Dynamic QR Codes for Presentations and Talks

Give your audience slides, links, or a live poll in one scan, and change the destination before, during, or after the talk.

Dynamic: change where the code points after printing, and see how many people scan it.

Create the code to get your scannable dynamic QR.

Presenters constantly promise to "share the slides afterward," then lose track of who asked. A QR code on screen hands everyone the material on the spot: the deck, the report you cited, a sign-up form, or your contact card. People scan while you are still talking and leave with the thing they actually wanted.

Static codes have an awkward flaw here. Decks are finalized at the last minute, files move, and the follow-up page often does not exist until after the talk. A dynamic code can sit in your slides from the first draft, pointing to a holding page, and you change the destination whenever the real material is ready.

Why use a dynamic QR code for presentations

Add the code before content exists

Put the code in your deck while the slides are still being written. Point it at a holding page, then switch it to the final file or recording after the talk without touching the presentation.

Change it mid-talk

Use one code for several moments: a live poll during the session, then the slides at the end. Update the destination from your phone between sections while the code stays on your template.

Reuse across many talks

Speakers who give the same talk repeatedly can keep a single code in the template and point it at each event's resources. Old printed handouts from previous events still resolve to something useful.

See how engaged the room was

Scan totals and the daily trend show how many people grabbed the material during and after the talk, and the device split hints at whether they scanned from phones or later on laptops.

How to set it up

  1. Decide what the audience needs most: the slides, a resource page, a poll, or a contact form. A single page that collects all of these works well if you have several things to share.
  2. Paste the link, or a placeholder page if the content is not ready, and name the code after the talk. Download the SVG so it stays sharp on high-resolution projectors.
  3. Place the code on your opening and closing slides, and in any printed handout. Save the manage link on your phone so you can repoint it from the stage if needed.
  4. Rehearse the scan from the back of the room or with the slide shared on a call. Confirm the link opens without a login, and switch it to the final destination when ready.

Where to place it

  • On the title slide, so early arrivals can grab the agenda and resources before you begin.
  • On the closing slide, left on screen during questions, linking to the deck and follow-up material.
  • In the corner of every slide during a long workshop, so latecomers can catch up.
  • On printed handouts or seat cards, pointing to the session recording once it is published.
  • On the speaker banner or lectern sign at an event, opening your talk page and contact details.

Tips that improve scans

Give people time to scan

Leave the code on screen for at least 20 to 30 seconds and say out loud what it opens. Flashing it for a moment means half the room is still unlocking their phones when it disappears.

Size for the back row

On a projected slide, make the code roughly a quarter of the screen height with plenty of white space around it. Test from the farthest seat; small codes on busy backgrounds fail at distance.

Use a clear promise

"Scan for the slides and the full checklist" is more compelling than "Scan for more info." Concrete value gets more scans and sets the right expectation.

Avoid gated downloads

If you require an email address before the slides download, say so on screen. Audiences feel misled when an apparently free resource suddenly asks for personal details, and many will simply leave.

Slides that were not finished

A product manager was asked to present a roadmap at an internal all-hands with two days' notice. She added a QR code to the closing slide pointing at a page that read "Slides coming after the session." After the talk, a colleague pointed out a wrong date on one slide. She fixed it, exported the corrected deck, and pointed the code at that file. Everyone who scanned during the meeting and afterward received the accurate version, and the recorded presentation never showed a broken or outdated link.

Frequently asked questions

Can I change the link while presenting?

Yes. Open the manage link on your phone or laptop and update the destination; new scans go to the new page immediately. People who already opened the old page need to scan again to see it.

Does the code work on video calls?

Yes. Remote attendees can scan the code from their screen with a phone. Make it large on the slide and also paste the link in the chat for anyone watching on the same phone they would scan with.

Should I put the code on every slide?

For short talks, the opening and closing slides are enough. For long workshops with people arriving and leaving, a small code in a consistent corner of every slide helps without distracting.

Can I see who scanned?

No. You get total scans, scans per day, top countries, and device types, but no personal data. If you need attendee details, link to a form that asks for them with consent.
