QR Code

The QR (Quick Response) Code is a two-dimensional matrix barcode that stores up to around 3,000 bytes — URLs, text, Wi-Fi credentials, contact cards and more — far beyond what a 1D barcode holds.

How it works

Data sits in a grid of modules with three large finder squares that let a camera read it from any angle, and built-in Reed–Solomon error correction (four selectable levels) keeps it scannable even when partly damaged or covered by a logo.

Where it's used

Found across marketing and daily life: product packaging, restaurant menus, mobile payments, event and transport tickets, and print-to-web campaigns.
