First, the unlocking method is to use a two-dimensional code to open, whether it supports other unlocking methods, such as mechanical keys or cards or fingerprints, these can be negotiated with us.
Second, convenience. It`s easy to lose keys and proximity cards. It`s troublesome to go out for a run, but mobile phones have become as important as our organs. When we use our mobile phones to get the QR code to open the door, we won`t lose them. Open it directly and swipe the door very convenient. If you share the key with your friends, you can set the number of unlocking times, the time limit for unlocking, etc. Anyway, who can open it and how long it will last is all up to you. No more silly going downstairs to pick up guests.
The third is to facilitate management. Its software has functions such as key sharing, management, access control record viewing, and role unlocking authority. It is suitable for places such as hotel apartments that require strict management of a large number of entrance guards and rooms.
