6 Best Ways to Collect Event Attendee Data for B2B Marketers
For years, the badge scanner has been a staple of the event marketer’s arsenal. Unfortunately, these days, they’re no longer enough.
They only capture people who actively agree to be scanned—missing the large number of event attendees who hover, engage, and walk away untracked.
Moreover, badge scan data is usually limited and often inaccurate. It doesn’t tell you what a person was actually interested in. Did they linger at your product demo or just stop by for the swag? Did they match your ICP? Traditional scans won’t answer that.
Put simply, if you’re relying on badge scans to gather event attendee data, you’re likely leaving your most engaged leads behind without even realizing it.
In this post, we’re diving into the best ways to collect event attendee data, so you can walk away from your next trade show with intel you can actually use.
1. Target attendees before they even show up
Your data collection strategy should start before the show floor opens.
Use intent data and behavioral signals to identify high-fit accounts researching your solution or the event itself.
Serve digital ads that drive booth interest. Use tracking pixels to capture traffic data and ad engagement.
This helps you warm up your audience early. You’ll not only get more booth traffic, you’ll know in advance who your highest-value visitors are likely to be. You can use this information to prioritize meetings, prepare custom demos, or coordinate with sales to follow up fast.
2. Geofence your venue and nearby locations
One of the best ways to collect event attendee data is often overlooked in the B2B space: geofencing.
By placing a digital “fence” around your booth or venue, you can serve targeted ads in real time, capture anonymous device signals, and, with the right solution (like ViB Digital for Tradeshows), resolve those signals into enriched contact information.
Pro tip: Don’t stop at the venue. Geofence the airport, nearby hotels, popular bars, coffee shops, etc. This way, you can capture attention even outside of the conference center.
Also, set specific perimeters in key locations within the venue—for instance, your booth, your competitors’ booths, and relevant keynote sessions. This way, you’re targeting people you know are actively looking for a solution like yours.
3. Use in-booth experiences to capture richer data
Static booths are a thing of the past. Today’s best booths engage and gather intel at the same time.
Here’s how:
These tactics not only attract visitors, they give you deeper insight into what they care about. For example, a short quiz that maps a visitor’s top challenge (e.g., lead quality, conversion rates, attribution) gives your team a talking point—and gives you better segmentation data later.
Pro tip: Make sure your booth staff is trained to collect the right info. Every conversation should serve both the attendee and your data goals.
4. Track ad and landing page engagement
Don’t forget about your digital footprint during the event.
Serving ads to attendees (especially those near your booth) is great—but what happens when they visit your landing page and don’t fill out a form?
You can still track their visit, resolve their identity (with the right partner), and enrich their data for follow-up.
ViB Digital for Tradeshows uses an advanced tracking pixel to identify who’s engaging with your content, even if they never convert on-site. This means you’re not limited to form fills to know who’s interested.
5. Use QR codes (but make them smarter)
QR codes aren’t just for menus anymore.
They can give you an easy, low-friction way to collect contact info or drive engagement.
Try this:
The key is tracking. A generic QR code to your homepage won’t cut it. Use dynamic QR codes that capture key metadata like time, location, and campaign source—so you know who scanned what and when.
6. Enrich your post-event data
The goal isn’t just to follow up—it’s to follow up smart. For example, instead of blasting a generic “Thanks for visiting our booth” email, you could send tailored follow-ups by role, industry, or problem area.
Look for tools or partners that can:
That’s what we do at ViB: After each event, we send you a firmographically enriched contact list of all resolved visitors—so your sales team can follow up with precision.

At the end of the day, it’s not about gathering the most data—it’s about gathering the most relevant data.
Modern marketers can’t afford to guess who visited their booth or hope a badge scan tells the full story. With the best ways to collect event attendee data—like geofencing, intent-based targeting, identity resolution, and firmographic enrichment—you can finally turn anonymous foot traffic into real, high-fit leads.
