QR Code Readers

QR code readers are devices or apps that scan and interpret QR codes—matrix barcodes that store information like URLs, text, or other data. Using a camera or scanner, they quickly analyze the pattern of black and white squares within the code. Once decoded, the reader translates the pattern into usable information, such as opening a webpage or displaying contact details. These tools enhance efficiency and accuracy in accessing digital content, making information sharing fast and contactless. QR code readers are widely used in retail, marketing, and documentation for seamless data access and exchange.
