DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a merchandise sales registration data processing apparatus for executing a registration process based on merchandise data to support sales operations.

[0002]

2. Description of the Related Art Electronic cash registers and POS (Point)
A merchandise sales registration data processing device such as a terminal (Of Sales) terminal supports a sales operation by executing a registration process based on merchandise data.

[0003] Such a merchandise sales registration data processing device is configured to close a registration process executed on the basis of input product data as a cash transaction or a credit transaction. The transaction statement data is generated based on the processing data. Here, the transaction details data is a series of data indicating the details of the transaction, and usually includes an identification number, a transaction date and time, a store name, a responsible name, a closing type, a large number of product data, a total price, and the like. For example, a receipt is issued by the R / J (Receipt / Journal) printer sequentially printing the transaction statement data generated in this manner on receipt paper.

Further, such a commodity sales registration data processing device sequentially adds sales numerical data including the number of sales of the registered commodity data and the sales amount, each time the registration processing is executed, and adds the sales numerical data to a RAM (Random Access Memory) or an HDD. (Hard Disk Dri
ve) and so on. Such a sales file is a product-specific sales file in which sales numerical data is classified and stored for each product, a department sales file in which sales numerical data is classified and stored in each department, and a sales numerical data is stored in cash. This is implemented as a transaction-specific sales file that is classified and stored for each payment method such as credit card and credit card, etc. This is included in a stand-alone type electronic cash register that does not communicate data with other devices, but is integrated with other devices. In a POS terminal or the like that performs data communication, it may be provided in a separate file processor or the like.

Therefore, in such a product sales registration data processing device, the sales file sequentially adds and accumulates sales numerical data including the number of sales and the sales amount of the registered product data, every time the registration process is executed. The sales numerical data is read out as desired and used for management of business conditions, planning of sales strategies, and the like.

Further, in such a merchandise sales registration data processing device, when a credit transaction is executed, transaction record data is generated. For example, the generated transaction record data is converted to a CAT (Credit Authorization).
Terminal) sends to the credit company via VAN (Value Added Network). Here, the transaction record data is a series of data indicating the contents of the credit transaction,
For example, the transaction details data is edited into a communication message with a credit company, and a communication message for a security check of the credit transaction is added thereto. Therefore, the credit company to which the transaction record data is transmitted from the merchandise sales registration data processing device executes a business such as billing a customer based on the transmitted transaction record data.

[0007] Here, in a store using such a merchandise sales registration data processing device, for example, a merchandise different from a customer's request is erroneously sold, or a defective merchandise is sold without notice. Something like that. Therefore, when the customer who has noticed the above brings the product for which exchange or return is requested and the receipt on which the product data of the product is printed to the store, the customer brings the product at this store. The exchange or return of goods is performed by visually checking the receipt.

In such a case, the clerk receives the receipt from the customer, subtracts the sales numerical data of the incorrect registration processing from the sales file by input operation of the keyboard, and re-writes the valid sales numerical data to the sales file as necessary. By inputting, the register minus process is executed.

Here, the transaction statement data printed on the receipt used by the clerk for data correction has contents in which a product name and a sales unit price are set for each department code of the product, and a settlement method, date and time, etc. are added. ing. Therefore, when executing the above-described cash register minus processing, the clerk inputs the payment method, the department code, the number of returned goods, and the return unit price actually printed on the receipt to the merchandise sales registration data processing device. The merchandise sales registration data processing device subtracts the input returned quantity and the returned unit price from the sales quantity and the sales amount, which are the sales numerical data stored in each division in the sales file for each division, which is the sales file. Alternatively, the transaction-specific sales file, which is a sales file, is subtracted from the sales quantity and sales amount, which are sales numerical data stored for each settlement method.

[0010] In the case of executing the credit transaction cancellation process by executing the above-described cash register minus process on the credit transaction, furthermore, the transaction cancellation data of the credit transaction is generated, and the credit company is created by a CAT or the like. To send to. Here, the transaction cancellation data is a communication message supporting the credit company to execute the cancellation process of the executed credit transaction. For example, the transaction cancellation data has a configuration in which the identification number of the credit transaction is added to the support data of the cancellation process. I have. Therefore, the credit company to which the transaction cancellation data is transmitted from such a commodity sales registration data processing device executes a business such as a charge request cancellation process based on the transmitted transaction cancellation data.

