Abstract
A two-dimensional code display system has a display unit which can display a two-dimensional code representing predetermined information by plural cells arrange in a matrix, and a control unit which changes the display form of the two-dimensional code. For example, after 0.5 second has elapsed since the display unit starts displaying the image of a logo mark, the control unit controls the display unit to change the display from the image of the logo mark to a two-dimensional code. After 2.0 seconds has elapsed since the display unit starts displaying the two-dimensional code, the control unit controls the display unit to change the display from the two-dimensional code to the image of the logo mark. By repeating such control, the control unit can control the display unit to display alternately the image of the logo mark and the two-dimensional code.
