<p>The present invention prevents counterfeit tests using automatic transaction machines. When a user cancels a transaction associated with a deposit at an automatic transaction machine, information on the account for which the transaction is intended is sent to a host computer. When the deposited bills is rejected at a high rate, the account information is sent to the host computer. Because these acts often occur during counterfeit tests, the host computer stores the account in a monitoring database, and monitors the cancellation frequency, rate of rejection, and the like. Accounts which are determined to have a high possibility of being used for counterfeit tests based on results such as cancellation frequency are handled as accounts requiring special attention. When a transaction takes place for an account requiring special attention, measures that can be taken including stopping the transaction or transmitting a warning. In this way, counterfeit tests can be monitored and prevented. <IMAGE></p> |
