DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an IC card for reservation transactions that can store and process transaction information including reservation transactions.

[Technical background of the invention and its problems] An IC card for reservation transactions, which has an integrated circuit chip such as a microprocessor or memory embedded in a thin plastic card the size of a credit card, is convenient to carry and can store various information. Since it can store information and has a relatively large storage capacity, it is being used for various purposes, one of which is electronic money cards.

An electronic money card can be used to purchase goods and to make payments using the card. When using such a card, in addition to purchasing goods directly and making a payment, there are cases where a reservation purchase is made. When making a reservation purchase, etc., you make the reservation and then make decisions such as receiving the goods and paying the amount later. In some cases, reservations may be canceled.

To explain in more detail, there are things that can be pre-purchased, such as airline tickets, theater admission tickets, train rides, and reserved tickets. Even if you later decide that you no longer need the reservation ticket for some reason and cancel it, the problem with conventional electronic money cards using IC cards is that you cannot get the reservation amount back in response to this cancellation. was there.

One proposed solution to this problem is to perform all the above-mentioned cancellation processing in a central computer to which the IC card is connected, and then send it back to the IC card. In this case, there is a problem that the load on the central computer increases and the central computer cannot perform sufficient processing.

[Object of the Invention] This invention has been made in view of the above, and its purpose is to provide a reservation transaction system that can easily process reservation transactions, including cancellation processing, using a simple configuration on the IC card side.

In addition, the transaction code 47 is composed of 7 bits as shown in the partially extracted part, and the least significant bit (LSB) is 7 bits.
) constitutes the reservation code 59. When a reservation transaction is performed, "1" is stored in the reservation code 59, and when a transaction is performed thereafter, the "1" stored in the reservation code 59 is erased.

Next, the effect will be explained.

First, the case of a reservation transaction will be explained. FIG. 5 is a diagram showing the connection and information exchange between the IC card 21, the terminal device, and the center computer when performing a reservation transaction, and FIG. is a flowchart showing the flow of processing operations in case of reservation transaction.

In both figures, when the IC card 21 is first inserted into a terminal device that is a card reader/writer (step 110; the step numbers used in the following explanation are for FIG. 6), the IC card 21 is inserted from the terminal device. Power and clock are supplied to the device, the reset signal is released, the IC card 21 is activated (step 120), and the IC card 21 sends an answer signal (ANSWER) in response to the reset signal back to the terminal device. Ru. Here, it is checked whether the IC card 21 is a normal card (step 130), and if it is normal, PIN information is input.

Check the P[J information and if it is correct, press the call key to capture the communication network for the computer, automatically dial the communication network to call the computer, and establish a connection with the computer (Steps 140- 180).

When the connection with the computer is completed, the communication password stored in the communication password storage frI area 33 and the card number stored in the card number/name storage area 31 are transmitted to the computer via the terminal device. , receive a response from the computer (steps 190.200
).

If the response result from the computer is correct, guidance is received from the computer (step 210.22).
0>. Then, input the reservation data from the key switch,
In response to this, the reservation reception data from the computer is received, and the reservation data is written to the IC card 21, guidance is displayed, and the completion of writing is transmitted to the computer (step 230).
~260). In addition, in writing this reservation data, the reservation data is stored in three transaction information storage areas of the memory 25 of the IC card 21 according to the transaction data format, and "1" indicating a reservation is stored in the reservation code 59. This allows it to be determined that there is a reservation transaction. As a result, it is now possible to completely handle settlements after reservation transactions, such as delivery of actual goods and amounts, or cancellation.

When the writing completion information is sent to the computer 11, a new communication password sent from the computer is received, and this communication password is stored in the communication password storage area 33 of the memory 25 of the IC card 21 (steps 265 and 270).

When this write completion information is sent to the computer, the completion information is received from the computer (step 280.29).
0>. As a result, the power supply to the IC card 21 is stopped, the IC card 21 is reset, and the IC card 21 is ejected from the terminal device, thereby completing the processing for the reservation transaction (steps 300 and 310).

Incidentally, in steps 130, 150, and 210, if the IC card 21 is not normal, the IC card 21 is ejected from the terminal device and the procedure cannot be performed.

Next, when a reservation transaction is approved and a normal transaction is performed, that is, the issuance process of receiving and receiving a product reserved in the aforementioned reservation transaction, such as a ticket such as an airline ticket, is shown in Figures 7 and 8.
This will be explained with reference to the figures.

FIG. 7 is a diagram showing the exchange of information with a terminal device such as the IC card 21, and FIG. 8 is a flowchart showing the operation of the issuing process for making a settlement after the reservation transaction.

In both figures, first, the IC card 21 is inserted into the terminal device (step 410 (the step numbers used in the following explanation are for FIG. 8)), and the terminal device supplies the power and clock to the IC card 21. At the same time, the reset signal is released and the IC card 21 is activated (step 420).
SWER> is sent back to the terminal device. Here, it is checked whether the IC card 21 is a normal card (step 430), and if it is normal, the PIN information is input, and if the PIN information is verified and is correct, the reservation display key is pressed. Step 440 to read the reservation data from the transaction information storage area 39 of the memory 25 of the IC card 21 and display the read reservation data on the display.
480〉. Next, the ticketing key for issuing a reservation number and a ticket such as an airline ticket is pressed, the reservation number, date, and ticketing command are transmitted to the IC card 21, and a response from the IC card 21 is received (step 490). ~510). At this time, since the actual transaction for the reserved transaction is performed, the "1" stored in the reservation code 59 of the transaction information storage area 39 is erased, and the reserved transaction is changed to a normal transaction. When the process is completed above, the actual ticket issuing process is performed, the process ends, and the IC card 21 is ejected (
Steps 520, 530). Note that for ticket issuing processing, the ticket issuing data is later batch-processed by the center computer. Further, if the IC card 21 is found not to be normal in steps 430, 450, and 520, the IC card 21 is released and the procedure is stopped.

It should be noted that almost the same process is performed when a reservation transaction is canceled, that is, a reset is performed, and the five "1"s in the reservation code are similarly deleted and the reservation is canceled.

[Effects of the Invention] As explained above, according to the present invention, the reserved transaction information regarding the reserved transaction is stored, and when the reserved transaction is canceled, the reserved transaction information is deleted on the IC card side. , even if the reservation transaction is cancelled, the reservation amount can be processed normally without any problem, and since the processing is done only on the IC card side without using the functions of the center computer, etc., the center There is no increase in the load on the computer, and there is no need for communication costs with the center computer, making it more economical.
