Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a household management system and method, and more particularly, to a dedicated device (hereinafter referred to as a "dedicated device") in which a customer connects an IC card reader by recording customer purchase data on the IC card in a POS using the IC card. Or a personal computer (PC) to read and input the household management data automatically and to process automatically.

[0002]

2. Description of the Related Art As a conventional household management system, there is a POS terminal with a household account book function and a store management apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 8-279079.

FIG. 4 is a diagram showing the configuration. In FIG.
10 is a store side management device, 11 is a first storage device, 12 is a second storage device, 13 is a processing mechanism unit, 20 is a POS terminal, 21 is a printing device, 22 is a processing mechanism unit, 30 is a communication mechanism, B is a household account book output, and R is a receipt output.

[0004] As shown in FIG. 4, the store-side management device 10 includes a processing mechanism unit 13, and the POS terminal 20 includes a processing mechanism unit 2.
2 is provided.

[0005] The processing mechanism section 13 performs control of its own device and the connected POS terminal 20 and various arithmetic processing by external instructions or automatically. Also,
It also has a communication control function.

[0006] The POS terminal 20 includes a processing mechanism section 22. The processing mechanism unit 22 includes a bar code reading device, a display,
It has a keyboard, communication means, etc., and responds to customer transactions.

The POS terminal 20 records transaction data for each customer code or ID code and transmits the transaction data to the store management device 10. The store management device 10 aggregates data for each customer and provides a request. You will need to return this accordingly. Therefore, the POS terminal 20 needs to have a means for inputting information about the customer.

[0008] Such an input means can be a normal keyboard, but in order to prevent complication of input and occurrence of erroneous input, it is preferable to use an ID card reader or a credit card reader. it can.

[0009] Such an input means may be any means as long as the personal information can be surely confirmed, and may be, for example, a means for optically reading a driver's license, a passport or the like.

It is desirable that the output by the printing device 21 be capable of performing both the print output of the receipt output R and the print output of the household account book B during a normal transaction.

However, since the contents included in the receipt and the household account book are different from each other, and therefore the printed contents are also significantly different, the printing device for the receipt is built in the device as before and the printing device for the household account is separately provided. Or it can be configured to be connected as an external printer.

When the customer has completely entered all the information on the product to be purchased, the transaction mechanism 22 transmits the transaction information from the POS terminal 20 to the store management apparatus 10 via the communication mechanism 30. You.

The transaction information for each customer is controlled by the processing mechanism unit 13 in the store management apparatus 10, and includes, for example, a customer code, a product code, a unit price, a quantity, a total, a terminal device number, a product handling department, a date and time, and a handling. All of the user names and the like are stored in the storage device 11.

Among these transaction information, information necessary for creating a customer's household account book, for example, a customer code, a code of a transaction product, a price, a quantity, a total, and the like are transferred to the second storage device 12 at an appropriate time. Is stored.

Therefore, the second storage device 12
It is desirable to have a capacity capable of storing information for an appropriate period, for example, a predetermined period such as three months, six months, or one year.

The store management device 10 converts the information belonging to the customer code from the contents for creating the household account book stored in the second storage device 12 in response to the household account book output request from the customer.
It can be arranged for each desired period, transmitted to the POS terminal 20, and printed out.

At the end of the month, for example, at the end of the month, the printing output of the household account data is collectively printed by a printing device attached to the store management device 10 and, at the end of the month, is printed at the customer's request or determined by the store. Can send.

Also, an online access function is provided to the store management apparatus 10 so that the customer can
, And output the data directly to the customer terminal. The first problem is that it is necessary to manually input purchase information into household account book software, and the input of purchase information cannot be automated.

The second problem is that when providing the customer with the customer's purchase information stored in the POS terminal and the data center at the store side, complicated procedures or authentication means are required. is there.

[0020]

The first problem with the above-mentioned conventional household management system and method is that protection of leakage of customer's household information from the outside is insufficient.

The reason is that since the transaction data is recorded for each customer code or ID code, the transaction data can be easily obtained only by the customer code or ID code.

It is an object of the present invention to record customer authentication information (consisting of an ID and a password) and purchase information such as a store name, date and time of use, purchase items, prices, and quantities on an IC card, and read the purchase information. Accordingly, it is an object of the present invention to provide a household management system and a method for automatically inputting and processing household management data and preventing external leakage of customer household information.

[0023]
