What is a QR Code?
Quick Response (QR) codes are barcodes that users can scan with a mobile device camera to access a web page. This makes them particularly useful in print media, like posters, flyers, and postcards.
However, QR codes should be avoided in most online contexts because if a mobile user receives an email, e-newsletter, or views a web page with a QR code, they cannot view the content and scan the code at the same time on their device.
QR Code Accessibility Best Practices
Ensure Scannability: Use high contrast between the QR code and the background and avoid overly complex designs. This makes it easier for people with visual impairments to scan the code.
Include the link: Provide the link in text near the QR code so that users who cannot scan it, either due to accessibility issues or technical limitations, can still access the information by manually typing the web address or using assistive technologies like voice commands or screen readers to navigate directly to the link.
Placement: When placing a QR code on a banner or signage, ensure it is accessible to people using wheelchairs and is easy to scan. Avoid placing it in hard-to-reach or difficult-to-scan locations.
