## 🚀 Quick Implementation Guide

### For Frontend Developers
```javascript
// Step 1: Receive card from ABHA verify response
const response = await fetch('/abha/verify', { /* ... */ });
const data = await response.json();

// Step 2: Get card data
const cardBase64 = data.card_base64;
const cardContentType = data.card_content_type || 'image/png';

// Step 3: Create displayable URL
const dataUrl = `data:${cardContentType};base64,${cardBase64}`;

// Step 4: Display in HTML
document.getElementById('abhaCardImage').src = dataUrl;
```

### For Backend Developers
```php
// Card data is automatically extracted by:
// 1. extractAbhaCardData($result) → returns Base64 string
// 2. resolveAbhaCardContentType($result) → returns "image/png"
// 3. resolveAbhaCardSource($result) → returns "abdm" or "provisional"

// Already implemented in:
// - Abha::verifyOtp()
// - Abha::verifyCommOtp()
```

## 🐛 Troubleshooting

### Card Not Displaying?
1. Check if `card_base64` is in response
2. Verify `card_content_type` is set
3. Inspect browser console for JS errors
4. Check CSS for display/visibility issues

### Card Download Not Working?
1. Ensure data URL is properly formatted
2. Check browser console for errors
3. Verify `href` attribute on download link
4. Test in different browser

### "Provisional Card" Warning?
1. This is correct - bridge-generated cards show this
2. Only official ABDM cards show no warning
3. Both types are functional
