Abstract: An opening in a front panel of an automated teller machine (ATM) normally permits a portion of an internal mechanism to protrude therethrough to receive customer cards or for similar purposes. When the internal mechanism of the ATM is withdrawn for servicing, the protruding portion of the mechanism is withdrawn from the opening. A vertically slidable door is provided to close said opening whenever said protruding portion is withdrawn, in order to prevent access to the interior of the ATM by unauthorized persons. The door is operated by mechanism responsive to the movement of the internal mechanism.

Abstract: A credit card operable storage system is provided. A plurality of credit card accessed and computer operated safes are communicatively linked to a respective branch computer, which is in turn communicatively linked to a central host computer (central host). The safes transmit use information (including credit card informaton) to their respective branch computers where the information is stored and periodically transmitted to the central host. The central host processes the use information into billing information which is electronically transmitted to a billing statement generating system.
