A method for prohibiting a person with a facial mask to operate an automatic teller machine essentially includes the followings steps of: a) arranging a visual spectrum camera and an alarm unit approaching an automatic teller machine (ATM); b) capturing a facial picture of an experimental subject via the camera; c) judging if the picture performs generic facial features of a human face; if false, proceed Step g); d) if true, a facial temperature of the subject is detected to gain a measured temperature; e) comparing the measured temperature with a predetermined reference temperature; if the measured temperature is not within the reference temperature range, a spurious human face is determined and Step g) goes on; f) if the measured temperature is within the reference temperature range, a genuine human face is determined and the ATM is allowably operated without proceeding Step g); and g) activating the alarm unit to transmit a warning signal without operating the ATM.
