The present invention is a system and method of pre-delivery drug identification. The filter system sensor provides information to the control system relating to the type of the at least one filter system upon fluid connection thereof with the housing. Additional embodiments involve depositing multiple layers of conductive material within the opening and above the insulating layer, where one of the conductive layers includes aluminum and is deposited using a cold aluminum process, and a second one of the conductive layers also includes aluminum, but is deposited using a hot aluminum process.
