Abstract

PURPOSE:To improve the operability by operating a specific key so as to re- input the data when transaction data is updated and it is not necessary to change the transaction data inputted once. CONSTITUTION:When a fixed information mark (*) is not given but an already inputted data exists, the already inputted data is displayed. When the operator agrees with the operation, the operator depresses a key with * mark. The key is included in input keys 7 of an IC card holder. When it is discriminated that the * key is depressed, the data is preserved and the processing corresponding to the next operating procedure is given. When the key is not the * key, the data inputted newly by keys are stored in a transaction data storage area corresponding to the operating procedure designated by the pointer at present as they are and the processing corresponding to the next operating procedure is given after the enter key is depressed.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field The present invention relates to an IC card transaction system that allows transactions to be carried out using an IC card.

(b1 Background of the invention IC cards with an IC embedded inside them have the potential to become widespread in the future as intelligent cards that have processing capabilities themselves. Cards with striped sides)
The major difference is that the IC card itself has intelligent functions and can have a very large storage capacity.

(0) Purpose of the Invention The purpose of the present invention is to utilize the characteristics of the IC card as described above to enable the IC card to memorize the operating procedures of the transaction processing device itself, and to enable the IC card to memorize the operating procedures of the transaction processing device, and to enable the IC card to store the operating procedures of the transaction processing device, Another object of the present invention is to provide an IC card transaction system in which once input transaction data does not need to be changed, the data can be re-inputted by operating a specific key without having to input the data again.

(d1 Structure and effect of the invention In summary, this invention provides an operation procedure table for storing the operation procedures of an ATM, etc. and transaction data that can be written by accessing from an external data input device in an IC card, and furthermore, this table When a specific key is operated while the table is being accessed from an external input device to update the contents of the table, a single stage is provided that retains the data specified by that specific key. do.

With this configuration, according to the present invention, I
When updating the transaction data in the operation procedure table stored in the C card, there is no need to re-enter the same data that does not need to be changed among the already stored data, improving operability. There are advantages to doing so.

For example, if you enter the transaction amount at the beginning and enter the PIN number just before the transaction, it will be easier to perform the operation immediately before the transaction, but if you
Even if the IC card is lost, the possibility of unauthorized use because the password number has not yet been entered can be almost eliminated. That is, when there is a plurality of transaction data, by changing the input timing of the data, it is possible to maintain security while improving operability.

The banknote deposit/withdrawal control unit 16 controls the deposit of banknotes inserted into the banknote insertion slot 28 and controls the withdrawal of banknotes to the banknote discharge port 29 . Line control section 17
controls transmission between the center and the center that has large-capacity data files.

FIG. 1 is a partial configuration diagram of the ROM 21 in which the IC 2 resides. BF constitutes an input data buffer. The input data includes, for example, a transaction type and a bank number. In the example shown in the figure, input data in which the transaction type is 1 and the bank number is 1234 are stored. Area IM constitutes a bank operation procedure table index. 1234,2345.
Each serial number of 3456 is a bank number. In the case where the bank number is 1234, the first address where each procedure is stored is stored in order so that steps 11, 21, and 3 are executed respectively. Similarly, if the bank number is 3456, the first address of the area for storing steps 6 and 7 is sequentially stored. Area MA constitutes an operation procedure table that stores operation procedures and transaction data for the transaction processing device. The operating procedures are stored in order from step 1, and the start address of each procedure is stored in the table index IM in correspondence with the bank number as described above. a w i is the operating procedure, and A-C is the transaction data. Transaction data A-C can be written in the card holder described above. Also, the aNi procedure is automatically written from the center via ATM. Writing of transaction data is performed under the control of the IC card itself, as will be described later. In the illustrated example, transaction data corresponding to the operating procedure d, "Press the code" and the operating procedure e, "Press the amount" are not stored. Also, the transaction data corresponding to step f "Press transfer destination" is 1234567, but this transaction data is added to the operation procedure storage column *
(Fixed information mark) indicates that the information is fixed information.

FIGS. 8(A) and 8(B) are flowcharts showing the operation of the IC card.

When the IC card 1 is inserted into the card holder main body 6 or the ATM card reader 2 and a start command is input from the key 7 or 25, the step nl (step ni
is simply called ni) and proceeds to n2. The input data is passed as is to the IC card, and the IC card determines whether the input data is from the ATV or the card holder. Note that since the IDNI of the ATM or card holder is added to the input data, the IC card knows which type of input data it is by checking this IDNa.

If the input data is data from the card holder, the process proceeds from n2 to n3. After n3, transaction data is set from the key 7 of the card holder to the operation procedure table MA. First, at n4, data on the transaction type and bank number are entered into the buffer BP, and after waiting for the enter key to be pressed, the process proceeds from n5 to n6. In n6, based on the data input to the buffer (a predetermined address in the operation procedure table is set to the pointer. For example, as shown in FIG. 1, if 11234 is input to the buffer BF, the pointer is set to The address where "Press the code" is stored is set.Next, at n7, the contents of the operation procedure for the address specified with the pointer are displayed, and at n8, a fixed information mark (*) is added to the operation procedure. In addition, it is determined in n9 whether the transaction data corresponding to the operation procedure specified by the pointer has already been input.If the fixed information mark has been added, n1
Step 7 advances the pointer by one and updates the operation procedure table address. That is, in the above example, the address set in the pointer is the address of the area where "Press amount" is stored.

