In the PLU file shown in Figure 5, ``Y-Shirt'' and ``Sweater'' are items with no bonus, ``Air Conditioner'' is a 5% discount item, ``Blouse'' is a 10% discount item, and Necktie is a 15% discount item. Next, the operation of this POS system will be explained.

When the host computer 10 starts, the CPU 20
The control program stored in the OM 22 is read and the next operation is performed according to this control program. That is, in this operation, the RAM 24, terminal controller 12, and I/O port 12 are first initialized, and then it is checked whether sales data is being supplied from any of the cash registers 16. When it is detected that sales data has been supplied, a conventional aggregation process is performed based on the sales data. If sales data is not supplied, for example, it detects that each cash register 16 is connected inline, performs a downline loading process to transfer the PLU file from the master file memory to the file memory of the cash register 16, and then sells the data again. It is checked whether data is being supplied from any of the cash registers 16.

On the other hand, when each cash register 16 starts up, the CPU
30 reads out the control program stored in the ROM 32 and performs the operations shown in FIG. 6 in accordance with this control program. When this operation starts, each internal circuit is first initialized in step S1, and then in step S2 it is checked whether the card key has been operated. If the card key is not operated, other processing is performed in step S5, and then step S2 is performed again. Other processing includes processing for receiving a product information record supplied as a PLU file from the host computer 10 and storing it in a magnetic hard disk constituting a file memory. When the card key is operated to designate a transaction using the bonus card, the membership number and payment method are input using the number keys on the keyboard 52 in step S3 and step S4.

After entering the payment method, register the product for sale or step S
It will be held at 6. In this registration process, a PLU code is input from the barcode scanner 58 or the keyboard 52, and a product information record containing a PLU code that matches this PLU code is read from the file memory.

When this registration process is completed, it is checked in step S7 whether a privilege key has been operated. If the privilege key has been operated, magnetically recorded data is read from the card by the magnetic card reader 60 in step S8, and based on this data, it is confirmed that this card is a privilege card.

In step S9, it is checked whether the bonus code of the sold product is "30H". Is it a benefit code for a sale product?”30
If it is detected that the benefit code is not "H", the product information record including this benefit code is stored in the buffer of the RAM 24 in step SIO, and then the sales product registration process is performed again in Stezob S6. 30H'', a message indicating that the product is not a benefit product is displayed on the display in step S11, and in step 510, a product information record including this benefit code is stored in the buffer of the RAM 24, and thereafter, in step S6, the sales product registration process is performed. It will be done again.

If the privilege key has not been operated in step S7, it is checked in step 81B whether the closing key has been operated.

If the close key has not been operated, the sales product registration process is performed again in step S6. In addition, if the close key is operated, a product details displaying the benefit code of each product information record stored in the buffer and the sales amount discounted according to this benefit code is issued in step S14, and the product details are further stored in the buffer. Sales data is created based on all stored product information records. Thereafter, the sales data is supplied to the host computer 10 in step S15, and the buffer in the RAM 34 is cleared in step S16, after which the process returns to step S2. Further, if it is detected in step S8 that the card is not a bonus card, step S1
6 is executed.

In the above-mentioned POS system, a PLU file consisting of a plurality of product information records each including a PLU code, product name data, price data, in-store product code, attribute data, and benefit code of a specific product is stored in the master file memory of the host computer 10. The data is stored in advance, and when each cash register 16 is connected in-line to the host computer 10, it is transferred to this cash register 16 and stored in the file memory of this cash register 16.

When making a transaction using a bonus card at this cash register 16, the product for sale is registered after operating the card key, inputting the membership number, and further inputting the payment method. After registering each product, when you operate the benefit key, it is confirmed that the benefit card is valid, the presence or absence of a benefit is checked from the benefit code included in the product information record of this product, and this product information record is RA ~ 134 buffers. When you operate the closing key in the registration process after registering all sales products for one customer, the benefit code "30H" or "31H" included in the product information record stored in the buffer before operating the closing key is displayed.
32H" and 33H", a product details displaying the discounted sales amount is issued, and furthermore, sales data created based on these product information records is supplied to the host computer 10.

According to this embodiment, each product information record stored in the master file memory includes a benefit code. The product information record is transferred from the master file memory of host computer 10 to the file memory of each cash register 16. The terminal processing unit reads product information records of products corresponding to PLU codes sequentially inputted from the outside from the file memory, and detects benefits of each product from the benefit codes of the read product information records.

In this case, different benefit processing is performed for each product in each cash register 16, and this processing can be reflected in the sales data as, for example, the total sales amount. In addition, the host computer 10 can change the benefit code of the product information record of various products stored as a master verification file in the master file memory, depending on, for example, fluctuations in purchasing prices, which enables more detailed benefit management. . In other words, when the purchasing price of a particular product drops, it is easy to sell this product to loyal customers at an even lower price.

It should be noted that the present invention is not limited to the above-described embodiments, and can be modified in various ways without changing the gist thereof.

In the above-described embodiment, when a product does not have a benefit, this is displayed on the display, but for example, it may be added to display the presence or absence of a premium depending on the benefit coat.

Furthermore, when issuing various benefit cards, benefits such as discount rates may be determined according to the benefit code and the type of benefit card.

[Effects of the Invention] As described above, according to the present invention, it is possible to set different benefits for each product item.
