QR codes (or Quick Response codes) are machine-scannable images that can be read with a smartphone camera. They commonly contain links to websites and can quickly connect users to a URL. QR codes can be found on printed posters, flyers, post cards, or presentation slides to direct users to more information on a given topic.
What to consider
When using QR codes:
- Keep URLs short. Short URLs mean less information is contained in the QR code making it easier to read. Note that any changes to a web page's address will break the QR code unless redirected.
- QR codes are meant for printed materials, presentations, or in-person situations where people are more likely to use their phones to quickly access as web page. Avoid using QR codes on websites, social media, or emails: Users can click hyperlinks on those platforms.
- Track your usage. Measure your QR code usage to see how your marketing efforts are working.
Accessibility
Like all other components of federal publications, QR codes should be Section 508 compliant. For QR codes, these best practices should be followed:
- Include what the QR code links to (the original URL, email address, etc.) in text adjacent to the code.
- When considering QR code placement on a banner or signage, place it somewhere that is also accessible to people using wheelchairs. Never place it somewhere that is difficult to scan.
