  • Patent number: 12020546
    Abstract: 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.
