Smart key is a specially designed for those who are bothered by a bunch of keys. It's unique due to the employment of the PFID technique,which connects the key with the lock. The induction piont on the key gives out green light as long as it is about 1 m to the corresponding lock. This feature frees you from trying a long time finding the right key as well as missing the key in the dark. Opening the door will no longer be a inconvienience with our new product. It's particularly suitable for room management, like dormitory janitors.
