Information processing device, display switching method and program

A display switching method comprising the steps of:

• reading information of one or more than one electronic ticket stored in an IC card by a reading unit;
• determining whether the information of the electronic ticket corresponding to service identification information for identifying a service related to an electronic ticket stored in an information processing device matches the information of one or more than one electronic ticket read by the reading unit;
• supplying light from a light emitting unit to an operating means mounted on the IC card and capable of switching display contents on a display unit of the IC card by a potential difference occurring due to photoelectric conversion;
• and
• displaying the information of the electronic ticket corresponding to the service identification information on the IC card by the number of times of emitting light or the light emitting pattern of the light emitting unit adjusted based on a result of the determination.

A program causing a computer controlling an information processing device including a light emitting unit to supply light to an operating means mounted on an IC card and capable of switching display contents on a display unit of the IC card by a potential difference occurring due to photoelectric conversion to function as an information processing device comprising:

• a light emission adjusting unit to cause information of an electronic ticket recorded on the IC card to be displayed on a display unit of the IC card by adjusting the number of times of emitting light or a light emitting pattern by the light emitting unit;
• a storage unit to store service identification information for identifying a service related to an electronic ticket;
• and
• a reading unit to read information of one or more than one electronic ticket stored in the IC card,
• wherein
• the light emission adjusting unit adjusts the number of times of emitting light or the light emitting pattern by the light emitting unit so as to switch display on a display screen of the IC card to the information of the electronic ticket corresponding to the service identification information.
