What You’ll Learn About QR Codes

QR codes are widely used for marketing, payments, WiFi sharing, contact details, and digital access. In this learning section, we explain how QR codes work, the different types of QR codes, when to use each one, and how to create secure, scannable QR codes for real-world use.

What Are QR Codes and How Do They Work?

A QR code (Quick Response code) is a two-dimensional barcode that stores information such as URLs, text, contact details, WiFi credentials, or payment links. When scanned using a smartphone camera or QR scanner app, the encoded data is instantly decoded and displayed to the user.

Unlike traditional barcodes, QR codes can store significantly more data and can be scanned from any orientation. This makes them ideal for marketing, contactless access, digital menus, product tracking, and authentication use cases.

Modern QR codes also include error correction, which allows them to remain scannable even if partially damaged or customized with colors and logos.
