QR code reader

A QR code reader is a software application or mobile app that can scan and interpret QR (Quick Response) codes. These readers use the camera on a smartphone or other devices to capture the QR code image, which is then decoded to reveal the embedded information, such as a URL, text, or contact information. QR code readers are widely used for various purposes, including accessing website links, making payments, storing digital tickets, and sharing information quickly and conveniently.
