## 🔒 Security Considerations

### **Sensitive Data:**

- Default passwords (Member@2025)
- Membership card numbers

### **Recommendations:**
1. ✅ Share PDFs via **secure channels** only
2. ✅ **Delete** PDFs after credential distribution
3. ✅ Advise members to **change passwords** immediately
4. ✅ **Don't email** PDFs to unsecured addresses
5. ✅ Consider implementing **password-protected PDFs** (future enhancement)

## 🐛 Troubleshooting

### **"Export to PDF" button not showing**
**Solution:** Upload members first - button only appears after successful upload

### **PDF download fails**
**Solution:** 
- Check TCPDF is installed: `composer require tecnickcom/tcpdf`
- Verify `vendor/tecnickcom/tcpdf/` folder exists
- Check PHP memory limit (increase if needed)

### **PDF shows no data**
**Solution:**
- Ensure upload was successful
- Check session data exists
- Try uploading again

### **Class 'TCPDF' not found**
**Solution:** Run `composer install` to install dependencies
