Description

The present invention relates to a contactless IC card and a ticket gate system using a mobile phone terminal that also functions as an electronic commuter pass among mobile phone terminals having an IC card function.

  In recent years, various commercializations are planned in various industries for the purpose of full-scale spread of IC cards. For example, it is an electronic ticket (IC commuter pass) scheduled by JR East. These IC cards are non-contact type IC cards in terms of reliability and application.

  Non-contact type IC cards are classified into “contact type”, “proximity type”, and “neighboring type” according to communication distance and method (usage frequency, etc.), and the international standards ISO / IEC10536, ISO / Standardization is underway as IEC14443 and ISO / IEC15693. For example, the maximum communication distance with the “contact type” reader device is about 2 mm. Similarly, the “proximity type” is about 10 cm and the “neighbor type” is about 70 cm.

  In general, a non-contact type IC card has a business card size and does not have a power source. Therefore, power for operating the IC card is supplied by electromagnetic waves from the reader / writer device.

  Normally, information is input to and output from an IC card through a reader / writer device.

  As shown above, an IC card usually does not have a power supply, and is supplied with power for operating the IC by electromagnetic waves from a reader / writer device installed in the ticket gate system, and is also defined by the Radio Law. There is a disadvantage that the communication distance is shortened when trying to use the power.

  Further, since the IC card does not have a display function, when viewing information data recorded on the IC card, there is a disadvantage that the reader / writer device must be separately provided.

  Furthermore, when information on electronic commuter passes is held, it is necessary to perform the information via a reader / writer device each time information data such as deposit is input, which is inconvenient.
