QR Code
A QR (Quick Response) code is a type of matrix barcode that stores information as a series of pixels in a square-shaped grid. QR codes can be scanned using a smartphone camera or a QR code reader, leading users to a website, text, image, or other digital content. They are commonly used in marketing, advertising, and events to quickly direct people to online resources, provide product details, or facilitate transactions. QR codes offer a convenient and interactive way to connect physical and digital experiences, making information easily accessible with just a scan.
