Abstract

PURPOSE:To decide a storage and an erasing according to the decision of a user by providing an IC card processor having a display means for displaying the contents stored in a transaction hystory storing area and an erasing means for erasing an arbitrary transaction hystory from the transaction hystory storing area. CONSTITUTION:The amount of money of the amount of money storing area M2 which can be used by the IC card 1 is subtracted at every transaction by the IC card 1 and the transaction hystory is stored in the transaction hystory storing area M3. The number of the cases of the transaction which can be stored in the transaction hystory storing area M3 fills, and then, this IC card 1 is connected to the IC card processor. The IC card processor displays the transaction hystory stored in the IC card 1 by the display means, recognizes the transaction hystory according to this display and the unnecessary transaction hystory is erased by the erasing means. Thereby, a free area is formed in the transaction hystory storing area M3 to store the hystories of the transaction thereafter. Namely, an old and important transaction hystories can be left.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an IC card transaction system for processing transactions using IC card data, and more particularly to a method for erasing transaction history data stored in an IC card.

(b) Summary of the Invention The IC card transaction system according to the present invention includes an IC card processing device that can display a plurality of transaction histories stored in an IC card and erase any one of them. This allows you to keep only the necessary transaction history.
This enables effective use of the transaction history storage area by erasing unnecessary transaction history.

(e) Prior Art Conventionally, an IC card transaction system has been proposed that uses an IC card to process transactions. area, and a transaction history storage area for storing the history of transactions using this IC card. The amount stored in the usable amount storage area is subtracted by the amount corresponding to the price each time it is used, and the result of the transaction is stored in the transaction history storage area.

The transaction history storage area is generally set to 100 areas, and can store 100 transaction histories. IC
When there are more than 100 card transactions, conventional IC cards use a circular storage system that erases the oldest transaction history from the existing transaction history and stores the new transaction history. was.

(Problem that the d1 invention aims to solve)However, with such a circular storage system, even if the transaction history is important and should be kept for a long time, it will be difficult to keep track of 100 transactions after that transaction. If a transaction was made, the transaction history would inevitably be deleted.Also, some transactions are of low importance, and it would be safe to delete the transaction history of such transactions at an early stage. there were.

In other words, with conventional IC cards, it is not possible to change the timing of erasing transaction history depending on the importance of such transactions.
There was a problem in that it was not possible for the user to decide whether to save or delete the data.

In view of such conventional problems, the present invention has made it possible to delete any transaction history among the stored transaction history in advance and store the transaction history of later transactions in the erased area. The purpose is to provide an IC card transaction system.

(e) Means for Solving the Problems The present invention provides an IC card having a usable amount storage area for storing a transactable amount and a transaction history storage area for storing a plurality of transaction histories. In a system having an IC card that communicates with a transaction processing device and makes payment within the range of the available amount, the system includes a display means for displaying the contents stored in the transaction history storage area and any transaction history for displaying the transaction history. (f) Operation The IC card transaction system of the present invention operates as follows. For each transaction using the IC card, the amount in the usable amount storage area of the IC card is subtracted, and the transaction history is stored in the transaction history storage area. When the number of transactions that can be stored in the transaction history storage area becomes full, this IC card is connected to an IC card processing device. The IC card processing device displays the transaction history stored in the IC card using the display means. The transaction history is confirmed by this display, and unnecessary transaction history is erased by the erasing means. This creates an empty area in the transaction history storage area, allowing future transaction history to be stored. In other words, it is possible to keep the transaction history of important transactions even if they are old.

The balance of the available amount is stored in (usable amount storage area). Furthermore, area M3 is a transaction history storage area that stores transaction history such as shopping for products, and stores the name of the store where the transaction was made, payment amount, etc. There are 10 in this area
It is possible to store 0 transaction history, and when the transaction history exceeds 100 without being erased, the data is rewritten starting from the oldest data.

FIG. 5 is a flowchart showing the transaction history deletion operation of the ATM, and FIGS. 6(A) and (B) show the CR at that time.
A display example of P25 is shown. With reference to these, the ATM
The transaction history deletion operation in step 2 will be explained.

When this ATM is on standby, the screen shown in FIG. 6(A) is displayed on the CRT 25. At the bottom of the screen, function keys are displayed that indicate the details of each transaction and process.

When the IC card processing key 25a is pressed in this state, the process proceeds to steps nl (hereinafter referred to as ni) and steps n2 to 03 in FIG. At n3, the insertion of the IC card is accepted, and data such as transaction history is read by communicating with the inserted IC card (n4). When the data reading is completed, the transaction history is displayed on the CRT 25.

An example of the display screen at this time is shown in FIG. 6(B). The various function keys displayed at the bottom of the screen are the erase key, which erases the transaction history at the cursor position, and the display change key (next line key), which changes the transaction history displayed on the screen or moves the cursor. , previous page key, next page key, previous page key) and an end key to finish this work. The horizontal line on the transaction history display screen is a cursor, and the letter D indicates the deleted transaction history. n6. At steps n7 and n8, the process waits until the respective function keys are pressed, and when the display change key is pressed, the process proceeds to n9 based on the judgment at n6, the corresponding display change is performed, and then the process returns to the standby routine.

Also, when the erase key is pressed, nlo is determined by n7.
After proceeding to the following operations and setting the deletion flag provided for each transaction history (n10), the letter D is displayed on the screen (nil) and the process returns to the standby routine. Note that the letter D on the screen (corresponding display memory area) may be used as the deletion flag. Also, when the end key is pressed, n
Based on the judgment in step 8, the process proceeds to operations n12 and below.

At n12, the total transaction amount of the erased transaction history is calculated and stored in the transaction history storage area as one transaction history.

After this, the transaction history storage area that stored the deleted transaction history is compressed to compress the data (n13), and this data is written to the transaction history storage area of the IC card (n13).
