DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a commodity sales data processing apparatus capable of processing payment by credit.

[0002]

2. Description of the Related Art FIG. 5 shows the configuration of a general POS (point of sale information management) system used in department stores and the like. The store processor (SP) 1 manages the entire system, and a plurality of POS terminals (TM) 3 are connected to the store processor 1 via a file processor (FP) 2. The file processor 2 and each POS terminal 3 are connected inline by a communication line 4 to form a closed loop.

Each POS terminal 3 has a function of registering product sales data, and is distributed and installed in each sales floor. The file processor 2 is each POS terminal 3
The merchandise sales data registered in (1) is collected through the communication line 4, and is classified and classified by, for example, merchandise or sales floor.

The store processor 1 has a function of setting necessary data in the storage unit of the file processor 2 and each POS terminal 3, and collects and processes the data aggregated by the file processor 2 to analyze the sales of the entire store. It is equipped with a function to perform.

Each POS terminal 3 has a card reader for reading the card information of a credit card and a slip printer for printing a credit sales voucher, and can process payments by credit. The file processor 1 is online connected to a host computer 5 of each credit card issuing company via a public line or a dedicated line 6.

[0006] When a customer offers to pay by credit at a certain sales floor, the clerk first registers the sales data of the product purchased by the customer in the POS terminal 3. Next, the clerk inputs a credit sales key provided in the POS terminal 3 to instruct payment of credits, and reads card information of a credit card possessed by the customer with the card reader.

Then, at the POS terminal 3, a message inquiring about the establishment of credit is created and transmitted based on the registered product sales data, card information and the like. This inquiry message is transmitted to the store processor 1 through the file processor 2 and further to the host computer 5 of the corresponding credit card issuing company through the public line or the dedicated line 6.

[0008] The host computer 5 determines the credit establishment from the inquired credit information, and returns a response message indicating the determination result to the corresponding POS terminal 3.

At the POS terminal 3 which receives this response message, the establishment of credit is checked from the message,
If the establishment of credit is approved, the slip printer is operated to print and issue a credit card sales voucher.
Also, transaction data indicating the content of credit is created. This transaction data is collected and managed by the store processor 1 via the file processor 2 at appropriate times.

FIG. 7 shows an example of the credit card sales slip 7. This credit card sales slip 7 is generally
In addition to the customer signature field 71, a card issuer print field 72, a customer membership number print field 73, a credit handling date print field 74, a credit card expiration date print field 75, and a slip number print field 76, A print column 77 for the product classification code, a print column 78 for the total amount paid by credit, and the like are printed in advance. Then, the slip printer is programmed to print the corresponding data in each print field other than the signature field 71.

Here, the product classification code printed in the print field 77 is a classification code of a product whose price is paid by credit, and is a code required by the CAT (Credit Authorization Terminal) specification. . For example, the product category code for general use is "00
0 ”, the food product classification code is“ 890 ”, the electric product classification code is“ 650 ”, and the television product classification code is“ 654 ”.

This product classification code must be keyed in each POS terminal every time a payment service by credit occurs. However, since the product classification codes used in most of the sales floors are common, conventionally, the store processor 1 is provided with a code table 8 for setting and storing the product classification code for each terminal number of each POS terminal as shown in FIG. When the input of the product classification code is omitted at the POS terminal, the slip printing or the like is processed by the product classification code corresponding to the corresponding terminal number preset in the code table 8.

For example, in the case of the code table 8 shown in FIG. 6, the POS terminal 3 with the terminal number "0001" and the POS terminal 3 with the terminal number "0002".
Are installed in the grocery section, and "890" is preset as the product classification code. Also,
The POS terminal 3 with the terminal number "0003" is installed in the home appliance section, and has a product classification code of "65".
0 ”is preset. Further, the POS terminal 3 with the terminal number "000n" is installed in the special television corner of the home electric appliance section, and "654" is preset as the product classification code.

Then, for example, when an electric product other than a television is purchased by credit at the home appliance section and the registration of the product is processed at the POS terminal 3 with the terminal number "0003", the product classification code "650".
Even if the input of is omitted, the response message for approving the credit from the store processor 1 includes the product classification code “650” read from the code table 8, so that the print column 77 of the credit sales slip 7 shows the product classification code “650”. The product classification code “650” is printed.

[0015] Similarly, a television is purchased by credit at the home appliance section, and the terminal number "000"
When the registration of the product is processed at the POS terminal 3 of "n", even if the input of the product classification code "654" is omitted, the code table 8 is included in the response message for approving the credit from the store processor 1. Since the read product category code “654” is included, the credit sales slip 7
The product classification code “654” is printed in the print field 77 of.

