QR Code Accessibility: Making Your Codes Work for Everyone

Why Accessibility Matters

Over 1 billion people worldwide have disabilities. A QR code placed at standing eye level excludes a wheelchair user; a landing page without alt text excludes a screen-reader user; a low-contrast "designer" code excludes anyone with low vision. Fixing these is rarely expensive, and it's often legally required.

Three fixes you can ship today

Print the destination URL under every public code, check your placement heights against the 90-120cm range, and run your landing page through WAVE once. Those three changes cost almost nothing, cover the most common barriers, and give you a working baseline while you plan the fuller WCAG audit.
