The guide
Scanning a QR code in a physical environment has become second nature to consumers. From restaurant menus to conference badges, QR codes bridge the physical and digital worlds.
1. High Contrast is Non-Negotiable: Always use dark foreground modules on a light background. Inverted QR codes (white dots on black paper) frequently fail in direct sunlight or dim restaurant lighting.
2. Choose the Right Error Correction Level: If you are printing on t-shirts, packaging, or outdoor signage where weathering or wrinkles may occur, select Level H (30% error recovery). For clean digital screens, Level M (15%) is optimal.
3. Maintain the Quiet Zone: Every QR code requires a blank border (quiet zone) around its edges. Never crowd text or design elements flush against the QR grid.
