Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention provides one or more POS (Point Of Sales=
Point of sale, hereinafter simply referred to as "POS". ) A method of processing transaction data in a system comprising a terminal device and a central host machine.

(2) Background of the technology Normally, a POS terminal device adds and records its own transaction data in its memory, and prints out the total sales from the opening of the office to the closing of the office and sends it to the center when the office is closed. Output to the host machine and clear the memory contents. Normally, payment is made after the sales floor is closed, that is, after the closing point, but 1 to 2 hours before closing.
In sales areas where the number of customers decreases, payment should be made early before closing to reduce congestion during post-closing payment operations (checking total sales and cash balance, reporting to accounting, cash delivery, etc.) I often get things done.

(3) Prior Art and Problems Figure 4 is a time chart showing a conventional transaction data processing method.

However, conventionally, when a settlement signal is input from a POS terminal device, the center host machine closes the file related to the terminal device, and even if transaction data is subsequently input from the terminal device, the data is rejected as an error. With this, it is not possible to deal with transactions that occur after settlement, so as shown in Figure 4, two files, 4A and 4B, are prepared on the center host machine, and the transaction data DATA before settlement is stored in file 4A. A method was also used in which the data from the terminal device that was opened again after the station was closed for settlement was stored in the file 4B. It was necessary to calculate the total sales for one day by adding up the transaction data, which had the disadvantage of complicating the process.

(4) Purpose of the Invention In order to eliminate the above-mentioned drawbacks, the present invention combines transaction data stored in separate files before and after payment without discarding transaction data from a POS terminal after payment. The purpose is to provide a method for processing unnecessary transaction data.

(5) Structure of the Invention In other words, the present invention provides a POS terminal device with a means for specifying interim payment and a means for instructing a sales total request, and also provides a current day file and a next day file on the central host machine, and sends out files from the terminal device before the interim settlement. The transaction data to be processed is stored in the file for the current day, and after the interim settlement is performed by the interim settlement specification means, the transaction data from the terminal device where the interim settlement was performed is stored in the file for the next day, and the transaction data is stored in the file for the next day. , the next day's file is set as the current day's file, and the sales total request instruction means stores the total sales from the current day's file from the previous day's partial settlement to the closing of the station in the terminal device, and the transaction data after the partial settlement is stored on the next day for the next day. It is configured to be processed together with transaction data.

(6) Embodiments of the Invention The present invention will be specifically described below based on embodiments shown in the drawings.

Fig. 1 is a block diagram showing an example of a transaction recording system to which the present invention is applied, Fig. 2 is a block diagram showing details of a POS terminal device and a central host machine in the system of Fig. 1, and Fig. 3 is a block diagram showing the details of a POS terminal device and a central host machine in the system of Fig. 1. 1 is a time chart showing an example of a transaction data processing method according to the present invention.

The transaction recording system 1, as shown in FIG.
It has a center host machine 2, and a plurality of POS terminal devices 5A, 5B, 5D are connected to the host machine 2 via a line 3.
...is connected. Each terminal device 5A, 5B, 5
As shown in FIG. 2, D... has a control section 6, and the control section 6 includes a sales total request instruction means 9 provided as a key switch on a keyboard 7, an intermediate settlement specification means 8, A receiving means 11, a transmitting means 12, and a message creation and decoding means 13 are connected, and a memory 16 connected to a keyboard 7 provided with a setting means 8 and the like is further connected to the creation and decoding means 13 via a buffer memory 15. There is. On the other hand, the center host machine 2 has a transmitting means 17 connected to the receiving means 11 via the line 3, and a receiving means 19 connected to the transmitting means 12.
9 is connected to the current day's file 22 and the next day's file 23 via a file switching means 21.

