Patent ID: 7152230

Claim:
A smart card system for managing an initial issuance and a re-issuance of an IC card comprising a data processing unit in an integrated circuit, a memory, and a terminal connected to a network, comprising: a smart card issuance system configured to perform issuance and management of a smart card; and a smart card service providing system configured to perform issuance and management of an application loaded on the smart card, wherein the smart card issuance system and the smart card service providing system are operatively connected to each other through a network such that information exchange is achieved by transmitting and receiving electronic messages through the network. each of the electronic messages, which is exchanged between the smart card issuance system and smart card service providing system, is uniquely identified using a message ID, data of the smart card issuance system and the smart card service providing system is stored using the message ID as a key, and the information exchange between the smart card issuance system and the smart card service providing system includes communication through the network connections wherein at the time of initial issuance of the smart card, the smart card issuance system sends an application loading permission to the smart card service providing system to permit loading an application into the smart card through a terminal, at the time of the initial issuance of the smart card, the smart card service providing system sends the application loading permission and the application to the smart card and loads the application into the smart card through the terminal, and at the time of the reissuance of the smart card, the smart card service providing system receives card attribute data from the smart card, which can be identified only by the card issuer, sends the card attribute data and an application ID of the application to the smart card issuance system, the smart card issuance system searches the message ID which was used when the smart card issuance system sent the application loading permission for loading the application to the smart card using the sent card attribute data, the card attribute data identifying the smart card service providing system, and sends the message ID to the smart card service providing system, the message ID having been used when the smart card issuance system sent the application loading permission for loading the application to the smart card, and the smart card service providing system searches an examination result of permission for loading the application at the time of initial loading application using the message ID as the key and loads the application into the smart card through the terminal based on the examination result of permission.
