The self-check-in feature on Busitema University's Online Public Access Catalog likely allows users to return library materials independently. Users can access the catalog using libcat.busitema.ac.ug, and after logging in with their catalog Log in credentials, they can then navigate to the self-check-in section. In this section, users can interact with the system to initiate the return process. This  involves scanning the barcodes or RFID tags of the items they want to return. The system will then update the user's library account, marking the returned items as checked in. Users may also receive a confirmation message on their emails  that the return was successful. This self-check-in process enhances user convenience by allowing them to complete the return without needing to wait in line at the library's circulation desk.
