The sales promotion information table 71 includes, for example, a down line from the host computer.
Appropriate sales promotion message information is set in advance for each customer group by loading. Here, the sales promotion information table 71 constitutes storage means for setting and storing sales promotion information for the shopper.

When the "register" mode is selected by the mode switch 16, the CPU 41 inputs the PLU code of the product using the preset key 62 or the numeric key 61 and the PLU key 64 of the keyboard 11. Is detected, the program is configured to execute the following product registration work.

That is, first, the registration flag F1 in the flag memory 74 is checked. Here, if the registering flag F1 is reset to "0", it is the first sales registration of the product purchased by one shopper, and thus the registering flag F1 is registered.
1 is set to “1” and the total purchased memory 7
2. Clear the card balance memory 73. If the registering flag F1 is set to “1”, the above processing is not performed because the second and subsequent sales registrations of the product purchased by one shopper are made.

Next, a product file formed in the RAM 43 or the storage device of the host computer is searched to read product data such as a product name and a unit price corresponding to the input PLU code. After calculating the sales price of the registered product by multiplying the unit price by the sales points, the sales data of the sales item and the sales price is registered in a predetermined area of the RAM 43 and classified (PLU code, department code, cashier). Code, time code, etc.). Further, the sales amount is added to the purchase total memory 72.

The number of sales points is set to a multiplier when a multiplier is input by the multiplication key 66 immediately before the input of the PLU code, and to "1" otherwise.

Next, the names and sales prices of the registered products are displayed on the displays 12 and 13. Further, the printer 14 is driven to print the name of the registered product, the sales amount, and the like on the receipt and the journal. Thus, the registration of one product is completed.

When the CPU 41 detects that the balance update key 69 of the keyboard 11 has been operated and input in a state in which the "registration" mode is selected by the mode switch 16, as shown in FIG. The program is configured to check the balance update flag F3 of the above, and to set the flag to "1" if reset.

When the CPU 41 detects that one of the customer layer keys 63 of the keyboard 11 has been operated in the state where the "registration" mode is selected by the mode switch 16, the CPU 41 executes the processing shown in the flowchart of FIG. The program is configured to

That is, it is determined whether or not either the registered flag F1 of the flag memory 74 or the balance update flag F3 of the flag memory 76 is set. If both the registering flag F1 and the balance update flag F3 have been reset to “0”, the customer layer key 63
This process is terminated as a key operation error of.

On the other hand, the balance update flag F3 is set to "1".
When the customer layer code of the customer for whom the balance of the rewrite card 1 is to be updated is input, the customer layer flag of the area 71a corresponding to the customer layer code assigned to the customer layer key 63 input by operation is set. It is set to "1", and the customer layer flag of the area 71a corresponding to another customer layer code is reset to "0". If the customer layer input flag F2 of the flag memory 75 has been set to "1", this processing ends.

When the registering flag F1 is set to "1", since the customer layer code of the shopper who pays for the purchased product using the rewrite card 1 has been inputted, the total purchase memory is stored. The data of 72 is displayed on each display unit 12.13 as the total price of all products purchased by one shopper. Further, the printer 14 is driven to print the total amount on the receipt and the journal. Thereafter, the customer layer flag of the area 71a corresponding to the customer layer code assigned to the customer layer key 63 input and operated in the same manner as described above is set to "1", and the area 7 corresponding to another customer layer code is set.
The customer layer flag of 1a is reset to "0". If the customer layer input flag F2 of the flag memory 75 has been set to "1", this processing ends.

When the CPU 41 detects that the card key 68 of the keyboard 11 has been operated and input in the state where the "registration" mode is selected by the mode switch 16, the CPU 41 executes the processing shown in the flowchart of FIG. The program is configured.

That is, it is checked whether one of the registering flag F1 of the flag memory 74 and the balance update flag F3 of the flag memory 76 is set. If both the registering flag F1 and the balance update flag F3 have been reset to "0", the card key 6
As a key operation error of No. 8, this process ends.

On the other hand, when either the registering flag F1 or the balance update flag F3 is set to "1", the rewritable card reader / writer 80 performs magnetic recording on the magnetic storage unit 3 of the rewritable card 1. It is determined whether or not the read data has been read. If it has not been read, it is determined that a key operation error has occurred on the card key 68, and the process ends.