Although a standalone electronic cash register has been described as an example of the merchandise sales registration data processing device, a POS terminal in which a number of POS terminals are connected to a host device such as a host computer or a file processor is now described. A system or the like is also implemented as a merchandise sales registration data processing device.

[0012] In such a POS system,
Some POS terminals transmit sales numerical data to a higher-level device each time a registration process is performed. This higher-level device sequentially adds and stores sales numerical data as a sales file. Therefore, in a store office or a system headquarters where such a high-level device is installed, by reading out sales numerical data from a sales file as required,
It is possible to confirm the sales status and the like for each product, each department, and each settlement method.

In order to execute the cash register minus processing in such a POS system, the clerk inputs the settlement method, the department code, the sales quantity, and the sales unit price which are also printed on the receipt to the POS terminal.
A high-level device that performs data communication with the terminal modifies the sales numerical data in the divisional sales file and the transactional sales file.

[0014]

In the merchandise sales registration data processing device as described above, the register numerical processing is executed to correct the sales numerical data stored in the sales file properly. When a credit transaction cancellation process is executed as such a cash register minus process, transaction cancellation data is generated and transmitted, thereby favorably supporting the business of the credit company.

[0015] However, since many customers actually discard the receipt when they purchase the product, if such a customer requests replacement or return of the product, the customer often does not present the receipt to the store. is there. In such a case, it is difficult to confirm the fact that the customer purchased the product at this store, and it is difficult to deal with the exchange or return of the product.

In particular, if the credit transaction cancellation processing cannot be performed smoothly, not only the stores where the merchandise sales registration data processing device is installed, but also the operations of credit companies and banks will be confused.

[0017]

Means for Solving the Problems Data registration executing means for executing registration processing based on input product data is provided, and data closing execution means for executing the registration processing of the data registration executing means at least as a credit transaction is provided. And a statement data generating means for generating transaction statement data of a credit transaction based on the data processing of the data closing executing means and the data registration executing means, and detachably holding a portable data storage medium for customers. A medium data storage means for sequentially storing and accumulating transaction statement data generated by the statement data generation means in the data storage medium held by the medium holding means; Record data for generating transaction record data of a credit transaction based on the data processing of the data closing execution means. Record data transmitting means for transmitting transaction record data generated by the record data generating means to a credit company, and detailed data for reading specific transaction statement data from the data storage medium based on an input operation. Reading means; and cancel data generating means for generating credit cancellation transaction data of the transaction statement data read by the statement data reading means, and transmitting the transaction cancellation data generated by the cancellation data generating means to the credit company. Cancellation data transmission means, and confirmation data receiving means for receiving cancellation confirmation data from the credit company which transmitted the cancellation data by the cancellation data transmission means, wherein the confirmation data receiving means receives the cancellation confirmation data, the data storage medium A statement data update means for deleting the transaction statement data stored in It was.

[0018]

According to the present invention, credit transaction data is stored in a portable data storage medium for a customer, and is read out as required to execute a credit transaction cancellation process. By transmitting, the credit company's cancellation work etc. are favorably supported.

[0019]

And the like are configured by a predetermined storage area.

Here, as exemplified in FIG.
In the product data stored in the PLU table 32 of M11, for example, a product code is individually set for each of a large number of products to be sold, and for each product code, a department code, a product name, a sales unit price, a status, remarks, and the like. Is set.

The POS of the POS system 1
The computer 3 and the file processor 5 communicate with the R /
Except for not having the J printer 17 and the drawer unit 18, it has the same structure as the POS terminal 7, so the following description uses common terms and a detailed description is omitted.

In the POS system 1, FIG.
As shown in the example, in addition to the transaction-specific sales file 35 that classifies and stores sales numerical data for each transaction code, a product-specific sales file 38 that classifies and stores sales numerical data for each product code, The section-specific sales file 39 in which data is classified and stored for each section code is also configured as a sales file. Here, only the transaction-specific sales file 35 is provided in the RAM 11 of the POS terminal 7 as described above. The product-specific sales file 38 and the department-specific sales file 39 are stored in the file processor 5.
(Not shown).

