What is a QR code and how does it work?
A QR code (Quick Response code) is a two-dimensional matrix barcode composed of black and white squares arranged in a square grid. It stores various types of information, including URLs, contact details, Wi-Fi credentials, and more. When scanned with a smartphone or dedicated QR code scanner, the device's camera captures the pattern of squares, and decoding algorithms interpret the pattern to extract the embedded data.
This process involves several components: the position markers (large squares at three corners for orientation), alignment patterns (smaller squares for skew correction), timing patterns (horizontal and vertical lines to determine module size), format information (error correction level and mask pattern), and the data region (actual encoded information). Error correction techniques, such as Reed–Solomon codes, enable the QR code to be read accurately even if partially damaged or obscured.
Once decoded, the device automatically performs actions like opening a website, saving contact info, connecting to Wi-Fi, or processing a payment. This seamless integration between physical and digital realms makes QR codes versatile tools across industries including marketing, healthcare, retail, and logistics.

Examples:
Dynamic QR Codes
Generate a short URL redirecting to your content. You can edit or update the destination after printing, support scan analytics (location, date, device, time), and retarget users online. They suit ongoing campaigns, inventory management, or content updates without reprinting.
Examples:
Key Differences
Summary
Use static QR codes for fixed, one-time information. Choose dynamic QR codes for campaigns requiring flexibility, tracking, and updates. To optimize your campaigns, see our social media content calendar.
