How to Use LinkedIn QR Code in Presentations and Slides

When to include a QR code is a matter of presentation pacing. Never put a QR code on your title slide. While people are finding their seats, they are not yet invested in connecting with you. The optimal time to introduce the QR code is on the final "Thank You" or "Q&A" slide. By this point, you have delivered value, established authority, and given the audience a reason to want to follow your future work. Leaving the code on screen for the 5-10 minutes of Q&A gives everyone ample time to scan.

Slide placement governs scannability from the back of the room. Do not place the QR code in the bottom corners of the slide, as audience heads and seating arrangements often block the lower third of a projector screen. Place the QR code in the upper left or upper right quadrant of the screen. Ensure there is extreme high contrast between the code (dark) and the slide background (light). Never place a QR code over a busy photographic background.

Size for scanning in a presentation context is drastically different than on a business card. A QR code on a projector screen must be massive to be scannable from row 20. The general rule of thumb is a 10:1 ratio. If the furtheset viewer is 30 feet (360 inches) away, the QR code on the physical screen needs to be 36 inches wide. On your actual slide file, the code should take up at least 25% of the slide real estate. Test this before the presentation by standing at the back of the room during AV check.

The Call to Action (CTA) must be specific. "Scan this" is a weak CTA. Tell the audience exactly what value they receive by scanning. "Scan to download these slides and connect," or "Scan to get the 3 templates I just discussed." A value-driven CTA increases scan rates by 300% compared to a naked QR code. Promise a specific digital asset that lives on your LinkedIn profile (e.g., in your Featured section) to incentivize the immediate connection.

Examples of effective presentation strategies: The "Resource Slide." Instead of listing 10 URLs that nobody will write down, have one slide titled "Resources" with a giant QR code that links to a LinkedIn post where you have already linked all the resources. The "Continuing the Conversation Slide." During a polarizing or highly technical talk, end with: "We don't have time to cover everything. Scan this to connect with me on LinkedIn where I am posting the full technical breakdown tomorrow morning."
