A QR code reader is a software application or device that utilizes the camera or scanner to interpret and decode QR (Quick Response) codes. QR codes are two-dimensional barcodes that store information such as website URLs, text, contact details, or other data. QR code readers extract the encoded information from the QR code and display it as text, a link, or as contact information, depending on the type of data stored within the code. These readers are commonly used in various applications, including mobile devices, digital payment systems, marketing campaigns, and inventory management, enabling users to access and interpret data conveniently and efficiently.
