A method of communication between a host of an automated teller machine and a device. The process is performed as a result of sensor polling which the host periodically performs to check a state of a device. The process is simplified by employing an interrupt communication scheme in which an interrupt signal for notifying that a change of a sensor value occurs in the device is transmitted from a device to a host. This simplification reduces USB traffic that occurs during a process of communication between the host of the automated teller machine and the device, thereby reducing a load that is applied to a communication hardware chip of the automated teller machine. As a result, the frequency with which a communication failure occurs is decreased, thereby achieving the effect of providing support for seamless communication.

The present disclosure relates to a worn banknote identification method and an ATM (Automated Teller Machine) using the same, and more particularly, to a worn banknote identification method which acquires an image of a banknote inserted into an ATM, divides pixels of the acquired banknote image into a bright region and dark region depending on a brightness distribution of the banknote image, determines the wear level of the banknote by comparing a difference between the average brightness values of the two regions to a preset reference value, and separately stores the inserted banknote into a reject box depending on the wear level of the banknote, and an ATM using the same.
