QR Codes for Accessibility

Printable version of this page

A QR ("Quick Response") code is an optical, two-dimensional barcode that is easily readable by computers or smartphones with a camera.

QR codes are another way of making materials more accessible to everyone. Including QR codes on presentations, handouts, fliers, and posters would allow students to scan the QR code and download an electronic version of that document. Of course, the electronic version first needs to be made in an accessible format - otherwise, assistive technology will be unable to read it correctly.

Advantages of QR Codes

Unfortunately, there is still a stigma around disabilities. Many students who would benefit from receiving accommodations through the Center for Accessibility Resources are reluctant to request these accommodations. By making accessible electronic documents available for download to all students in the class, those students can benefit. In addition to these students, having electronic documents available can also be beneficial for students without disabilities depending on their unique learning styles.

QR barcode scanners are surprisingly sensitive and forgiving. The camera does not need to be particularly close to the code to pick up the information and redirect the machine to the appropriate content.

Using QR codes during presentations or lectures is often much quicker than having the students type in a web address or sign in to Google accounts.

Free QR code generators are available and simple to use. Those with minimal technology skills can easily master the use of QR codes.

Distribution of materials can be regulated by who has access to the QR code. It is also possible to cancel the code after a presentation or lecture. This would not remove access from those that were able to download the file during the time it was active, but will prevent anyone else from gaining access to the materials.

Tips for Using QR Codes

Often times, web addresses can be quite long. This makes the generated QR code more complex and more difficult for scanning apps to recognize. To make this simpler, free URL shortening services can be utilized prior to generating the QR code.

Some file formats such as Google Docs, Slides, and Sheets are not easily made accessible. Because of this, it is usually best to use native file formats such as Microsoft Office.

Visually impaired students may not know that a QR code is visible, so it is important to make an announcement when/if they are used in class.
