Drop-boxes provide access control to one door in Full Anti-passback Mode (APB) by using the Antenna Reader connected to "Reader 2" as the incoming Reader, and the Drop Box as the outgoing Reader. Alternatively, use "Reader 2" as the outgoing Reader for permanent Tagholders, and the Drop Box as the outgoing Reader for visitor Tagholders.
