When many users come to communicate with us, they may ask some questions, such as whether you have a key cabinet. In fact, there are different types of application scenarios for key cabinets. Taking the management of public security car keys as an example, their car keys may be dozens of cars, authorized to be issued at a police station, and after use, they will be returned. If it is the VDC of the main factory, it may be the car keys of thousands of cars. After parking in its parking space, it is placed in the key room.