The IC card 12 used in the POS system 1 is also a credit card, and as shown in FIG.
The POS terminal 7 includes an ID file 40 in which (Identification) data is set in advance, and a transaction statement file 41 that sequentially accumulates transaction statement data generated by the POS terminal 7. Therefore, in the ID file 40, a credit code, a customer name, an expiration date, and the like are fixedly set in advance, and the transaction statement data sequentially accumulated in the transaction statement file 41 includes a transaction date, a slip number, and a product number. It consists of a category, transaction category, transaction amount, tax / postage, handling category, payment start month, number of payments, etc. Since the storage capacity of such a transaction statement file 41 is necessarily limited,
Here, 99 records of transaction statement data can be stored, and when full, the oldest transaction statement data is overwritten with the latest transaction statement data.

Here, in the POS terminal 7 of the POS system 1, the RAM 11 is stored in the RAM 11 by the product code input from the touch scanner 14 or the keyboard 15.
The entire product data is read from the PLU table 32 and input to the CPU 9. As illustrated as a step P3 in a flowchart of FIG. The data registration executing means executes the registration processing based on the data. Further, as will be described later as Step P4, the data closing executing means performs the closing process as a cash transaction or a credit transaction as described later, and as described later as Steps P9 to P11, the data closing executing means and The recording data generating means generates sales numerical data based on the data processing of the data registration executing means.

In the POS system 1, a sales file for sequentially accumulating sales numerical data is referred to as P here.
The transaction-specific sales file 35 of the OS terminal 7 and the product-specific sales file 38 of the file processor 5
And the division-specific sales file 39, and as described later in step P12, the detailed data generation means determines the name and amount of the sales product based on the data processing of the data registration executing means and the data closing executing means. The transaction details data is generated, and the IC loaded in the card reader / writer 13 is described below as Step P13.
The medium data storage means sequentially stores and accumulates transaction statement data in the transaction statement file 41 of the card 12.

Further, in this POS system 1, a credit transaction may be executed as a sales operation, so that
As will be described later as Step P5, the closing determining means determines whether the transaction is a credit transaction or another transaction at the time of executing the closing process. As described later as Step P6, if this is a credit transaction, A record data generating unit generates transaction record data of a credit transaction based on data processing of the data registration executing unit and the data closing executing unit. Then, as will be described later as step P7, the record data transmitting means transmits the transaction record data to the credit company, and as described later as step P8, when the return receiving means receives the transaction confirmation data from the credit company, the sales numerical value is obtained. It starts to generate data.

The POS terminal 7 of the POS system 1 executes a cash register minus process when a customer requests a return or exchange of a product. By executing also in the case of, the cancellation processing of the credit transaction is also executed. Therefore, when such a credit transaction cancellation process is executed, the following FIG.
As exemplified in steps S1 to S7 in the flowcharts of 0 and 11, the statement data reading means reads specific transaction statement data from the transaction statement file 41 of the IC card 12 based on an input operation. As will be described later as Steps S10 and S11, the read transaction statement data is format-edited by the data editing means, and the statement data display means is displayed and output.

Further, in the POS system 1, as will be described later as step S16, the cancellation data generating means generates the transaction cancellation data of the credit transaction based on the read transaction statement data. As will be described later, the cancellation data transmitting means transmits the transaction cancellation data to the credit company. Therefore, as described later as step S18, when the confirmation data receiving unit receives the cancellation confirmation data from the credit company in the above-described state, the process proceeds to step S1.
As will be described later as 9, S20, the statement data updating means deletes the transaction statement data of the transaction statement file 41 of the IC card 12.

Here, the cancellation confirmation data is a communication message transmitted by the credit company to the store for confirming the cancellation processing of the credit transaction. For example, the identification number of the credit company, the credit transaction, and the sales store Is added to the reply data of the cancellation confirmation. Also,
Deletion of the transaction statement data of the IC card 12 referred to here means not only initializing the transaction statement data, but also adding a deletion flag without initializing the transaction statement data. However, this does not only mean that data is actually erased.

Further, in the POS system 1, the numerical data generating means of the POS terminal 7 generates updated numerical data as described later as step S21, and as described later as steps S22 and S23. With the updated numerical data, the numerical data updating means of the POS terminal 7 and the file processor 5 also deletes the corresponding sales numerical data of the sales files 35, 38, 39.

The POS system 1 is basically based on the assumption that an IC card 12 carried by a customer is used. Therefore, data processing when a credit transaction is performed using the IC card 12 is illustrated. 9 will be described below in order based on the flowchart illustrated in FIG. 9, and the data processing in the case where the credit transaction cancellation processing is executed using the IC card 12 will be sequentially described below based on the flowchart illustrated in FIG. 10 to FIG. I do. Note that this P
The OS system 1 is, in fact, the same as the existing system.
Data processing such as cash transaction without using the C card 12 and cash register minus processing can be executed, and further, cash transaction and the like using the IC card 12 can be executed.

