How do QR codes work?

A QR code is a two-dimensional matrix barcode that encodes data using a pattern of black and white squares. It contains four types of functional areas: finder patterns (the three square corner markers that help scanners identify and orient the code), timing patterns (alternating lines that define the module grid), alignment patterns (in larger codes, for correcting perspective distortion), and the data region (the actual encoded information). Crucially, QR codes include error correction data — at Error Correction Level H (highest), up to 30% of the code can be damaged or obscured while still remaining scannable. This is why logos can be placed in the centre of QR codes without breaking them.

QR code best practices for print and marketing

For reliable scanning: minimum printed size should be 2.5 cm × 2.5 cm; ensure high contrast between QR code and background (black on white is ideal, avoid very dark backgrounds); use Error Correction Level Q or H if you plan to add a logo; always test-scan before printing at scale. Common use cases: restaurant menus (reduced physical touchpoints post-COVID), business cards (encode LinkedIn profile URL), packaging (product information, recycling instructions), event tickets, Wi-Fi login codes, and payment QR codes.
