Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card transaction processing apparatus for selling and registering various products by card, and more particularly to a card transaction for selling a product by giving a subsidy according to the type of card or the type of card holder. It relates to a processing device.

[0002]

2. Description of the Related Art For example, in a company employee cafeteria, it is necessary to sell a large amount of dishes in a short period of time, such as during lunch breaks. It has been put to practical use to read and store the payment together with the read personal ID, and subsequently collectively charge for one month, for example, and collect salary for one month later.

[0003] In some companies, when subsidizing meals for employee welfare, instead of providing cash, a subsidy uniquely set for the dish is provided when the dish is actually purchased. ing. Specifically, when one product (dish) is selected with the menu key, the amount obtained by subtracting the auxiliary amount from the unit price of this product is set as the sales amount, that is, the amount charged to the customer.

[0004] In addition, not only regular employees but also part-time employees, employees of cooperating companies, employees of business partners, and various people use the company cafeteria. Since it is unreasonable to uniformly give the same subsidy to various people belonging to different affiliations, a type (card type) indicating the affiliation of the individual in addition to the personal ID is provided on a card such as an employee ID card. Memorize, and
A plurality of sub-amounts corresponding to the type of each individual are set for each product (dish). Then, at the time of sale of the product, an amount obtained by subtracting an auxiliary amount corresponding to the type read from the card from the unit price of the product is set as the sales amount.

FIG. 11A is a diagram showing an operation unit of a card transaction processing apparatus having the above-mentioned selling function. A menu key 1 on which a plurality of dish names (product names) are written, a numeric keypad 3, and a card reader 3 are provided. FIG. 11B
Is an external view of a card 5 such as an employee ID card, on which a photograph and a name are written and a magnetic stripe 6 is formed. In the magnetic stripe 6, as shown in FIG. 11 (c), a name, an individual ID, an individual type and the like are written. This card 5 has an IC other than the magnetic card described above.
It may be a card.

[0006] In the card transaction processing device, FIG.
The product information table 7 shown in FIG. In the product information table 7, for each product (food) to be sold, a product (food) name, a unit price, an auxiliary amount of type 1, an auxiliary amount of type 2, an auxiliary amount of type 3, and so on are stored. .

In such a card transaction processing device,
The cashier sequentially specifies each product (cook) sold to the customer with the menu key 1, and finally passes the card 5 received from the customer through the card reader 3.
The sub-amount corresponding to the type read by the card reader 3 is subtracted from the unit price of each product specified by the menu key 1 in the above, and the sales amount for each product is obtained. Then, the sales amount of each sold product is added to make the total sales amount.

Further, the sales amount of the product is stored in the product information table 7.
Cashier is the numeric keypad 2 instead of the unit price set in
A card transaction processing device that can be set arbitrarily by using a PC has also been put to practical use. That is, if the menu key 1 is pressed after the sales amount is specified by the ten keys 2, the sales amount of the corresponding product becomes the sales amount specified by the ten keys 2. Then, the sales amount for each product is obtained by subtracting the auxiliary amount corresponding to the type read by the card reader 3 in the product information table 7 from the sales amount specified by the numeric keypad 2.

[0009] In this way, by making it possible to arbitrarily change the sale amount of a product, for example, by executing a discount sale when the best-before period is running short,
The number of unsold products can be reduced. In addition, when the price of the ingredients to be purchased fluctuates greatly depending on the day, the actual sales amount may have to be changed.

[0010]

However, as described above, the card transaction processing apparatus in which the cashier can arbitrarily specify the sales amount has the following problems to be solved.

In other words, when changing the sales amount of each product (dish), the person in charge of the cafeteria determines the optimum sales amount,
Contact each cashier. When each cashier sells the indicated product (dish), it is necessary to specify the changed sales amount with the ten keys 2 before specifying the corresponding product with the menu key 1.

Therefore, the burden on the cashier increases, and the probability of a key entry error in the sales amount increases.
If a key entry error of the sales amount occurs, there is a concern that the following problem may occur.

That is, in consideration of customer complaints, it is rare to set a sales price higher than the unit price, and in most cases, the sales price is set lower than the unit price. However, if you accidentally key in the sales amount to a value less than the replenishment amount,
The value of (sales amount-replenishment amount) becomes (-), and although the merchandise has been sold, the sales amount becomes (-) in a mysterious situation. In this case, the cafeteria pays the amount to the customer. Since such a situation must be avoided,
An error correction operation needs to be performed.

In general, when a key input operation is erroneous, or when the user notices the error immediately before key input, the key input can be easily canceled. But,
In the above-described card transaction processing device, after specifying the sales amount for a plurality of products and specifying the products, when the card 5 is read by the card reader 3, the sales amount for each of the sold products is calculated. I have. Therefore, at this point, it is detected that the sales amount has been erroneously keyed.