First, when the registration process is executed at the POS terminal 7 of the POS system 1, the operation mode of the CPU 9 is set to the registration mode by switching operation of the mode switch 21, and the input operation of the IC card key 30 is performed. Then, the start of the registration process using the IC card 12 is declared.

In this case, since the POS terminal 7 constantly monitors whether or not the IC card 12 is inserted into the card reader / writer 13 as shown in FIG. 9 (step P1), the POS terminal 7 desires to purchase a product. When the clerk inserts the IC card 12 received from the customer into the card reader / writer 13, first, data exchange is performed with the IC card 12 to obtain an access permission for a specific area as a security check. Upon acquisition, the ID data is read from the ID file 40 of the IC card 12 to determine whether it is appropriate or not (step P2). More specifically, a credit code, a customer name, and an expiration date are read out as ID data to check whether the credit code is appropriate and whether the expiration date has been exceeded, and the like, and the ID data is determined to be inappropriate. In this case, a message is displayed on the display 16 and error processing is executed.

Next, when the appropriateness of the ID data is determined as described above, the POS terminal 7 is in a state where the registration process can be executed. For example, the POS terminal 7 stores the P code in the RAM 11 with the product code input by the touch scanner 14 or the keyboard 15.
The product data is read from the LU table 32, the product data is stored in the work area 37, and the registration process is executed (step P3). When the above-described registration process is executed for all the sales products, the operation corresponds to the input operation of one of the closing keys selected from the deposit / current key 28 and the credit key 29 of the keyboard 15. The closing process is executed (step P4).

At this time, in the case of cash transaction, the closing process is executed by the deposit / current total key 28, and in the case of credit transaction, the closing process is executed by the credit key 29. The POS terminal 7 determines whether the closing process is a credit transaction or another transaction (step P5). If a credit transaction is detected in step P5, transaction record data is generated based on the product data temporarily stored in the work area 37 of the RAM 11, the ID data read from the IC card 12, and the like (step P6).
This transaction record data is transmitted to the credit company to receive transaction confirmation data (step P7). Here, the transaction confirmation data is a communication message indicating whether or not a credit transaction is possible, and has a configuration in which an identification number of a credit company, an IC card, or a store is added to response data indicating whether or not the transaction is possible.

Therefore, the POS terminal 7 judges whether or not the credit transaction is possible based on the received transaction confirmation data (step P8). If the POS terminal 7 judges that the credit transaction is not possible, a message is displayed on the display 16 and error processing is performed. Execute When the POS terminal 7 detects that the closing process is not a credit transaction in step P5, or determines that the credit transaction is possible in step P8, the POS terminal 7 stores the merchandise data temporarily stored in the work area 37 of the RAM 11. Summarize the sales unit price and store it in your own transaction-specific sales file 35,
The similar aggregation results are stored in the product-specific sales file 38 and the department-specific sales file 39 of the file processor 5 by data transmission, and the closing process is executed.

The POS terminal 7 that has completed the closing process in step P3 as described above generates sales numerical data including the sales quantity and sales amount of the product data registered in step P2, The sales code is classified and stored in the separate sales file 35 for each transaction code (steps P9 and P10), and the sales numerical data is converted into predetermined transmission data and transmitted to the file processor 5 (step P11). The file processor 5 receiving the transmission data in this way classifies and stores the sales numerical data restored from the transmission data in the product sales file 38 for each product code, and stores the sales numerical data in the department sales file 39 for each department code. And stored.

Then, the POS terminal 7 that has completed the data transmission in step P11 as described above generates transaction statement data by adding a store code to the registered product data (step P12), and generates the transaction details data in step P12. The obtained transaction statement data is stored in the transaction statement file 41 of the IC card 12 by the card reader / writer 13 (step P13). Therefore, the POS terminal 7 that has completed the data storage in step P13 is the card reader / writer 1
The IC card 12 is ejected from 3 (step P14), and in the case of a credit transaction, a credit slip (not shown) is issued by the CAT printer 19, and after such processing is completed, the process returns to the initial state.

