The use of QR codes in modern technology serves various purposes, primarily by facilitating quick access to information or services through mobile devices. QR codes can store URLs, contact information, payment details, and promotional content. Users scan the codes with a smartphone camera, which instantly redirects them to the associated content or action. This technology is increasingly employed in marketing, ticketing, and payment systems, enhancing customer engagement and streamlining transactions. As a result, QR codes have become a ubiquitous tool for bridging physical and digital interactions in today’s digital economy.
