A QR code (Quick Response code) is a two-dimensional barcode that stores data — URLs, text, WiFi credentials, contact info (vCard), payment details (UPI), and more. When scanned with a smartphone camera or QR reader app, it instantly opens the encoded information. QREndlessPro supports 1,421+ QR code types across 38 categories.

What Is a QR Code?

A short, practical guide — what QR codes are, how they work, and where they are used today.

A QR code (Quick Response code) is a square barcode that stores information. When you scan it with your phone camera, it opens a website, connects to WiFi, makes a payment, or shows contact details — instantly.

QR codes were invented in 1994 by a Japanese company called Denso Wave. They were originally used to track car parts in factories. Today, you see QR codes everywhere — on restaurant menus, business cards, product packaging, event tickets, and payment apps.

Static QR Codes

The data inside a static QR code is fixed. Once you create it, the content cannot be changed. Static QR codes are best for WiFi passwords, contact details, and permanent links.

How QR Codes Work

A QR code stores data as black and white squares in a grid pattern. Your phone camera reads these squares and decodes the information. Error correction lets QR codes work even when partially damaged.
