# Cardo — Turn Visiting Cards Into Digital Contacts

> Cardo is an AI-powered visiting and business card digitization application that uses Google Gemini Multimodal Vision AI to accurately extract contact details, organize them with event tags and relationship context, and sync automatically to Google Sheets.

## Core Capabilities
- **AI Camera & Gallery Scanner**: Instant multimodal OCR powered by Gemini 1.5 Flash. Accurately extracts names, titles, phone numbers, emails, addresses, companies, and websites without hallucination.

- **Event-Based Organization**: Group cards by event (e.g. "Dubai Expo 2026", "TechSparks", "IJS Summit"). Enables rapid batch scanning without retyping tags.
- **Relationship Context Tracking**: Record how met, where met, relationship type (Client, Partner, Vendor, Lead), notes, and follow-up reminders.
- **WhatsApp One-Click Sharing**: One-tap export and messaging directly to scanned contacts via WhatsApp.
- **Privacy & Security**: Zero Contact PII stored in analytics. Server-side quota validation with OAuth 2.0 Google Sign-In.
