square barcodes can store a vast amount of information, from website URLs and contact details to coupons and payment information. However, many people are still unsure about how to view a QR code on their phone. In this article, we will take you through a step-by-step guide on how to scan and view QR codes on your mobile device.
What is a QR Code?
Before we dive into the process of viewing QR codes, let’s first understand what they are. A QR code, short for Quick Response code, is a type of matrix barcode that stores information, such as text, URLs, or other data, in a square grid of black and white modules. QR codes were invented in the 1990s by Masahiro Hara, an engineer at Denso Wave, a Japanese automotive components manufacturer. Initially, QR codes were used to track parts in manufacturing, but they have since become widely used in various industries, including marketing, advertising, and finance.
How Do QR Codes Work?
QR codes work by storing information in a series of 0s and 1s, which are represented by the black and white modules in the grid. When a smartphone camera scans the QR code, it detects the pattern of 0s and 1s and decodes the information stored in the code. The decoded information is then displayed on the phone’s screen, allowing the user to access the stored data.