However, even if an erroneous operation is detected at this point, the previous key input cannot be canceled. Therefore, a complicated key operation such as a return operation of the same product by inputting the same sales amount again is required. Need to be implemented. Therefore, the burden on the cashier is further increased. further,
Since the cashier rarely remembers the sales amount entered by mistake, the probability that the misoperation can be corrected correctly is reduced.

The present invention has been made in view of such circumstances, and even if the card input operation is the last, if a large amount of erroneous key input is made, the key input is made at the time of key input. An object of the present invention is to provide a card transaction processing device that can output a warning of an input error, reduce the burden on a cashier, and improve the reliability of the entire device.

[0017]

In order to solve the above problems, the present invention provides a card reader for reading card information stored in a card, and a plurality of auxiliary units set for each unit price and card type of each product. A product information table for storing the amount and
When a product is specified by the menu key and then the card information is read by the card reader, the card type is determined based on the card information, and the card type is specified from the unit price of the corresponding product in the product information table. The sales amount of the product is calculated by subtracting the subsidy, and the normal sales means that stores the sales amount together with the card information, and the sales amount is specified by the numeric keypad, the product is specified by the menu key, and then the card is read by the card reader. When information is read and the card type is determined, the amount obtained by subtracting the subsidized amount of the relevant product in the product information table determined from the specified sales amount and specified by the card type is defined as the sales amount of the relevant product, and this sales In a card transaction processing device having an amount-specifying sales means for storing an amount together with card information, a sales amount is specified by a numeric keypad and then a product key is specified by a menu key. At a specified point in time, a comparison unit that compares the specified sales amount with the maximum subsidy amount of the corresponding product in the product information table, and when the sales amount specified by the comparison unit is less than the maximum subsidy amount of the corresponding product. And a warning means for outputting a warning of a wrong designation of the sales amount.

In the card transaction processing apparatus thus configured, at the time when a product is designated by the menu key, the designated sales amount is compared with the maximum subsidy amount, and the sales amount is less than the maximum subsidy amount of the corresponding product. A warning is output when.

More specifically, the subsidy given to the cardholder at the time of selling the product is the type of card determined based on the card information stored in the card, ie, the type of the cardholder who owns the card. Different by type.

However, when the sales amount specified by the cashier using the numeric keypad is less than the maximum subsidy amount for each type of subsidy, the sales amount is always (-) when the sales amount is calculated using a card of the type that specifies the maximum subsidy amount. At this point, it is determined that a key input error has occurred. Therefore, at this point, the cashier can be easily re-entered the sales amount and the merchandise by alerting the cashier of the key input error and canceling the keyed sales amount and the merchandise.

In still another aspect of the present invention, in addition to the card transaction processing device of the above-described invention, an adding means for adding information with assistance to a product to which a subsidy selection application is applied in a product information table. When the sales amount specified by the comparison means is less than the maximum subsidy amount of the corresponding product, and when the relevant product has additional information, the specified sales amount is regarded as the sales amount of the relevant product. A supplementary selling means for storing the sales amount together with the card information is added.

In the card transaction processing apparatus configured as described above, the subsidy is not applied forcibly to all commodities at the time of sale, but is set according to the sales amount designated by the cashier. Is applied or not. If the subsidy is not applied, the specified sales amount will be the sales amount of the corresponding product.

Next, a menu key 1 for specifying a product for sale
If key 3 is operated (S4), and if the sales amount is not stored in number buffer 27 (S5), since the cashier does not specify the sales amount, this product is the corresponding product in product information table 26. The product (dish) name and unit price are read out and displayed on the main display unit 10 (S6). Then, the product code and the product (dish) name of the product are written in an area (line) of the sales buffer 28 in which the sales data is not yet set. Further, the unit price of the corresponding product read from the product information table 26 is written in the sales amount column as the sales amount (S7).
Finally, the calculation end flag is set to "0" (S8).
As described above, the registration processing of the sales data in the sales buffer 28 of one sold product is completed, and the process returns to S1.
The registration operation for the next product is awaited.

In step S5, if the sales amount is stored in the number buffer 27, since this product is a product for which the cashier has specified the sales amount, the auxiliary type of the corresponding product in the product information table 26 is checked. If the assistance type is "no assistance" (S9), the product (dish) name of the corresponding product in the product information table 26 and the sales amount designated by the cashier are displayed on the main display unit 10 (S10). And sales buffer 28
Write the product code and product (dish) name of the product in an area (line) for which no sales data has yet been set. Further, the sales amount designated by the cashier read from the number buffer 27 is written in the sales amount column as the sales amount. Further, the sales amount including tax is calculated with reference to the designated tax category (S1).
1). Finally, the calculation end flag is set to “1” (S
12). Above, sales buffer 2 of one product sold
Since the registration processing of the sales data for No. 8 has been completed, S1
Then, the registration operation for the next product is awaited.

