In the commodity order management system having such a configuration, in particular, each of the handy terminals 1
The program is set so that the PU 15 executes each process according to the procedure shown in the flowchart of FIG.

That is, the CP of each handy terminal 1
After turning on the power, U15 first performs initialization processing such as clearing the RAM 17 as ST (step) 1. At this time, a wireless address table T (see FIG. 4) is formed in the RAM 17, and a wireless address a1 assigned to the table T itself, a wireless address a2 virtually given to the order management device 3, A wireless address a3 virtually assigned to the POS terminal 6 is set.

Next, at step ST2, the CPU 15 causes the liquid crystal display 12 to display message data (for example, "Please input the person in charge code") for requesting the person in charge of the customer service to enter the person in charge code. In this state, as ST3, numeric data having the number of digits matching the staff code is entered by the numeric key K2, and when the entry key K3 is subsequently pressed, the numeric data is recognized as the staff code and stored in the RAM 17 in the RAM 17. Remember.

Thereafter, in ST4, message data prompting the liquid crystal display 12 to select an order receiving operation and an accounting operation (for example, "Press the order receiving key to perform the order receiving operation, and press the accounting key to execute the accounting operation.") In this state, if the input of the order key K6 is detected in step ST5, an order receiving business process is executed in step ST6. In other words, by operating the keys on the keyboard 11, the table No. of the table at which the customer who ordered the product arrives and the number of customers, as well as the products of all food and beverage menu products ordered by the customer When the code and the order quantity are entered and the transmission key K10 is finally pressed, the person in charge, the table No., the number of persons, Article code and creates a Denbun the product order data consisting order quantity, antenna 11 the Denbun radio address a2 of the order management apparatus 3 as a destination
This is a process for making a wireless transmission from 0. If the wireless line with the relay device 2 is down, the order management device 3
By inserting the handy terminal 1 into the terminal insertion port, the message of the commodity order data can be directly transmitted to the order management device 3 by optical communication.

On the other hand, when detecting the input of the accounting key 6 in ST7, the CPU 15 executes the accounting business process specifically shown in FIG. 6 in ST8. First, at step ST11, the liquid crystal display 12 displays message data (for example, "Please input the slip number") requesting the input of the slip number of the customer slip which is the customer identification information. In this state, as ST12, numerical data of the number of digits corresponding to the slip number is input by the input key K2, and when the entry key K3 is subsequently pressed (input means), the numerical data is transmitted to the slip.
No. is recognized and stored in the RAM 17.

Next, as ST13, an inquiry message of the settlement information including the above-mentioned slip number is created, and this message is transmitted wirelessly from the antenna 110 to the wireless address a2 of the order management device 3 (file reading means). .

In response to this, when receiving the settlement information message including the order file record of the slip No. transmitted to the own radio address a1 from the order management device 3 via the relay device 2 in ST14, the process proceeds to ST15. The charge amount (total amount of all ordered items + tax amount) is calculated from the information of the received message and stored in the RAM 17 (calculation means).

Next, the charge amount is displayed on the liquid crystal display 12 in step ST16. At this time, message data requesting insertion of the electronic wallet card MC (for example, “Please insert an electronic wallet card”) is also displayed.
In this state, when detecting that the electronic wallet card MC has been inserted from the card slot 14 by the signal of the sensor provided in the IC card reader / writer 113 in step ST17,
As T18, the IC card reader / writer 113 acquires the amount data (remaining amount) from the data (amount, card number, digital signature, etc.) read from the memory of the electronic wallet card MC. Then, in ST19, the balance is compared with the billed amount calculated in ST15 to determine whether or not the balance is equal to or more than the billed amount (determination means).

Here, if the billed amount is equal to or less than the balance, an accounting process using electronic cash is possible. Therefore, in ST20, the billed amount is subtracted from the balance to perform settlement, and the card reader / writer 113 is controlled to control the electronic money. The amount stored in the memory of the wallet card MC is rewritten to the adjusted amount (amount updating means).

