AUTOMATED TELLER MACHINE WITH FRAUD DETECTION SYSTEM

摘要

One embodiment involves a method for detecting fraud occurring at an Automatic Teller Machine ("ATM"). The ATM may include at least one cassette holding a denomination of paper currency to dispense. In one step, an ATM network host computer system receives a communications signal from the ATM. The signal comprises a transaction request to withdraw funds from the ATM by a user of the ATM. The communications signal also includes a transaction denomination value for the cassette holding the paper currency to dispense. The ATM network host computer system evaluates whether the transaction denomination value is different from an expected denomination value for the cassette. The transaction request is flagged if the transaction denomination value is different from the expected denomination value.
