Claim:
A game facility monitoring system comprising: a plurality of game machines and game-related devices, at least one of the game machines and game-related devices including means for providing a transaction with a person, upon input by the person of identification information identifying the person, means for detecting disagreement between identifying information input and previously recorded identifying information, means for assigning one of a plurality of anomaly levels based on degree of disagreement between the identification information input and the previously recorded identification information, wherein each of the anomaly levels indicates a different, respective probability of a fraudulent transaction, a first of the anomaly levels represents a non-fraudulent transaction, a second of the anomaly levels represents a potentially fraudulent transaction, and third of the anomaly levels represents a fraudulent transaction, and a camera capturing an image of a person attempting a transaction only when the transaction attempted has an anomaly level exceeding a threshold anomaly level; and a computer connected to the at least one of the game machines and the game-related devices for recording transactions and, when the threshold anomaly level has been exceeded, a captured image of the person, wherein the computer includes a processor programmed so that, in response to assigning the first of the anomaly levels to a disagreement, to permit completion of the associated non-fraudulent transaction, in response to assigning the second of the anomaly levels to a disagreement, to trigger the camera to capture an image of the person attempting the associated potentially fraudulent transaction and to record transaction information for later review, and in response to assigning the third of the anomaly levels to a disagreement, to trigger the camera to capture an image of the person attempting the associated fraudulent transaction, to record transaction information, and to trigger an alarm for immediate response.