On the other hand, when the magnetic recording data of the rewritable card 1 is being read, the card data is input via the reader / writer interface 50. And
By analyzing the card data, the card data is checked to determine whether the card is a rewrite card 1 used as a prepaid card, whether the store code 3a is valid, and whether the expiration date 3b has not expired. When it is confirmed that the card is valid as a prepaid card, the balance data 3c in the card data is stored in the card balance memory 73 (card data acquisition means).

The balance data stored in the card balance memory 73 is displayed on each of the displays 12 and 13.

Next, it is checked whether or not the balance update flag F3 is set. If reset, the registering flag F1 is set, and the customer's purchase is paid for with the valid rewrite card 1 as a prepaid card, so that the card payment process specifically shown in FIG. 10 is executed. If so, the process ends.

On the other hand, if the balance update flag F3 is set, the balance data of the rewrite card 1, which is valid as a prepaid card, is updated by an additional amount.
When the card balance update process specifically shown in FIG. 1 has been executed, this process ends.

When it is confirmed that the card is invalid as a prepaid card, a message indicating the invalid card is displayed on the display units 12 and 13, and a card ejection command is sent to the rewrite card reader / writer 20. Is performed, and the process ends.

FIG. 10 is a flowchart showing the card payment process. That is, when this process is started, the CPU
41 first calculates the difference A by subtracting the data in the total purchase memory 72 from the balance data in the card balance memory 73 (data processing means).

Next, as P1, it is determined whether or not the difference A is equal to or more than 0 yen. If the amount is equal to or more than 0 yen, the balance data of the rewrite card 1 is equal to or more than the total amount of the purchased merchandise and the payment can be completed.
A message “Thank you for purchasing” or the like indicating the end of the transaction is displayed in 3.

Further, a command for setting the balance A as a card balance is transmitted to the rewrite card reader / writer 20, and the card balance data 3c in the magnetic storage unit 3 is rewritten to the amount of the balance A, thereby performing a reduction update (data updating means). ).

Next, the customer layer input flag F2 of the flag memory 75 is checked as P3. Here, the customer layer input flag F2
Is set to "1", since the customer layer code has been input by the customer layer key 63, the sales promotion information display processing specifically shown in FIG. 12 is executed (sales promotion information display means).

That is, first, a display erasure command is sent to the rewritable card reader / writer 20 to erase the previous data displayed on the display unit 2 of the rewritable card 1. Next, the sales promotion message information corresponding to the customer layer code in which the customer layer flag is set is read from the sales promotion information table 71. Then, a command for displaying the sales promotion message information is sent to the rewritable card reader / writer 20, and the corresponding sales promotion message information is displayed on the display unit 2 of the rewritable card 1. Thereafter, the customer layer input flag F2 of the flag memory 75 is reset to “0”, and the sales promotion information display processing ends.

When the customer layer input flag F2 has already been reset to "0" at P3, the above-mentioned sales promotion information display processing is not performed.

Thereafter, the CPU 41 sends a command to eject the rewritable card 1 to the rewritable card reader / writer 20, and ejects the rewritable card 1 from the card insertion slot 21. If the printer 14 is driven to print the updated card balance A on the receipt, the flag memory 74
Is reset to "0", and the card payment process is terminated.

On the other hand, if the difference A is negative at P2, the balance data of the rewrite card 1 is insufficient in the total price of the purchased merchandise. Is rewritten and stored, and the difference A is displayed as the shortage −A on each of the indicators 12 and 13.

Also, a command for setting the amount of money “0” to the card balance is sent to the rewritable card reader / writer 20, and the card balance data 3 c in the magnetic storage unit 3 of the rewritable card 1 is transmitted.
Is updated to 0 yen (data updating means).

Next, the customer layer input flag F2 of the flag memory 75 is checked as P5. Here, the customer layer input flag F2
Is set to "1", since the customer layer code has been input using the customer layer key 63, the above-described sales promotion information display processing is executed (sales promotion information display means).

If the customer layer input flag F2 has already been reset to "0" at P5, the sales promotion information display processing is not performed.