Thereafter, in step ST21, the card ejection mechanism of the IC card reader / writer 113 is operated to eject the electronic wallet card MC from the card slot 14. In step ST22, the payment receipt print data by electronic cash transaction is edited based on the content of the payment information message received from the order management device 3. The payment receipt print data is optically transmitted to the corresponding portable printer 8 via the optical communication interface 112 (receipt issuing control means).

Thereafter, as ST23, the electronic cash transaction information including the card number read from the memory of the electronic wallet card MC, the digital signature and the like, the data of the order file record received from the order management device 3, the billed amount, etc. If a message is created and the message is transmitted by radio from the antenna 110 with the wireless address a3 of the POS terminal 6 as a destination, the accounting operation processing is terminated (accounting processing means).

If the response message of the settlement information cannot be obtained from the order management device even after a certain period of time has passed after the settlement information inquiry message is transmitted in ST4, the radio line goes down or the slip number is input. Error due to mistake. ST
If the amount (remaining amount) of the electronic wallet card MC is less than the billed amount at 19, an error occurs because the electronic cash transaction is not established.

The CPU 15 returns to ST2 each time the order processing or the accounting processing is completed, and causes the liquid crystal display 12 to display again the message data requesting the customer service staff to enter the staff code.

In a restaurant where a product order management system using the handy terminal 1 having such a configuration is introduced,
Each customer service representative carries the handy terminal 1 and the portable printer 8 to serve customers. In this case, the service clerk may hold the handy terminal 1 in his hand, and the portable printer 8 may be attached to a clothing belt or the like and carried.

When each customer service representative receives an order for food and drink menu items from a customer who has arrived at the table at the customer seat, he operates the handy terminal 1 as follows. First,
Key in the person in charge code set for yourself. Next, after the order key K6 is pressed to declare the start of the order mode, the table number of the table at which the customer has arrived and the number of customers are input. Thereafter, the customer sequentially inputs the product code and the order quantity of the food and beverage menu product ordered by the customer, and when all the input is completed, presses the transmission key K5. Then, a message of the product order data is created based on the key input data, and the message is wirelessly transmitted.

In this manner, the product order data message transmitted from each handy terminal 11 by radio is received by the antenna 2a of the relay device 2 attached to the ceiling of the customer seat or the like, and transmitted to the order management device 3 via the LAN 7. Can be In the order management device 3, every time the commodity order data message is received, an order file record is created for each customer based on the commodity order data, and the order file record is registered in the order file 32. Further, production instruction data is created based on the commodity order data, and the production instruction data is transmitted to the kitchen apparatus 4 via the LAN 7.
Sent to. Further, customer slip data is created based on the product order data, and the customer slip data is stored in LA.
It is transmitted to the slip issuing machine 5 via N7.

As a result, in the kitchen apparatus 4, product manufacturing instruction information such as the item name of the food and beverage menu items ordered by the customer, the ordered quantity, the table number, and the name of the customer service representative is printed or displayed. The person in charge of cooking manufactures (cooks) the ordered product according to the contents output from the kitchen device 4. The slip issuing machine 5 issues a customer slip printed with a slip No., a table No., the number of customers, and the like, in addition to the item name, quantity, unit price, and the total amount of the food and beverage menu items ordered by the customer. Therefore, the customer service staff distributes the goods to each table according to the customer slip, and when the delivery of all the ordered goods is completed, the customer rep delivers the customer slip to the customer at the table.

When the customer finishes eating and drinking, the customer pays the price, but the method differs between a customer who owns the electronic wallet card MC and a customer who does not own it. That is,
The customer who does not own the electronic wallet card goes to the checkout place with the customer slip as before, submits the customer slip to the accountant, and offers for accounting. Then, the accountant inputs the slip number of the customer slip from the POS terminal 6 by key. Then, the information of the order file record including the input slip No. is transmitted from the order management device 3, and the billing amount is calculated from the information and displayed on the display unit. Will be received from the customer.

