QR Code Accessibility: Making Campaigns Inclusive for Blind and Low-Vision Users

1. The Core Problem

A QR code is a visual symbol. Blind users cannot see it, and low-vision users may struggle to frame it in the camera. Any campaign relying solely on QR excludes this group.

2. Always Include the URL

Print the destination URL in plain, readable text near the code. A user who cannot scan can type it. A short domain path (example.com/menu) is both typeable and screenreader-friendly.

3. ARIA on the Web

When embedding a QR code image on a web page, add descriptive alt text explaining the destination: `alt="Scan to open the event registration form, or visit example.com/register"`. This communicates purpose to screen reader users.

4. Tactile Markers

Some signage operators add a small tactile indicator near the QR code as a location marker for people using a long cane. This helps find the sign but does not help with the scan.

5. Multiple Channels

Offer the same information by phone, email, and web URL in addition to QR. Accessibility law in many markets requires equivalent access.