Since the present invention has the above configuration, each
POS terminal devices 5A, 5B, 5D, . . . are arranged in each sales floor, and a POS number PNO starting from “1” is stored in the memory 16 and attached to each device. For transactions occurring in the sales floor, data such as product name and sales amount are entered as transaction data DATA via keys provided on the keyboard 7 of each terminal device 5A, 5B, 5D, etc., and stored in the memory 16.
is stored in On the other hand, the control unit 6 sets the transaction serial number in the memory 16 to an initial value of "0" at the time when the operator opens the terminal device due to opening of a store, etc., and thereafter sets the serial number to the initial value "0" every time a transaction is recorded. The value is added up one by one one by one and added to the transaction data DATA input from the keyboard 7 to the memory 16. Transaction data stored in memory 16
DATA is read out to the message creation/decoding means 13 via the buffer memory 15 for each transaction serial number, transmitted by the transmitting means 12 to the receiving means 19 of the center host machine 2 via the line 3, and then transferred to the file switching means 21 of the host machine 2. The data is stored in the file 22 for the current day. The switching means 21 is normally switched to the current day's file 22, and all transaction data DATA from each terminal device is transferred to the current day's file 22.
is stored in.

Next, when the closing time approaches and the operator wishes to make a payment for a specific terminal device, for example 5A, before closing, the operator operates the partial payment designation means 8 provided on the keyboard 7 of the device 5A to It outputs the settlement signal TSS to the host machine 2, calculates the total sales, etc., and performs settlement operations up to that point.
In addition, the file switching means 21 of the host device 2 is driven by the signal TSS, the current day file 22 of the terminal device 5A is closed, and the next day file 23 is opened, and from now on, that is, after intermediate payment, the file switching means 21 of the host device 2 is driven. All transaction data DATA is stored in the file 23 the next day. As shown in FIG. 3, the device 5A is closed when the station is closed, but the host machine 2 confirms that all the devices 5A, 5B, etc. are closed and stores the transactions stored in the file 22 on that day. We perform aggregation work only on data and calculate total sales, etc. At this time, the transaction data DATA stored in the next day file 23 of the device 5A
However, since there are usually fewer customers near closing time and therefore fewer transactions at sales floors where payment is made mid-way, transaction data in the next day's file 23 is not included.
Even if DATA is excluded from the current day, there will be no significant errors in aggregation.

Next, the next day, when the station opens, the operator operates the sales total request instruction means 9 of the terminal device 5A to send the sales total request signal TWC to the host device 2 via the message creation and decoding means 13 and the transmission means 12. . On the other hand, in the host machine 2, as the system 1 starts operating, the file switching means 21 is switched and the next day's file 23 of the previous day is updated to the current day's file 22. The total sales TOTAL regarding the terminal device 5A is read out and sent to the receiving means 11 of the device 5A via the transmitting means 17, and further stored in the memory 16 via the message creation/decoding means 13 and the buffer memory 15. In this state, when the operator inputs transaction data DATA that occurred after the opening of the station, those data DATA will be stored in the memory 16 and the updated current day file 22 of the host machine 2, and will be stored in the data DATA input after the previous day's interim settlement. Transaction serial numbers are stored sequentially. That is, the transaction serial number in the POS terminal device 5A (one serial number assigned to each transaction)
is not cleared even when the store closes and is retained in non-volatile memory, and the next day the transaction starts from the previous day's transaction serial number + 1 (the transaction serial number is set to the initial value of "0" due to the previous day's interim settlement. It will be reset, and from then on, a series of serial numbers will be assigned until the next day's partial payment.) Therefore, the transaction data DATA after the previous day's partial settlement is all processed together with the data DATA up to the next day's settlement, but as already mentioned, the transaction data DATA after the previous day's partial settlement is usually small. Therefore, there will be no large error in the total sales for the next day.

(7) Effect of the invention According to the present invention, the POS terminal devices 5A, 5B, 5
A mid-term payment designation means 8 and a sales total request designation means 9 are provided on the D... side, and a same-day file 22 and a next-day file 23 are provided in the center host machine 2. , the subsequent transaction data DATA from the terminal device 5A is the previous day's file 22.
The next day, the next day's file 23 is set as the current day's file 22, and the sales total request instruction means 9 records the total sales from the previous day's interim settlement until the office closes from the file.
TOTAL is stored in the terminal device 5A, and the transaction data DATA after mid-payment is processed together with the next day's transaction data DATA on the next day, allowing early payment processing at sales floors where the number of customers is decreasing before closing. Even if a transaction occurs between then and the store closes, all such transaction data DATA will be processed as the next day's data.
is not rejected as an error, and there is no need to add up the transaction data DATA before and after settlement, and the processing associated with settlement on the center host machine 2 side can be performed quickly.
