Abstract
A display device includes a display, an acquirer, and a controller. The display is configured to display a display image containing identification information of a purchase item to a reader of a cash register. The acquirer is configured to acquire external output information from the cash register. The controller is configured to control a display operation of the display on the basis of the external output information. When the controller determines, on the basis of external output information of a first purchase item from the cash register, that the cash register has identified the first purchase item, the controller causes the display to display a display image containing identification information of a second purchase item.
