Abstract:
1. A self-serving banking machine comprising: a card reader; a display; control circuitry for controlling the operation of said machine including said card reader and said display; and an abnormality detector system associated with said card reader; wherein said abnormality detector system comprises: an antenna adapted to receive signals representing an electromagnetic field around the card reader; a sensor electronically coupled to said antenna which monitors and decodes the signals received by the antenna, wherein by monitoring said signals said sensor can detect an abnormality in said electromagnetic field as such abnormality occurs; and an electronic control board which is coupled to said sensor for receiving the information decoded by the sensor and for determining whether such information represents a normal electromagnetic field or an abnormal electromagnetic field; wherein said control board transmits signals to said control circuitry representing an indication of either normal or abnormal card reader conditions; wherein said control circuitry may allow normal operation of said display only while receiving signals indicating normal conditions; and wherein said control circuitry, in response to receiving a signal indicating a change from normal condition to abnormal condition, either deactivates the display or changes such display to a maintenance mode, thereby preventing users from using said machine.
