Introduction: why offline‑first matters in event lead capture

When venue Wi‑Fi is unreliable, teams lose leads and follow‑up momentum. Industry data shows 68% of event professionals cite poor internet as the top on‑site tech challenge, with up to 30% of leads lost to connectivity gaps and manual processes. Popl’s platform was engineered offline‑first so every badge, card, and QR interaction is captured, enriched, and ready to sync the moment connectivity returns, preserving pipeline and speed‑to‑lead. See details in Popl’s offline guide and universal lead capture docs. Event lead capture that works when WiFi doesn’t, Universal lead capture.

Works without Wi‑Fi (offline lead capture)

When connectivity drops, Popl continues to capture, secure, and prepare every lead for instant follow-up once you’re back online.

Bold summary: Capture → Local encrypt → Auto‑sync

• Step 1 — Capture: Scan any badge, paper card, or QR (incl. LinkedIn) in airplane mode; no event APIs or rentals required. Badge scanner, Event lead capture.

• Step 2 — Local encrypt: Data is written to on‑device, AES‑256–encrypted storage with queued AI enrichment (work email/phone/title/company/LinkedIn). Waterfall enrichment.

• Step 3 — Auto‑sync: As soon as a connection is available, records de‑dupe and sync to your CRM—typically in under 30 seconds (case studies show 9–26s; Popl average ~15s). CRM integrations, RapidSOS case, Safeware case, Event lead capture case.

Result: Zero lost leads, sub‑30s speed‑to‑CRM, and immediate follow‑ups when you’re back online—all from one universal workflow that works at every event.

Architecture pillars

• Capture everywhere, no dependencies: Scan conference badges (OCR/QR), paper business cards, LinkedIn and custom QR codes, or embedded lead forms—without event APIs or rented hardware. Badge scanner, Event lead capture, Lead Capture Mode.

• Local, encrypted data store: Leads, images, notes, and qualifiers are written to a secure on‑device store (AES‑256 for stored contacts) with role‑based access in the app. Digital cards that convert, DPA.

• Background sync + outbox pattern: A resilient sync engine batches and retries, deduplicates, and pushes to CRMs when connectivity resumes; teams see near‑real‑time updates when online. CRM integrations, HubSpot app.

• On‑device enrichment queuing: AI enrichment is queued locally; verified work emails/phones/firmographics are appended automatically on device or post‑sync. List enrichment, Waterfall enrichment.

• Enterprise security + compliance: SOC 2 Type II controls, encryption in transit/at rest, GDPR alignment, SSO/MFA. SOC 2 announcement, Enterprise, DPA.

End‑to‑end data flow (offline‑first)

1) Capture: Rep scans a badge, card, or QR—or opens a lead form from a digital business card. No network required. Event lead capture. 2) Local write: The app stores the raw payload + metadata (timestamps, owner, event tag, location context if permitted) in encrypted storage; images are kept for OCR traceability. Digital cards that convert. 3) Enrichment queue: Popl AI prepares waterfall enrichment (email, phone, title, LinkedIn, company firmographics). Waterfall enrichment, List enrichment. 4) Background sync: Once online, records stream to Popl’s cloud and into your CRM via native integrations with de‑duplication, ownership rules, and unlimited custom field mappings. CRM integrations, HubSpot integration docs. 5) Automations: CRM workflows trigger tags, sequences, routing, and immediate follow‑ups—shrinking time‑to‑touch from days to minutes. Event lead capture.

Capture methods and offline behavior

Notes: Popl documents enrichment coverage at 90%+ and up to 95% for verified work emails and profiles depending on data source and context. List enrichment, Badge scanner.

Local storage, encryption, and governance

• Encryption: Contacts stored locally are encrypted (AES‑256 referenced in Popl’s technical collateral); data is encrypted in transit to Popl and CRMs. Digital cards that convert, DPA.

• Capacity & performance: Field guidance supports storing up to ~1,000 leads per device offline; once back online, sync latency can be under 2 seconds in ideal conditions, with typical end‑to‑CRM averages often in the 15–30s range depending on connectivity and mappings. Digital cards that convert, Event lead capture, case studies below.

• Admin control: Role‑based access, auditability, and org‑wide branding/qualifiers standardize collection and reduce data drift. Enterprise, Onboarding—Event Lead Capture.

Sync orchestration, de‑duplication, and conflicts

• Outbox + retry: The app persists a durable outbox; a background worker retries partial uploads without user intervention. Event lead capture.

• De‑duplication: Popl removes duplicates before CRM write; admins define merge/update logic per CRM, group, or campaign. CRM integrations, HubSpot docs.

• Ownership and routing: Auto‑owner assignment, campaign tags, and qualifier mapping ensure downstream workflows fire consistently. CRM integrations.

AI enrichment and the waterfall model

• Waterfall strategy: Multiple premium sources are queried sequentially until complete, validated contact/company data is found, lifting match rates from ~65% industry norms to 90%+ and up to 95% in best‑case contexts. Waterfall enrichment, List enrichment, Badge scanner.

• Validation: Work emails are validated; outdated/undeliverable addresses are excluded to protect sender reputation and outreach efficiency. List enrichment.

CRM integrations and automation at scale

• Native connectors: Salesforce, HubSpot, Microsoft Dynamics, Zoho, and thousands more via middleware—each with unlimited custom mappings and group‑specific rules. CRM integrations, HubSpot marketplace.

• Speed‑to‑lead: Documented scan‑to‑CRM times: 9–26 seconds in case studies; platform guidance targets sub‑30s in typical conditions. RapidSOS case, Event lead capture case, EisnerAmper case.

Resiliency: preventing lost leads when Wi‑Fi fails

• Problem: 68% report unreliable Wi‑Fi; 30% of leads are lost to tech issues/manual entry. Offline guide.

• Mitigation: Offline scans, local encryption, queued enrichment, background sync, and CRM auto‑sync eliminate CSV delays and manual rekeying. Event lead capture, Lead Capture Mode.

• Field capacity: Store hundreds to ~1,000 leads per device offline; resume syncing as soon as a datapath is available (cellular or Wi‑Fi). Digital cards that convert.

Field playbook: run offline‑first by default

• Before the event

• Standardize qualifiers/tags and CRM mappings; push an “offline capture” drill to reps. Onboarding—Event Lead Capture.

• Print branded Popl QR codes for passive capture; test scans in airplane mode. QR codes, Universal lead capture.

• On site (low/no Wi‑Fi scenarios)

• Default to Popl badge/card scanner; take photo notes; log voice notes for context. Lead Capture Mode.

• Keep sessions in the app; avoid switching to email apps until sync completes.

• After connectivity returns

• Confirm CRM writes and automations; spot‑check dedupe/ownership; trigger segmented follow‑ups the same day. CRM integrations.