The contents of the address specified by the pointer in n18 are END.
”, and if not, execute the steps from n7 onwards again. If it is “END”, it ends at that point. Also, if there is no fixed information mark in n8 and n9 and there is no input data, In this case, the key manual data should be stored as is in the transaction data storage area corresponding to the operation procedure currently specified by the pointer.
15), wait for the enter key to be pressed (n16)
Proceed to n17.

[Detailed description of the invention]

Also n8. In n9, if there is no fixed information mark but there is input data, the process advances to nto and the input data that has already been input is displayed. At this point, the operator is asked whether the entered data is OK. If the operator determines that it is acceptable, the operator presses the key marked with *. This key is included in the input key 7 of the IC card holder. This key corresponds to a specific key of the present invention. If it is determined in n12 that the * key has been pressed, the process advances to n17 to proceed to processing for the next operating procedure. *If it is not a key, the process advances to n13, and the newly input data is stored replacing the input data displayed in nlo. Thereafter, steps n14 to n16 described above are executed, and the data from the input key is stored at the same address until 1 when the enter key is operated, and when the enter key is operated, the process proceeds to n7.

In the manner described above, desired transaction data can be written into the transaction data storage area without the fixed information mark. Furthermore, if the input data has already been stored, the data can be saved simply by operating the * key.

Incidentally, in the above n7 and nlO, it is not the IC card but the display 8 of the card holder that displays the data.

The IC card only sends its display data to the card holder.

[Explanation of operations other than characteristic parts]

Next, the flowchart shown in FIG. 8(B) will be explained. If the data input at n1 is the input data from the ATM, the process proceeds from n2 to f120, as shown in Fig. 8 (B
) Execute the flowchart shown in ). First, the transaction type and bank number data are input from the ATM side (n20), and the transaction type and bank number data are set in a predetermined area (n21).Next, in n22, the bank number is the one-line operation procedure table index. Determine whether it is in IM. If there is, execute n23 and subsequent steps; if not, terminate.

At n23, the start address of the first procedure of the procedure group stored in the index IM corresponding to the bank number is searched from the operation procedure table MA. Transaction type data is assigned to each procedure (in the example shown in FIG. 1, procedures 1 to 7). In n24, the transaction type data is A
Send to TV. For example, if the transaction type data of procedure 1 is 1 and the procedure searched at n23 is procedure 1, then the transaction type data transmitted to the ATM at n24 is 1. Subsequently, in r125, the address of the operation procedure table MA is set in the pointer. That is, the start address of the searched procedure is set in the pointer. At n26, transaction data corresponding to the operating procedure set in the pointer at that time is transmitted to the ATM. For example, if the pointer is set to the address of the operation procedure "Press the code" at the start address of procedure 1, data 1234 is transmitted. In step n27, it is determined whether the transaction data has a fixed information mark. Otherwise, erase the input data sent by n2B. This is done to increase the security of transaction data. If the data has a fixed information mark attached, the process proceeds to n29 without erasing the data, and the pointer is updated to the address of the next operating procedure. At n30, it is determined whether the operation procedure is END, and if not, the process goes to n26 again and the transaction data is transmitted to the ATM.

When the operation procedure reaches END, proceed to n40.

At n40, the next data input is waited, and at n41 it is determined whether the input data is an operation procedure load request sent from the center via the ATM. Otherwise, exit. If it is an operation procedure load request, the process advances to n42 and executes processing for storing the operation procedure sent from the ATM side in table MA. It is determined at n43 whether the first sent move is already memorized. In the example shown in FIG. 1, steps from move I@1 to step 7 have already been stored, so any other steps are considered new steps and the process proceeds to n44. Note that the determination as to whether the procedure is a new one is made by determining whether the transaction type data is new. If it is a new procedure, n4
In step 4, a new address of the operation procedure table MA is set in the pointer, and the data sent in n46 is stored in n4B. The data sent here is data indicating an operating procedure, and is the operating procedure data stored in areas a to 1 shown in FIG. Note that the starting address of the new procedure storage area is stored in the area of the table index IM corresponding to the bank currently receiving service. Steps n46 to n48 are repeated until the input data becomes ETX (data indicating the end), and the process ends when ETX is input. Also, if there is already a procedure failure in n43 above, n45
Proceed to and set the start address of the existing step in the pointer. Next, the data sent continuously from n46 to n48 until ETX is sent.
Store 1°. That is, in this operation, the procedure cannot be updated.

Although a card holder was used as an external data input device in this embodiment, it is also possible to use a computer or other data input device.
