Quick Response (QR) is a type of two-dimensional barcode that stores information in a pattern of black squares arranged on a white square grid. In the retail context, QR codes find widespread use for various applications, including product labeling, marketing, and facilitating quick access to digital information. Consumers can use smartphones or dedicated QR code readers to scan these codes, enabling the rapid retrieval of encoded information. Retailers leverage QR codes to provide product details, enable mobile payments, offer discounts, and create interactive marketing campaigns. QR technology enhances the efficiency and interactivity of the retail experience by seamlessly connecting physical products with digital content and services.