However, each POS terminal 3 is usually
Even if the communication line up to the store processor 1 is disconnected and it is not possible to inquire of the higher-end model about the feasibility of credits, if the amount paid by credits is less than or equal to the preset upper limit, credit approval function, so-called credit It has a local processing function.

In this credit local processing, since the product classification code cannot be received from the store processor 1, when the input of the product classification code is omitted, the credit sales slip 7 in which the printing column 77 is blank is issued. .

[0018]

As described above, in the conventional POS system of this type, each POS terminal 3
If the communication line is not connected and the credit local processing is performed at each POS terminal 3, enter the product classification code that could be omitted if the communication line between the store processor 1 and the store processor 1 is connected. Must be
There was an undeniable decline in work efficiency.

Therefore, according to the present invention, even when the communication line with the host is not connected and the credit payment is processed by the credit local process, the product classification code is the same as when the communication line with the host is connected. It is intended to provide a product sales data processing device that can omit the input of.

[0020]

According to the present invention, there is provided a product classification table for setting and storing a default value of a product classification code for classifying products whose price is paid by credit. Then, the line connection state with the host computer is checked every time the payment of credit for the product registered for sale occurs. As a result, if it is confirmed that the line with the higher-level computer is connected, the higher-level computer is inquired about the credit establishment, and when the response message approving the credit is received from the higher-level computer, the product included in the response message is received. The slip is printed with the credit detail information including the classification code. On the other hand, if it is confirmed that the line with the host computer is not connected, the success of the credit is judged without inquiring to this host computer, and if the credit is approved, the credit including the product classification code stored in the product classification table The detailed information is printed on the slip.

[0021]

According to the present invention having such a configuration, the commodity classification table which is frequently used in the sales floor where the apparatus of the present invention is installed is preset in the commodity classification table as a default value.

In this state, when payment for the registered product by credit occurs, the line connection state with the host computer is checked. When the line with the host computer is connected, an inquiry is made to this host computer, and when a response message approving the credit is received, the credit statement information including the product classification code included in the response message is displayed. The slip is printed. On the other hand, when the line with the host computer is not connected, the credit validity is determined without inquiring the host computer, and when the credit is approved, the credit statement information including the product category code stored in the product category table is displayed. The slip is printed.

Therefore, even when the device of the present invention is not connected to the communication line with the host and the payment of credit is processed by the credit local process, the input of the product classification code can be omitted.

Next, the store clerk inputs a credit sales key 37 provided in the POS terminal 3 to instruct payment of credit, and reads card information of a credit card possessed by the customer with the card reader 27.

If the product purchased by the customer is an electric product, only the classification key 40 is keyed in, and the number input of the product classification code is omitted. Then, the work area 54
Is set to the default value "650" of the product classification code preset in the product classification table 53.

When the communication line up to the store processor 1 is disconnected and it is not possible to inquire of the higher-ranking model about the feasibility of credit, it is checked whether or not the amount of payment by credit is less than or equal to a preset upper limit amount. To be done. When the amount is less than or equal to the upper limit, the credit is approved, the credit card sales slip 7 is printed by the slip printer 28, and transaction data of credit sales is created and stored in the transaction file 57.

Here, the data set in the work area 54 is printed in the product classification code printing field 77 of the credit card sales slip 7. That is, the default value “650” of the product classification code preset in the product classification table 53 is printed. Further, the default value “650” of the product classification code is also incorporated in the transaction data of credit sales and stored in the transaction file 57.

In addition, when a commodity other than an electric appliance is traded by credit in the home electric appliance section, the cashier counts the classification code of the corresponding commodity with the numeral key 31 and then
Enter the classification key 40. Then, the product category code keyed in is set in the work area 54.

Also in this case, the credit card sales slip 7

Therefore, even when the communication line up to the store processor 1 is disconnected and it is not possible to inquire of the higher-level model regarding the credit establishment, the corresponding product classification code is the product classification code stored in the product classification table 53. When it matches the default value, the key input of the product classification code can be omitted.

That is, according to the present embodiment, the key input of the product classification code can be omitted in the same manner as when the communication line with the host is connected, so that the work efficiency can be improved when the payment by credit occurs. It can be planned.

Further, when the communication line up to the store processor 1 is connected and it is possible to inquire of the higher-ranking model about the credit establishment, the POS terminal 3 is based on the registered merchandise sales data and card information. A message for inquiring about the establishment of credit is created. By incorporating the product classification code set in the work area 54 into this inquiry message, it is possible to add the product classification code from the upper layer to the response message. Easy to implement. By doing so, the conventional store processor 1
Since it is possible to eliminate the commodity classification table 8 that was necessary in step 1, the processing time required for inquiries can be shortened.

The present invention is not limited to the above-mentioned embodiments, and it goes without saying that various modifications can be made without departing from the gist of the present invention.
