A QR Code (Quick Response Code) is a two-dimensional barcode that can store information such as URLs, text, or contact details. It consists of black squares arranged on a white grid, which can be scanned using a smartphone camera or a dedicated QR code reader. This technology allows users to quickly access information without typing it manually. QR Codes are widely used in various industries, including marketing, retail, and event management. They can be found on product packaging, advertisements, and tickets, making it easy for consumers to engage with brands or access services by simply scanning the code with their devices.
