QR Code Scanner

A QR code scanner is a device or app that reads Quick Response (QR) codes, which are square barcodes filled with patterns. When scanned using a smartphone or dedicated scanner, the QR code quickly directs users to information, websites, or actions, such as entering Wi-Fi passwords or making payments. To scan, simply open the scanner app, point the camera at the QR code, and it will decode it instantly. QR codes are commonly used in marketing, ticketing, and contact sharing, making it easy to access digital content with just a quick scan.
