🎯 Key Findings

Finding 1: Card Data in Bridge Response ✅

Bridge returns official ABHA card in multiple fields:

  • official_card (Base64 PNG)
  • card_data (Base64 PNG)
  • abhaCard (Base64 PNG)
  • card_format ("png")

Finding 2: HMS Extracts Automatically ✅

EAtriaBridgeConnector handles:

  • Multiple field names
  • Nested structures
  • Data URL conversion
  • Content-type detection
  • Source tracking (official vs provisional)

Finding 3: Card Displays Everywhere ✅

Implemented in modals:

  • abha_verify_modal.php - Verification flow
  • abha_create_modal.php - Creation flow
  • abha_mobile_modal.php - Mobile OTP flow
  • abha_patient_match_modal.php - Patient matching

Finding 4: Card View Ready for Printing ✅

Dedicated view:

  • app/Views/abha/card.php
  • Shows official card image
  • Includes patient HMS ID
  • Shows QR code
  • Print-ready layout

Finding 5: Bridge Message Validated ✅

Bridge states: "HMS integration can now seamlessly consume official_card / card_data_uri across all verification routes."

Result: CONFIRMED - Both work as documented

🚀 User Flows Implemented

Flow 1: ABHA Creation with Card

1. User starts ABHA creation
2. Selects OTP verification method
3. Verifies OTP
4. Bridge returns card + profile
5. Modal displays:
   ✅ Profile photo
   ✅ Official ABHA card image
   ✅ Verification details
6. User clicks "Download ABHA Card"
7. Browser saves PNG file

Flow 2: View Patient Card

1. Open patient profile
2. Click "View/Print ABHA Card"
3. Opens: /abha/card/{abha_number}
4. View displays:
   ✅ Official ABHA card image
   ✅ Patient HMS ID with barcode
   ✅ QR code
   ✅ Hospital branding
5. User prints or saves as PDF

Flow 3: Explicit Card Download

1. Call API: GET /abha/card/{abha_number}
2. HMS retrieves stored card
3. Renders card view
4. User downloads/prints

💡 Implementation Insights

Smart Card Fetching

  • Card returned in verify response? → Use immediately
  • Card missing? → Call /v3/abha/card endpoint
  • Multiple field names? → Try all 8 variants
  • No data prefix? → Add data:image/png;base64, automatically

Flexible Field Handling

Bridge may return card under:

  • official_card (most common)
  • card_data_uri (alternative naming)
  • card_base64 (explicit Base64)
  • card_data (generic field)
  • abhaCard (camelCase variant)
  • abha_card (snake_case variant)
  • cardData (alternative camelCase)
  • card (generic short name)

HMS handles all variants automatically.

User Experience

  • Card displays immediately if in response
  • Falls back to gateway call if needed
  • Download link always available when card present
  • Helpful fallback message when card unavailable
  • Visual indicator for provisional vs official cards

🔐 Security & Compliance

Authentication

  • ✅ Hospital API key in Authorization header
  • ✅ Patient X-Token in X-Token header when available
  • ✅ Secure card transmission via HTTPS
  • ✅ Card stored securely in database

Data Protection

  • ✅ Card data is Base64 (not encrypted, but safe for image)
  • ✅ PII redacted in logs
  • ✅ Card stored locally to avoid repeated API calls
  • ✅ Access controlled via permission system

Compliance

  • ✅ ABDM Bridge v3 specification compliant
  • ✅ Industry-standard image encoding (Base64 PNG)
  • ✅ Standard data URL format
  • ✅ Proper error handling
