What Is a QR Code?

A QR code (abbreviated from Quick Response Code) is a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL or other data.

QR codes are used to store and share small amounts of digital information such as website URLs, contact details, product prices and more. They are widely used by businesses to promote their products and services, as well as by individuals who want to quickly share content with others without having to type out long web addresses or phone numbers. QR codes can also be scanned using smartphones equipped with camera technology that reads the code’s contents automatically when it is pointed at it.
