It’s natural for a home to have multiple guests coming together under the same roof. Hence, the YMF30+ smart lock lets you enter home without needing to remember PIN codes simply because you can use RFID key tags for easy door access. You can even issue single-use temporary passwords for your visitors and set schedules to let them in while you’re away. The voice guide feature that comes with YMF30+ is there to walk you through the step-by-step process on various operations possible on your smart lock, including PIN code scrambling to make your code harder to follow.
