A QR code decoder is a tool or software that can interpret the information stored in a QR (Quick Response) code, which is a type of matrix barcode commonly used to store data in a pattern of black squares arranged on a white background. A decoder works by scanning the QR code, generally using a camera on a smartphone or a specialized QR code reader, and then processing the pattern to extract the information stored in it, which can be a URL, text, contact information, or other data. It converts the graphical information into a human-readable format, facilitating quick and efficient data retrieval. View more: Codexcoach
