✨Intelligent QR Code Generation & ManagementPRO

• Smart Generation: Click "Generate QR Code" to create a new code. The system automatically handles the rest.
• Duplicate Prevention with Auto-Retry: If a generated code already exists, the system intelligently adds a suffix (e.g., _1, _2) and retries until a unique code is found.
• Safe Regeneration: The "Generate" button will not overwrite an existing QR code, preventing accidental data loss. A notification will prompt you to clear the field first.
• Automatic Form Reload: After generating a code or image, the form instantly reloads to display the new data, providing immediate visual feedback.
• User-Friendly Notifications: Receive clear success, warning, or error notifications for every action.