On the other hand, when the customer who owns the electronic wallet card MC pays out the price, he or she offers a transaction to a customer service representative while staying at the table. Then, the receptionist operates the handy terminal 1 as follows. First, the operator inputs the code of the person in charge set for himself. Next, after depressing the accounting key K7 to declare the start of the accounting mode, the slip number of the customer slip issued to the customer is input by key. Then, the inquiry message of the settlement information including the input slip No. is wirelessly transmitted from the handy terminal 1 to the order management device 3.

Thus, in the order management device 3,
An order file record including the slip No. in the inquiry message is searched from the order file 32, and settlement information including the order file record is created, and is transmitted to the inquiry handy terminal 1 via the relay device 2 by radio. . On the other hand, in the handy terminal 1 which has received the settlement information, the billing amount is calculated from the information and displayed on the liquid crystal display 12. After confirming the billing amount, the receptionist inserts the electronic wallet card MC owned by the customer through the card slot 14 of the handy terminal 1. Then, the data stored in the memory of the electronic wallet card MC is read by the IC card reader / writer 113, and the amount in the data is compared with the current charge amount. Here, when the amount of the electronic wallet card MC is equal to or more than the billed amount, the amount of the electronic wallet card MC is rewritten by the IC card reader / writer 113 to the amount reduced by the billed amount, and the price accounting processing by the electronic cash transaction is performed. Is completed.

At this time, the payment receipt print data is edited in the handy terminal 1 and optically transmitted via the optical communication interface 112 to the portable printer 8 carried by the customer service representative. As a result, the portable printer 8 prints the item name, unit price, order quantity, and amount of the food and beverage menu items ordered by the customer, as well as the tax amount, total amount, billing amount, and amount of the electronic wallet card MC after settlement. When the payment receipt is issued, the customer service representative passes the payment receipt together with the electronic wallet card MC to the customer. When the customer receives the electronic wallet card MC and the receipt, the customer has finished the accounting and can leave the shop without stopping at the accounting place.

At this time, the handy terminal 1 includes data such as a card number and a digital signature read from the memory of the electronic wallet card MC, data of an order file record received from the order management device 3, a billed amount, and the like. A message of electronic cash transaction information is created and transmitted wirelessly. Thus, the message of the electronic cash transaction information wirelessly transmitted from each handy terminal 11 is received by the antenna 2 a of the relay device 2 and sent to the POS terminal 6 via the LAN 7. In the POS terminal 6, the sales file 61 is updated based on the electronic cash transaction information in the message.

As described above, according to the present embodiment, the customer who owns the electronic wallet card MC can settle the price of the food and drink while sitting at the table, not at the checkout place. As the rate increases, the number of customers who pay at the checkout place can be reduced. As a result, even during a crowded time period, such as during lunch, customers waiting for checkout will not be able to form a line at the checkout place, giving a good impression to the customer.

Further, since the customer can use the electronic wallet card MC to settle the payment while staying at the table, there is no need to go to the checkout place and perform the checkout, and the time until the checkout is completed is shortened. Therefore, serviceability can be improved.

Further, since there is no need to expand the accounting place or increase the number of POS terminals 6, there is no significant increase in equipment costs and personnel costs. Further, when the penetration rate of the electronic wallet card MC is assumed to be 100%, the POS terminal 6 itself can be omitted, and there is no need to provide an accounting place, so that the effect is great.

In the embodiment, a portable printer 8 is prepared corresponding to each handy terminal 1,
The case where the payment print data edited by each handy terminal 1 is transmitted to the corresponding portable printer 8 by optical communication to print and issue a settlement receipt has been shown, but the receipt print data is transmitted as radio waves via the wireless circuit 111. Then, the POS terminal 6 that receives this radio wave (receipt print data) via the relay device 2 may print and issue a settlement receipt. With this configuration, the customer does not have to be at the checkout place for checkout.

Further, in the above-described embodiment, the case where the payment is settled using the electronic wallet card MC in the handy terminal 1 has been described, but the billing amount is sequentially subtracted from the predetermined amount data, and the amount data is changed. The present invention can be similarly applied to the case where the price is settled using a prepaid card which becomes unusable when the value becomes 0.
