Lead Capture FAQ
- Which event platforms are supported?
- CVENT, Eventbrite, ExpoCad, a2z Events, Swoogo, Aventri, and most platforms that generate standard QR or NFC badges.
- How does OCR handle non-English business cards?
- Our OCR model supports Latin, Devanagari (Hindi), and CJK scripts. Non-supported scripts fall back to manual review.
- Can I customise which CRM fields are populated?
- Yes — in Settings → Exhibition → Field Mapping, you can map any badge field to any custom CRM field.
- What's the deduplication logic?
- Email is the primary match key. If a match is found, the existing contact is updated rather than duplicated. Company is a secondary match key.
- Can I add custom questions during scanning?
- Yes — create a Scan Form with up to 5 custom questions. Reps answer them immediately after each scan (e.g. interest level, product discussed).
