Abstract:
[Problem] A system is provided that helps to prevent unauthorized use of an information code displayed on a screen. [Solution] In this system, when a first rule is received from a server (40) in response to a first request to the server (40), an information code display device (20) cyclically displays a plurality of partial code images on the display screen of a display unit (24) on the basis of the first rule.
