What Is a QR Code?

A QR Code (Quick Response Code) is a two-dimensional matrix barcode capable of encoding URLs, contact cards, text, and rich data. Unlike linear 1D barcodes scanned by laser checkout devices, QR codes are captured by camera sensors on smartphones.

Real example

A product box displays a QR code reading 'Scan for 20% off your next order.' When scanned by a smartphone camera, it opens a web browser to a landing page.

How a QR Code is used in e-commerce

  • Printed on product packaging to link customers to digital instruction manuals, warranty activation forms, or promotional videos.
  • Used in digital menus, event ticketing, and direct-to-consumer loyalty campaigns.
