The display unit displays a QR Code (registered trademark) (21), a Data Matrix (Data Code) (22), and an Aztec Code (23), all presenting the same information such as flight reservation details, for example, for 1.0 second each by turns. Consequently, there is no need of installing a two-dimensional code reader for QR Code (registered trademark), a two-dimensional code reader for Data Matrix (Data Code), and a two-dimensional code reader for Aztec Code and only any one of the two-dimensional code readers is necessary to read information such as flight reservation details. |
