QR Codes for Presentations

Speaking in conferences is a great opportunity to present the results of your research and share new knowledge. In this article, we are going to walk you through how you can leverage the power of QR Codes for presentations during conferences and seminars. QR Codes can help you engage with your audience, share important information, and network with those in your field.

What are QR Codes?

QR Codes are two-dimensional barcodes that can be scanned using a smartphone camera. They can contain a lot of information in different formats, like alphanumeric characters, URLs, phone numbers, images, PDF, audio, and more.

They were first created in Japan in the mid-1990s, but did not take off in terms of popularity until the onset of the Covid-19 pandemic. Part of the reason for their popularity is their ability to conduct contactless transactions, which is crucial during a health emergency. In addition, modern smartphone models are also now able to scan QR Codes on their built-in camera without a dedicated application.

QR Codes have now become so popular that we can now see them in billboards, digital and print advertisements, restaurants, stores, schools, libraries, museums, train stations, and more. They are easy-to-make without any coding knowledge using any QR Code generator available for free. This makes them an affordable solution to share files and details when you are speaking in conferences. Static QR Codes – permanent QR Codes that cannot be edited – will go a long way in upgrading your presentation by allowing participants to view related videos, download resources, and get your professional contact details.

How to Use QR Codes for Presentations

Whether you are presenting with a PowerPoint or a poster, QR Codes give you the ability to share more resources and engage with your audience during conferences. There are multiple ways to integrate QR Codes into your presentation.

PowerPoint (and Similar)

If you were invited as a presenter onstage, you would have to prepare a PowerPoint or similar presentation. Here’s how you can make use of QR Codes when presenting:

  • Link audience to a survey site.
  • Allow the audience to download your presentation using a PDF Link.
  • Encourage additional questions by providing your vCard


Many conferences also invite poster presenters. If you’ve been selected as one, here are some of the ways you can integrate QR Codes into your poster.

  • Invite your audience to watch a time-lapse video of your experiment.
  • Invite your audience to download your full paper.
  • Invite your audience to reach out to you with your vCard.
