There are three ways to capture visitor information at open houses: paper sheets, digital tablets, and QR code sign-in. Each has trade-offs in accuracy, cost, privacy, and lead quality. Here’s the data-backed breakdown.

Immediate (auto-sync)
Verification
Optional social lookup
QR Code + Verification

Verification
Google / email / SMS required
Paper Sign-In Sheets: The Old Standard
Paper sign-in sheets have been the default for decades. They’re free, require no technology, and every agent has used them. But the data tells a different story:
- • Up to 40% of contact info is fake or illegible
- • Manual data entry takes 24-48 hours post-event
- • All visitors see previous visitors’ personal information
- • No way to verify or validate contact details
- • Sheets get lost, damaged, or forgotten
Digital Tablet Sign-In: Better, but Limited
Apps like Curb Hero, Spacio, and Open Home Pro let you set up a tablet at the door. Visitors type their info on-screen. This eliminates handwriting issues and enables faster follow-up, but:
- + Digital data — no transcription needed
- + CRM sync via Zapier or direct integration
- + Social profile lookup (Spacio)
- − Visitors can still type fake info
- − Requires a tablet device at every open house
- − One device = bottleneck with multiple visitors
- − Only works at open houses (not yard signs, flyers, etc.)
QR Code + Verification: The Modern Approach
QR code sign-in flips the model: instead of the agent providing a device, the buyer uses their own phone. They scan a QR code, land on a branded listing page, and verify their identity to see full details.
- + ~95% accuracy with identity verification
- + No device to bring, charge, or manage
- + No bottleneck — every visitor scans independently
- + Works on yard signs, flyers, social media, email — not just open houses
- + Private — no one sees other visitors’ information
- + Leads in dashboard instantly with verification status
Side-by-Side Comparison
| Criteria | Paper | Digital Tablet | QR + Verified |
|---|---|---|---|
| Lead accuracy | ~60% | ~80% | ~95% |
| Time to follow up | 24-48 hrs | Immediate | Instant |
| Verification | None | Optional | Required |
| Privacy | Shared sheet | Shared device | Personal phone |
| Hardware needed | Paper + pen | Tablet ($200+) | Printed QR code |
| Works beyond open house | No | No | Yes (all surfaces) |
| Lender co-branding | No | No | Yes |
| Loan calculators | No | No | Yes |
| Cost | Free | $0-$100/mo | $0-$29/mo |
The Verdict
Paper sign-in sheets are outdated and cost you leads. Digital tablet sign-in is a step up but still limited to the open house event and lacks verification. QR code sign-in with identity verification is the clear winner — it captures leads from every marketing surface, verifies every contact, and costs less than tablet-based alternatives.
The best approach for most agents: use QR codes as your primary lead capture method across all marketing (signs, flyers, open houses, social), and keep a tablet as a backup for visitors who are less tech-savvy.