When the auxiliary type is "with auxiliary" in S13 of FIG. 8, the product (dish) name of the corresponding product in the product information table 26 and the sales amount designated by the cashier are displayed on the main display section 10. (S14). And sales buffer 28
Write the product code and product (dish) name of the product in an area (line) for which no sales data has yet been set. Further, the sales amount designated by the cashier read from the number buffer 27 is written in the sales amount column (S15). Finally, the calculation end flag is set to “0” (S16). Above,
Since the registration processing of the sales data of one sold product in the sales buffer 28 has been completed, the process returns to S1 and waits for a registration operation for the next product.

If the auxiliary type is "necessary for auxiliary" in S17 of FIG. 8, the maximum auxiliary amount among the types 1 to 4 of the corresponding product in the product information table 26 is read (S1).
8). Then, the sales amount read from the number buffer 27 and designated by the cashier is compared with the maximum auxiliary amount.
When the sales amount is equal to or larger than the maximum subsidy amount (S19), the main display unit 1 displays the product (dish) name and the sales amount designated by the cashier.
Display at 0. Then, the merchandise code and merchandise (dish) name of the merchandise are written in an area (line) of the sales buffer 28 in which the sales data is not yet set. Further, the sales amount specified by the cashier read from the number buffer 27 is written in the sales amount column (S20). Finally, the calculation end flag is set to "0" (S21). As described above, the registration processing of the sales data of one sold product in the sales buffer 28 is completed, and the process returns to S1 to wait for a registration operation for the next product.

Here, in S19, if the sales amount specified by the cashier is less than the maximum subsidy amount, it is clear that the cashier's sales amount has been incorrectly input. Is performed (S22). And
Without writing anything to the sales buffer 28,
8 is cleared (S23). Then, the process returns to S1, and waits for a correct registration operation for the sale product.

When the card 19 is inserted into the card reader 12 in S24 of FIG. 7, it is confirmed that the sales data of the product is written in the sales buffer 28 (S25).
If the sales data of the product is not stored in the sales buffer 28, an erroneous operation is displayed on the main display unit 10, and the process returns to S1 (S26).

At S25, when it is confirmed that the sales data of the product has been written in the sales buffer 28,
At 27, the card information such as the company code, name, personal ID, and type written on the magnetic stripe 20 of the card 19 by the card reader 12 is read, and a card information buffer 30 is read.
(S30). If the card information cannot be read correctly (S28), a read error is displayed on the main display unit 10, and the process returns to S1 (S29).

Next, one sales data (one line of sales data in FIG. 6) of one or a plurality of sales data written in the sales buffer 28 is read (S3).
1). If the calculation end flag of the read sales data is not set to "1" (S32), it is necessary to calculate the sales amount of the product, and the process proceeds to S33.

In step S33, if the commodity of the read sales data has the auxiliary attribute of “with supplement” set in the commodity information table 26, the supplementary amount corresponding to the type of the commodity stored in the card information buffer 30 Is read (S3
4). If the sales amount of the corresponding sales data is equal to or greater than the read auxiliary amount (S35), the amount obtained by subtracting the auxiliary amount from the sales amount is written in the sales amount column as the sales amount. Sales amount = (sales amount−subsidized amount) Then, the sales amount including tax is calculated with reference to the designated tax category (S36). Finally, the calculation end flag is set to "1" (S38).

If the sales amount of the corresponding sales data is less than the read auxiliary amount (S35), since the auxiliary amount is not applied to the sale of the product, the sales amount is written in the sales amount request as the sales amount. . Sales amount = sales amount Then, the sales amount including tax is calculated with reference to the designated tax category (S37). Finally, the calculation end flag is set to "1" (S38).

As described above, the 1 stored in the sales buffer 28
Since the data processing for the pieces of sales data (for one row) has been completed, if there is any unread sales data in the sales buffer 28 in S43, the process returns to S31 and reads the next sales data.

If the auxiliary attribute of the product of the sales data read out in S33 is not “with auxiliary” but “indispensable in S39”, the auxiliary amount corresponding to the type of the corresponding product stored in the card information buffer 30 is set. Read (S40). Then, the amount obtained by subtracting the subsidy from the sales amount is used as the sales amount.
Write in the sales amount column. Sales amount = (sales amount−subsidized amount) Then, the sales amount including tax is calculated with reference to the designated tax category (S41). Finally, the calculation end flag is set to "1" (S42).

