QR code scanning is the process of using a camera-equipped device, like a smartphone or tablet, to read a QR code. A QR code (Quick Response code) is a two-dimensional barcode that can store information such as URLs, text, or contact details. When scanned, the device decodes the information and often directs the user to a specific website or application. To scan a QR code, users typically open a camera app or a dedicated scanning app. They then point the camera at the QR code until it is recognized. Once scanned, the device displays the information or prompts the user to take action, such as visiting a website or saving contact information.
