Quick Answer

Accessible QR deployment means the linked experience and the surrounding information work for people with disabilities. For meaningful digital graphics, WCAG 2.2 may require 3:1 non-text contrast; printed placements also need scan testing, clear labels, reachable positioning, and an equivalent access route when required.

Frequently Asked Questions

For a digital QR graphic required to understand or use a web page, WCAG 2.2 Success Criterion 1.4.11 calls for at least 3:1 contrast against adjacent colors. It is not a blanket print rule. Physical codes should use stronger contrast where practical and be tested in their final setting.

The answer depends on the service, jurisdiction, and user need. The EAA and ADA impose scoped accessibility or effective-communication duties rather than a universal QR-specific ban. A readable URL, telephone option, accessible website, or staff-assisted route may be needed to provide equivalent access in a covered context.

No single mounting height fits every jurisdiction and setting. Put the code within the reach and sight range of intended users, avoid glare and obstructions, and check applicable building or signage rules. Test the placement with wheelchair users and people using camera magnification before permanent installation.

Describe the action and destination, not the square pattern itself—for example, “QR code to download the allergen menu PDF.” If the adjacent link already provides the same action, avoid redundant wording. The destination must also be available as an ordinary accessible link so scanning is not required online.
