QR Code technology
A QR code is a type of barcode that stores information visually in a square grid of black and white modules. When scanned with a smartphone or QR code reader, it quickly decodes the embedded data—such as URLs, contact details, or product info—allowing instant access without manual input. QR codes are versatile and widely used for marketing, ticketing, payments, and information sharing because they are easy to generate, scan, and can hold a significant amount of data in a compact form. This technology bridges physical and digital worlds efficiently and securely.
