An ATM (10) includes a housing (46) including a generally L-shaped chest portion (48) and an upper housing portion (54). The ATM includes a fascia (12) which extends on the outside of a wall (14) and includes a user interface (15). Responsive to inputs of a user through the user interface the machine is operative to accept a stack of sheets (84) which are evaluated through operation of a sheet validator device (88) and which enables acceptable sheets to be stored within the chest portion. Unacceptable sheets are routed to a storage area (100). Provisions are made for reducing the risk of attack on the ATM by criminals and to facilitate servicing by authorized personnel.
