QR code accessibility under WCAG (Web Content Accessibility Guidelines) ensures that QR code implementations don't exclude users with disabilities. Accessibility considerations span visual impairment, motor limitations, and cognitive accessibility. WCAG compliance requires sufficient color contrast (minimum 4.5:1 ratio), alternative text describing the QR code's purpose and destination, and non-QR alternatives for accessing the same content. Physical placement must accommodate wheelchair users. URL shortening services generating QR codes should provide accessibility guidance and tools: contrast checking for custom-colored codes, automatic alt-text generation including the destination description, and companion short URL text for users who cannot scan codes. Accessible QR implementations expand audience reach while meeting legal compliance requirements.
