The cabinet housing has a locking mechanism, and the controller is in communication with the cabinet housing and configured to operate the locking mechanism. The drawer unit is designed to be releasably locked at least partially within the cabinet housing by the locking mechanism, and slidable within a portion of the cabinet housing when released by the locking mechanism. The drawer unit includes at least one storage compartment, a cover, memory, and a power source. The storage compartment is configured to store at least one item therein. The cover is movable to an open configuration and a closed configuration. When the cover is in the closed configuration, the cover limits access to the item of the storage compartment. The memory is powered by the power source and is configured to store data associated with a movement of the cover.