As described above, the card reader / writer 13
When the clerk hands the IC card 12 and the credit slip discharged from the customer to the customer, the sales business for the customer is completed. At this time, such an IC card 12
Stores the transaction details data of the registration process,
For example, if the customer has a personal computer (not shown) for reading and displaying the transaction details data of the IC card 12, it is not necessary to issue a receipt (not shown) by the R / J printer 17. However, if the customer does not have such a device, it is desirable to issue a receipt in the same manner as in the past.

In the above-described manner, a store using the POS terminal 7 can execute a credit transaction or the like with high efficiency. May sell without notice. Therefore, when the customer who has noticed the above brings the merchandise and the IC card 12 to the store, the store exchanges or returns the merchandise and executes the credit transaction cancellation processing.

Therefore, the data processing of the POS system 1 for executing such a credit transaction cancellation process is shown in FIG.
0 to FIG. 12 will be sequentially described below. First, in the POS terminal 7, the credit transaction cancellation process is executed as a register minus process. First, the operation mode of the CPU 9 is set to the register minus mode by switching the mode switch 21, and the IC card key is set. Input operation of IC card 30 and IC card 1
Declares the start of cash register minus processing using credit transaction 2.

Then, as shown in FIG. 10, since the presence or absence of the insertion of the IC card 12 into the card reader / writer 13 is constantly monitored (step S1), the IC card 12 received from the customer who desires to purchase the product is received. Is inserted into the card reader / writer 13, after the security check is executed, the appropriateness of the ID data is confirmed (step S
2) After this confirmation, a continuation flag (not shown) in the flag area 36 of the RAM 11 indicating that the registration minus process is being continued is set to "ON" (step S3).

Next, the POS terminal 7 has a RAM
It is confirmed whether or not the continuation flag in the flag area 36 of No. 11 is "OFF" (step S4). If this is not confirmed, it means that the register minus process is continuing,
In such a case, a pull-down menu (not shown) is output and displayed on the display 16, and the process waits for an input operation of the search key serving as a search condition by the keyboard 15 (step S5). Therefore, the POS terminal 7 to which the search key has been input in step S5 retrieves the corresponding transaction statement data from the transaction statement file 41 of the IC card 12 based on the search key as illustrated in FIG. 11 and FIG. (Steps S6 and S7).

If no transaction data is detected in step P7, the POS terminal 7 displays a guidance message (not shown) on the display 16.
Is displayed to determine whether the search key has been changed by an input operation on the keyboard 15. If the search key is changed in this state, the process returns to step S2 (step S2).
8) If the search key is not changed in step S7, the continuation flag in the flag area 36 of the RAM 11 is set to "OFF" and the process returns to step S2 (step S9).

When transaction data corresponding to the search key is detected in step S7, the POS terminal 7 edits the read transaction data into a form suitable for display and printing (step S10). ), The transaction statement data edited in step S10 is displayed on the display 16, and the receipt is printed by the R / J printer 17 (step S11).

Therefore, the clerk presents the transaction details data displayed or printed in step S11 to the customer, and asks the customer to confirm whether the transaction details data is incorrect product data. When the customer accepts the transaction statement data, the clerk operates the keyboard 15
In this case, various data for executing the cash register minus processing of the transaction statement data is designated by the input operation of (1). If this input operation is not detected, the process proceeds to step S8 (step S12).

When the process returns from step S7 or step S12 to step S3 via only step S8 as described above, the POS terminal 7 sets the continuation flag of the RAM 11 as shown in FIG. Since "ON" remains, the above-described steps S4 to S12 and the like are restarted with the search key changed in step S8.

When the POS terminal 7 detects the specification of the transaction statement data in step S13,
As illustrated in FIG. 1, the confirmation flag of the designated transaction statement data is set to “ON” (step S13), and the RAM
11 after setting the continuation flag to "OFF".
4 (step S14). Therefore, when the process returns to step S4 from steps S8 and S14 in this way, as illustrated in step S4 in FIG.
Since the continuation flag of “11” is “OFF”, as shown in FIG. 12, it is determined whether or not the confirmation flag is “ON” in the transaction statement data of the transaction statement file 41 of the IC card 12 (step S15). Transaction cancellation data is generated based on the transaction statement data whose confirmation flag is “ON” and the ID data of the IC card 12 (step S16), and the transaction cancellation data is transmitted to the credit company (step S16).
17). Then, in this state, the POS terminal 7 waits to receive the cancellation confirmation data or the cancellation rejection data from the credit company (step S18). If the reception of the cancellation confirmation data is not confirmed, the display 1 is displayed.
In step 6, a message is displayed and output to execute error processing.

