[0059] Reference Fig.11 A control method for storing a compact rack for confidential items comprises the following steps:

[0060] The first step is to determine the files that need to be reviewed and the items that need to be collected;

[0061] In the second step, the approval system determines the identity information of the staff who review the files and receive the items;

[0062] The third step is to submit the information of checking the files and picking up the items to the supervisor for approval;

[0063] Step 4: The camera 511 and the fingerprint collection component 512 of the compact rack collect the identity information of the staff who picks up the items. The camera 511 and the fingerprint collection component 512 of the compact rack collect the identity information of the staff who picks up the items. The collected data is processed by the data collection module 52 and then transmitted to the data processing module 54 for data processing;

[0064] In the fifth step, the data processing module 54 transmits the processed information to the control module 56, and the control module 56 controls the electronic lock 22 or the electromagnetic lock 43 to operate so that the staff can take away the products or files they need to collect.

[0065] After the staff has determined all the confidential items to be collected, they submit their requirements through the management system (such as DingTalk system or other systems). The system sets permissions, and staff who do not have the authority to collect confidential items do not have the authority to submit applications. After the authorized staff submits the application, the upper level will review and approve it. After the approval is passed, the demand information will be transmitted to the compact shelving. The communication module 55 receives the relevant information and transmits the information to the data processing module 52 for processing. The staff who submitted the application obtains the access right to the compact shelving. If the approval is not passed, the staff who submitted the application cannot obtain the access right.

[0066] When the staff member who has made an application arrives at the compact shelving, the camera 511 and fingerprint collection component 512 of the compact shelving simultaneously collect the identity information of the staff member who collects the items. The collected data is processed by the data collection module 52 and then transmitted to the data processing module 54 for processing. The data processing module 54 transmits the processed information to the control module 56. The control module 56 controls the electronic lock 22 or the electromagnetic lock 43 to operate, so that the staff member can take away the required products or files. If the fingerprint information of the staff member does not match the portrait information, the required products or files cannot be taken away, thereby avoiding the leakage of confidential information.
