A banking system machine is controlled responsive to data read from data bearing records. The machine includes a card reader, a keypad, a cash dispenser, a cash outlet, a deposit accepting opening, and other transaction locations that may be susceptible to the installation of fraudulent devices adjacent thereto. Such unauthorized devices may include for example, a fraudulent card reading device, a fraudulent keypad input intercepting device, a cash outlet trap device, a deposit input diversion device, or other illegitimate devices. The machine includes an anti-fraud arrangement that is operative to deter the attachment of unauthorized devices to the machine. The arrangement can sense and/or dislodge an unauthorized device attached to the machine. The arrangement also allows for the machine's card slot bezel to be frequently exchanged for a differently contoured card slot bezel.
