Patent attributes
Proposed are a highly reliable automatic transaction device and a control method thereof. Specifically provided is an automatic transaction device, and a control method thereof, including a main body control unit which generates first withdraw transaction data including amount information as information related to an amount in a withdraw transaction and a withdraw command for instructing a withdraw of a paper currency based on the first withdraw transaction data, a paper currency processing unit which receives the withdraw command and pays out the paper currency, and a first device which is a device that is different from the paper currency processing unit and which determines a feasibility of a withdraw based on the first withdraw transaction data sent from the main body control unit. When the first device determines that the withdraw is possible, the first device generates withdraw credit information with security that is higher than the withdraw command based on the first withdraw transaction data. The paper currency processing unit receives the withdraw credit information and the withdraw command, additionally determines the feasibility of the withdraw based on the withdraw credit information and the withdraw command, and pays out the paper currency when the withdraw is possible.
