Description

  The present invention relates to a communication system, a communication method, and a program, and more particularly to a communication system, a communication method, and a program that enable short-range wireless communication between communication apparatuses to transmit and receive applications.

  A portable terminal and a communication system that provide an application service to a user by performing non-contact communication with a nearby fixed / installed terminal (reader / writer) using a near field communication (NFC) protocol, etc. Is provided. For example, an electronic money system or a commuter pass that performs payment processing by mounting non-contact communication with an electronic money terminal installed in a store by installing electronic money and its application on a portable terminal capable of non-contact communication・ Entrance / exit where information such as membership cards / tickets and their applications are installed in a portable terminal capable of non-contact communication, and the gate is opened and closed by communicating with a fixed terminal located at the ticket gate / check gate Management systems are widely used.

In this type of system, the fixed / installation type terminal does not support the application installed on the mobile terminal, the application installed on the mobile terminal cannot be used, and the service cannot be used. For example, regional money that can be used for a certain period in a certain area is installed in a mobile terminal, but a fixed terminal installed in a store that the user wishes to use may not support this regional money.
In such a case, the regional money installed in the portable terminal cannot be used, the regional money is not spread, and there is a possibility that the store terminal side loses the business opportunity. In order to process regional money, it is necessary to install an application corresponding to the fixed terminal side. However, real-time correspondence is usually difficult.

  Patent Document 1 describes an electronic money terminal that can handle a plurality of types of electronic money. Specifically, in Patent Document 1, for example, an application of electronic money mounted on an IC card that can communicate with an electronic money terminal installed in a store does not correspond to an application mounted on the electronic money terminal. In this case, it is described that an application is transmitted from the electronic money terminal to the IC card, and the IC card newly stores the application.

  Patent Document 2 discloses a system that facilitates contactless payment transactions across different contactless payment systems using a common portable device that functions as a value storage device, and is carried by a payment system of a member store apparatus. A system is described that enables the payment system on the mobile device side to be used by emulating it in a standard or the like used in a different payment system when the device is not compatible.
