AN ATM comprises a card reader (60) having a transport path (62) and a card entry slot (65) at one end of the transport path for receiving a user identification card from an ATM user. A maintenance card (99) resides in a position adjoining the card reader and is movable between a resting position and a testing position along the transport path of the card reader. A transport mechanism (57,60,70,72,74, 76,94)moves the card between the two positions under the control of a processor unit (28) in response to testing command signals received from the remote terminal. The maintenance card is substantially identical in size to a standard magnetic stripe card. Either the card is a diagnostic card which performs a maintenance operation of the card reader, or the card is a cleaning type of card which is moved to clean parts of the card reader, or the card is a fraud tool detection card which, if it cannot be moved between the resting and testing positions, indicates the presence of a fraud tool. <IMAGE> |
