QR Code Reader

A QR Code Reader is an application or device that scans Quick Response (QR) codes—square barcodes containing information. When scanned with a smartphone or a QR reader, the code quickly provides access to various types of content, such as website links, contact details, or text. The technology uses a camera to capture the code, which is then analyzed to decode the information. QR codes are commonly used in advertising, ticketing, and payments, making it easier for users to access information quickly and efficiently without needing to type it manually.
