  In order to solve such problems, it has been studied to provide a mobile phone with a reader / writer function for a non-contact IC card (for example, Patent Document 1), and in fact, a non-contact of FeliCa (registered trademark). In IC chips, contactless IC chips that can operate as reader / writer functions for contactless IC cards have also been developed, but they have a reader / writer function for contactless IC cards and an electronic money function. A mobile phone that functions as an IC card viewer for contactless IC cards has not been developed.

  In addition, unlike cash, electronic money can only be used at member stores, so not only the balance function of electronic money but also the stores where electronic money can be used using the Internet connection function provided for general-purpose mobile phones. Although it is desirable to be able to provide data to the user, a system that allows the user to search for a store corresponding to the use history of a contactless IC card having a function of electronic money has not been disclosed.

  For example, Patent Document 2 and Patent Document 3 are disclosed as inventions for retrieving store data using a mobile phone, but the invention disclosed in Patent Document 2 groups stores by genre. A system in which channels are prepared in advance and stores that are grouped into channels corresponding to the genre selected by the user are introduced. The invention disclosed in Patent Literature 3 describes the position of a mobile phone acquired by GPS. It is a system that introduces stores in the vicinity.
