Abstract: A pass-through transaction drawer with a hinged, moveable security flap is disclosed to permit the conveyance of articles, in a relatively secure manner, between an attendant or clerk within a building and a customer outside the building irrespective of the drawer size or depth. The hinged, moveable security flap is only moveable by the attendant to maximize security. The security flap can be adapted with a small contents tray to facilitate transactions involving the exchange of money or credit cards. To facilitate transactions which may require deeper transaction drawers, the transaction drawer may be adapted with an interior partition to compartmentalize a relatively deep drawer, whereby relatively larger, bulky items are conveyed in the deeper compartment and smaller articles are conveyed in the shallow compartment.