Thereafter, the rewrite card reader / writer 20
If a rewrite card 1 ejection command is sent to the rewrite card 1 through the card slot 21,
This card payment processing ends.

FIG. 11 is a flowchart showing the card balance updating process. That is, when this process is started, the CP
U41 waits for the input of the amount data by the key input of the numeral key 61 and the amount key 65 of the keyboard 11 first. Then, when the amount data is input, the input amount is added to the balance data in the card balance memory 73 to calculate the amount B after the increase is updated (data processing means).

Next, a command for setting the amount B as the card balance is sent to the rewrite card reader / writer 20, and the card balance data 3c in the magnetic storage unit 3 of the rewrite card 1 is updated to the amount B (data updating means).

Next, the customer layer input flag F2 of the flag memory 75 is checked as P6. Here, the customer layer input flag F2
Is set to "1", since the customer layer code has been input using the customer layer key 63, the above-described sales promotion information display processing is executed (sales promotion information display means).

If the customer layer input flag F2 has already been reset to "0" at P6, the above-mentioned sales promotion information display processing is not performed.

Thereafter, the rewritable card reader / writer 20
If a rewrite card 1 ejection command is sent to the rewrite card 1 through the card slot 21,
The balance update flag F3 of the flag memory 76 is reset to “0”, and the card balance update process ends.

In this embodiment constructed as described above, the clerk operating the electronic cash register 10, the so-called cashier, registers the merchandise purchased by the shopper with the preset key 62 or the numeric key 61 of the keyboard 11 and the PLU. By operating the key 64 and completing the registration of all the purchased merchandise, the customer layer of the shopper is determined and the corresponding customer layer key 63 is operated.

Here, when there is a request from the shopper to pay for the purchased product by the rewrite card 1 as a prepaid card, the cashier inserts the rewrite card 1 presented by the shopper into the card reader / writer 20. 21 and the card key 68 is operated.

Then, the validity of the rewrite card 1 is determined, and when it is determined that the rewrite card 1 is valid, the balance data of the rewrite card 1 is taken into the card balance memory 73. If the balance data is equal to or larger than the total amount of the purchased merchandise, the balance data of the rewrite card 1 is updated by reducing the total amount, and the payment is completed.

At this time, the promotion message information corresponding to the customer layer code assigned to the key operated customer layer key 63 is read from the promotion information table 71 and displayed on the display unit 2 of the rewrite card 1. Thereafter, the rewrite card 1 is ejected from the card insertion slot 21, and the cashier returns it to the customer together with the receipt.

As described above, the display section 2 of the rewrite card 1 used to pay for the purchased merchandise contains message information that is effective in promoting the sale of the bargain sale date and the recommended merchandise according to the customer class of the shopper. Returned to shopper as displayed. Here, since the rewrite card 1 is used as a prepaid card, the shopper refuses to receive the rewrite card 1 like a receipt or discards the received rewrite card 1 without confirming the contents of the rewrite card 1. There is no such thing as going wrong. Therefore, the possibility that the shopper will confirm the sales promotion message information displayed on the display unit 2 of the rewrite card 1 is extremely high, and an excellent advertising effect can be obtained.

When the customer who owns the rewrite card 1 as the prepaid card offers to increase the balance data of the rewrite card 1,
First, the balance update key 69 is operated. Next, the customer layer of the customer is determined and the corresponding customer layer key 63 is operated. After a while
The cashier inserts the rewrite card 1 presented by the customer into the card slot 21 of the card reader / writer 20, and operates the card key 68.

Then, the validity of the rewrite card 1 is determined, and when it is determined that the rewrite card 1 is valid, the balance data of the rewrite card 1 is stored in the numeric key 61 and the amount key 65.
Is updated by increasing the input amount data to the added amount.

At this time, the promotion message information corresponding to the customer layer code assigned to the key operated customer layer key 63 is read from the promotion information table 71 and displayed on the display unit 2 of the rewrite card 1. Thereafter, the rewrite card 1 is ejected from the card insertion slot 21, so that the cashier returns to the customer.

As described above, even for a customer who has offered to increase the balance data of the rewrite card 1, message information that is effective in promoting sales of a special sale date and recommended products according to the customer's customer class is displayed on the display unit. Since the rewrite card 1 is returned to the customer in the state indicated by 2, the sales promotion message information can be transmitted to this kind of customer with a high probability.