As described above, the 1 stored in the sales buffer 28
Since the data processing for the pieces of sales data (for one row) has been completed, if there is any unread sales data in the sales buffer 28 in S43, the process returns to S31 and reads the next sales data.

If the calculation end flag of the sales data read from the sales buffer 28 is set to "1" in S32, the process proceeds to S43 because it is not necessary to calculate the sales amount of the product. Then, in S43, the sales buffer 2
If there is no unread sales data in 8, the calculation processing of the sales amount including tax of all sales data has been completed, and the sales amount including tax in all sales data in the sales buffer 28 is added to obtain the total amount (invoice amount). ) Is written in the total amount column (S44). The calculated total amount (billed amount) is displayed on the main display unit 10 and the remote display unit 11.

Then, the data of the sales buffer 28 including the total amount (billed amount) is transmitted to the host device 18 with the customer's name and personal ID stored in the card information buffer 30 (S45). Then, the sales data for each product (dish) is totaled in the sales totaling file 29. Finally, the sales buffer 28 and the card information buffer 30 are cleared. This completes the sales registration process for the product (food) sold to one customer.

In the card transaction processing apparatus thus configured, the card 19 of which the type of the individual is type 1 (regular employee)
The display state of the display screen 10a of the main display unit 10 when the customer having the item "Omelette" and "Pilaf" is purchased will be described with reference to FIG. It is assumed that the cashier has been instructed by the cafeteria manager to sell a pilaf with a unit price of 290 yen for a sales price of 200 yen and an omelet with a unit price of 380 yen for a sales price of 400 yen.

The cashier uses the numeric keypad 14 to sell 4
When 00 yen is input by a key and an omelet is designated by the menu key 13, the product name 31b of "Omelet" and the sales amount 31a of "400" are displayed at the top of the display screen 10a.
Next, the cashier accidentally uses the numeric keypad 14 to
If the user enters 0 yen and designates a pilaf with the menu key 13, the sales amount 180 is less than the maximum pilaf subsidy 190 in the product information table 26. An "error" warning and an incorrect 180 sale price 31a are displayed.

Then, when the cashier inputs the correct sales amount of 200 yen using the numeric keypad 14 and designates the pilaf with the menu key 13, the product name 31b of "pilaf" and the correct "200" are displayed on the third line of the display screen 10a. Sales amount 31a
Is displayed.

Next, when the cashier causes the card information of the customer's card 19 to be read by the card reader 12, the total amount including tax (invoiced amount) 211 yen is calculated, and the display screen 10
It is displayed on the fourth line (the last line) of a.

Sales amount of omelet including tax = sales amount-subsidy amount of type 1 = 400-200 = 200 (tax included) Pilaf Sales amount including tax = (200-190) x 1.05
= 11 (excluding tax) Total amount (invoiced amount) = 211 yen In this way, if you incorrectly specify the sales amount of the subsidized product to be less than the maximum subsidy of the applicable product, at this point, the cashier will By alerting and canceling keyed sales and merchandise, the cashier can easily re-enter sales and merchandise. Therefore, the burden on the cashier can be significantly reduced, and the reliability of the entire card transaction processing device can be improved.

Further, as shown in the product information table 26 of FIG. 5, three types of auxiliary attributes of "necessary auxiliary", "with auxiliary", and "no auxiliary" are selectively set for each product. In this way, the subsidy is not forcibly applied to all products at the time of sale, but it is sorted whether the subsidy is applied according to the sales price specified by the cashier .

For example, in a cafeteria, there may be a case where it is desired to set a sales amount lower than the auxiliary amount in order to suppress unsold. In such a case, the application of the subsidy is automatically stopped in order to prevent the sales from becoming (-).
In this case, the designated sales amount is the sales amount of the product. Therefore, it becomes possible to flexibly manage the cafeteria.

The present invention is not limited to the above-described embodiment.

The card 19 used in the embodiment device is
An IC card other than the magnetic card described above may be used.
Further, the card 19 may be a credit card or a prepaid card other than the above-mentioned employee card.

First, the "type" is written in the magnetic stripe 20 of the card 19 in FIG. 3. First, the correspondence table showing the correspondence between the company code and the type shown in FIG. When the card information of the card 19 is read by the card reader 12, the correspondence table is searched by the company code included in the card information,
Type of card holder of this card 19 (type of card)
May be specified.

[0059]

As described above, in the card transaction processing device of the present invention, the sales amount and the maximum subsidy are compared when the sales amount is input in the field operation. Therefore,
Even if the card input operation is the last, if a key value is input by mistake when the sales amount is large, the key input error can be output as a warning at the time of key input, reducing the burden on the cashier and improving the reliability of the entire device. Performance can be improved.
