<p>Disclosed is a transportation card having a nationally-compatible function. According to the present invention, the transportation card comprises a card operating system. The card operating system has a tree structure of a directory structure including a dedicated file (DF) and an element file (EF), wherein the dedicated file (DF) is added with an ADF which is called "Config DF" for the compatibility with each company so that the information on the compatible ADF for transportation is stored, and that the stored information is provided to the outside during transactions, and further the dedicated file includes an essential file capable of storing additional information that includes at least transfer information and entrance information. The card operating system recognizes the "Config DF" from a terminal, and performs payment transactions for an existing card on the basis of the recognized result after a nationally-compatible transportation card or the existing card is recognized, or performs payment transactions on a standard card for the nationally-compatible transportation card on the basis of the additional information. During the payment transactions on the existing card, the card operating system delivers keys of key transmission cards received from other electronic cash companies to an SAM for issuing a payment SAM, so that the SAM for issuing the payment SAM provides the keys to a payment SAM for the nationally-compatible transportation card whereby the existing keys issued from the payment SAM for the nationally-compatible transportation card and the keys for other electronic cash companies are issued en bloc. Therefore, the invention allows transportation cards to be compatible on a nationwide scale.</p> |