When the receipt of the cancellation confirmation data is confirmed in step S18, the POS terminal 7 deletes the transaction statement data whose confirmation flag is "ON" from the transaction statement file 41 of the IC card 12 ( (Step S19), the storage area of the transaction statement file 41 is arranged (Step S20). At this time, the POS terminal 7 deletes the entire transaction statement data of one credit transaction. However, such erasing of the transaction statement data is performed by deleting many transaction data of one credit transaction. It is also possible to execute only a part.

Therefore, the POS terminal 7, which has deleted and updated the transaction details data of the IC card 12 in step S19, generates updated numerical data for updating the transaction numerical data in accordance with the processing contents (step S21). The updated numerical data is stored in the sales file 3 for each transaction in the RAM 11.
5 is subtracted from the sales numerical data for each transaction code (step S22). In this case, similarly to the conventional cash register minus process, the transaction numerical data is generated again with the transaction statement data, re-input to the transaction-specific sales file 35, and the entirety of the erroneously generated prior transaction numerical data is used as the total for the transaction-specific sales. It is also possible to delete from the file 35.

Further, the POS terminal 7, which has updated the sales numerical data of the transaction-specific sales file 35 in step S22, converts the sales numerical data into predetermined transmission data and transmits it to the file processor 5 (step S2).
3), the file processor 5 receiving the transmission data
Means that the updated numerical data restored from the transmission data is subtracted from the sales numerical data in the product-specific sales file 38 for each product code, and is also subtracted from the sales numerical data in the department-specific sales file 39 for each department code. Again,
As in the conventional cash register minus process, the transaction numerical data is generated again, input again to each of the sales files 38 and 39, and then, the wrong previous transaction numerical data can be deleted.

When the data transmission ends in step S23, the POS terminal 7 completes the registration minus process, and turns "ON" in step S15.
If no confirmation flag is detected, there is no transaction statement data for executing the cash register minus process. Therefore, in these cases, the card reader / writer 13
The card 12 is ejected (step S24), the corrected credit slip is issued by the CAT printer 19, and the card returns to the initial state.

In the POS system 1 described above, the credit transaction cancellation process can be executed as the registration minus process using the registration statement data read from the IC card 12 carried by the customer. Thus, it is not necessary for the clerk executing the cash register minus process to visually recognize the receipt or credit slip and input the product data printed by manual operation of the keyboard 15.
For this reason, in the POS terminal 7, the input operation of the clerk executing the cash register minus process becomes extremely simple, which can contribute to reducing the work load and improving the work efficiency.

The POS system 1 can smoothly execute the cash register minus process, which is the credit transaction cancellation process, as described above. It is possible to prevent disruptions in operations of banks and the like.

Become. Therefore, the P which stores the transaction statement data in the IC card 12
The OS system 1 can accurately and easily execute a credit transaction cancellation process without any problem even when a customer has lost a receipt when performing replacement or return of a defective product.

Further, in the POS system 1, when the credit transaction cancellation processing is executed as described above, the customer may overlap the credit slip before the execution of the cancellation processing and the credit slip thereafter. However, for example, by recording in the IC card 12 that the credit transaction before executing the cancellation processing is invalid, the invalid use of the invalid credit slip can be prevented.

In the POS system 1 which is the merchandise sales registration data processing device of the present embodiment, the use of the IC card 12 as the data storage medium carried by the customer is exemplified, but the present invention is limited to the above embodiment. However, various data storage media that are portable and can freely input and output data, such as a memory card and a magnetic card, can be used as such a data storage medium.

Further, in the POS system 1 which is the merchandise sales registration data processing device of the present embodiment, it has been exemplified that the transaction details data of the IC card 12 which is a data storage medium is updated by deleting it. It is also possible to update the transaction statement data by specifying the execution of the credit transaction cancellation process by setting a flag or the like without executing such data erasure.

Further, in the POS system 1 which is the merchandise sales registration data processing device of the present embodiment, when the credit transaction is canceled, the entire transaction statement data of one credit transaction is canceled. However, the present invention is not limited to the above-described embodiment. For example, it is also possible to partially cancel a large number of product data in the transaction details data of one credit transaction.
