Matrix codes, often referred to as QR codes, are two-dimensional barcodes that store information in a grid format. They can be scanned using a smartphone or a dedicated scanner, allowing users to quickly access data such as website links, contact information, or product details. The unique pattern of black squares on a white background encodes this information, making it easy to read. These codes are widely used in various industries, including marketing, retail, and logistics. By simply scanning a matrix code, users can engage with digital content or services without needing to type in lengthy URLs or information manually.