Further, in this embodiment, the rewrite card 1
When the payment of the purchased product is processed with the card balance of, if the card balance is less than the total amount of the purchased product, the card balance of the rewrite card 1 is reduced and updated to 0 yen and discharged. In addition, the display unit 2 of the rewrite card 1 displays sales promotion message information according to the customer class of the shopper.

Here, as described above, the rewrite card 1 can increase and update the balance data at any time within the expiration date, so even if the shopper passes the rewrite card 1 with the balance of 0 yen to the shopper, Reception of the rewrite card 1 is not refused or discarded. Therefore, even in this case, there is a very high possibility that the shopper checks the sales promotion message information displayed on the display unit 2 of the rewrite card 1.

In this embodiment, when the card balance of the rewrite card 1 is smaller than the total amount of the purchased merchandise and the card balance of the rewrite card 1 is reduced to 0 yen and discharged, the shopper rewrites the card. By updating the card balance of the card 1 by increasing, it is possible to pay the shortage with the rewrite card 1.

That is, after the rewrite card with the card balance of 0 yen is ejected, the cashier asks the shopper whether to pay the shortage with cash or with the rewrite card 1.
Then, when there is an offer to pay with the rewrite card 1, predetermined cash is deposited. Then, after operating the balance update key 69, the input of the customer layer is omitted and the card balance becomes zero.
The user inserts the circular rewrite card 1 into the card reader / writer 20 and operates the card key 68.

Then, since the balance update flag F3 is set, a card balance update process is performed. That is, the card balance of the rewrite card 1 is updated by the amount entered by the number key 61 and the amount key 65 and the rewrite card 1 is ejected. At this time, since the customer layer input flag F2 has been reset to “0” by the sales promotion information display processing in the card payment processing immediately before (the processing when the card balance is updated to 0 yen), the sale here is performed. No promotion information display processing is performed.

Thereafter, the cashier inserts the rewrite card 1 into the card reader / writer 20 again and operates the card key 68 again. Then, since the balance update flag F3 has been reset and the registering flag F1 has been set, card payment processing is performed. That is, the card balance of the rewrite card 1 is updated by reducing the shortage of the money, and the rewrite card 1 is discharged. At this time,
Since the customer layer input flag F2 has been reset to "0", the sales promotion information display processing here is not performed.

Therefore, the display unit 2 of the rewritten card 1 discharged after the shortage payment processing is displayed on the display unit 2 when the card balance is updated to 0 yen, according to the customer type of the shopper displayed by the card payment processing. The prompt message information is displayed without being deleted.

As described above, in a continuous transaction for one shopper, the same promotion message information is not repeatedly erased and displayed on the display unit 2 for the rewrite card 1 so that the processing is not repeated. The speed is not reduced, and the overall processing efficiency is not reduced by the display of the sales promotion information.

Further, in this embodiment, since information effective in promoting sales such as a special sale date and a recommended product is displayed on the display unit 2 of the rewrite card 1, there is no need to print it on the receipt. Therefore, the printed contents of the receipt can be simplified, the receipt can be easily viewed, and the receipt paper can be saved.

[0078]

According to the present invention , identification data for automatic message selection such as gender and age are recorded in advance in the magnetic recording section 3 of the card so that the clerk does not need to operate the customer layer key. , The message based on the identification data may be automatically selected and displayed. By doing so, the clerk does not need to judge the customer group, so that the burden can be reduced.

In this embodiment, the case where the rewrite card 1 is used as a prepaid card has been described. For example, when the rewrite card 1 is used as a point card for accumulating service points given for each shopping, it is recorded on the card. It is needless to say that the present invention can be applied to a configuration in which predetermined sales promotion information is displayed on the display unit 2 of the rewrite card 1 every time the cumulative number of service points is updated. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0081]

As described above in detail, according to the present invention, 1
The card-type storage medium that stores the data necessary for processing the data related to the product purchased by the shopper is used to notify the shopper of a message that is effective in promoting sales of the bargain sale date and recommended products. In addition, the present invention can provide an electronic cash register that can transmit sales promotion information in a manner that has a high probability of being confirmed by each shopper and that can achieve excellent advertising effects.
