Patent attributes
A system for detecting a fraudulent ATM transaction is disclosed. The system relates to an ATM machine that receives a bank/ATM card from a customer. The ATM first attempts to read information from the card chip, but is unable to do so due to a read error. The ATM then instead reads the information from the magnetic strip, and initiates a fraud detection procedure. In one such procedure, the ATM uses a local wireless access point to detect a customer's device, such as a phone, in the vicinity of the ATM. In another such procedure, the ATM communicates with a backend server. The backend server then determines the location of the customer device either by transmitting a message to request authorization, or by utilizing GPS or other location-detection means on the customer device to determine whether the customer device is within the ATM vicinity.
