Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transaction processing device, and particularly to a transaction processing device such as an electronic cash register.

[Prior art] When purchasing a product at a store, there are cases where you have to pay tax along with the price of the product.
Some countries (such as the United States) require tax-free treatment for people receiving public assistance, members of volunteer organizations, etc.

Conventionally, in a transaction processing device such as an electronic cash register, an operator performs tax exemption processing when a person eligible for tax exemption presents his/her certificate.

[Problems to be solved by the invention] However, in conventional transaction processing devices, even if the certificate is stolen or found,
Since it does not have a function to determine this, there has been a problem that the certificate may be misused.

The present invention was made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a transaction processing device that can prevent a certificate for a tax exempt person from being misused.

[Means for resolving the gap] The transaction processing device according to the present invention includes a customer number input means for inputting a customer number, and a check means for checking the customer number input by the customer number input means. , and a control means for permitting tax-exempt transaction processing only when the checking means determines that it is correct.

[Operation] In the present invention, when performing tax exempt transaction processing, the customer's customer number is input and the customer number is checked, thereby preventing misuse of the tax exemption certificate.

[Embodiment] FIG. 2 is a schematic block diagram showing an embodiment of the present invention. In the figure, a CPU 1 has a keyboard 2. Card reader 31 display tube 4. A printer 5 and memory 6 are connected. The keyboard 2 is used to manually input various data to the CPUI. The card reader 3 is for reading a customer's customer number from a magnetic card (or IC card) issued to the customer in advance. The display tube 4 and printer 5 are for displaying and printing output information of the CPUI.

The memory 6 stores information (fourth
This memory is used to store operating programs (see Figure 1) and operating programs (see Figure 1).

FIG. 3 is a diagram showing an example of the key arrangement of the keyboard 2 shown in FIG. 2. In the figure, the keyboard 2 has a number key 21, a customer number key (ACC#) 22, and a tax exemption processing key (XMPT) 2 as keys of interest in this embodiment.
3. The numerical keys 21 are used to input various numerical information, and are used to input the customer number of a tax exempt person when conducting tax exempt transactions. The customer number key 22 is operated to instruct that the numerical information inputted from the numeric key 22 is the customer number of a person eligible for tax exemption. The tax exemption processing key 23 is a key operated to command tax exemption transactions.

FIG. 4 is a schematic diagram showing a part of the storage area of the memory 6 shown in FIG. 2. In the figure, numerical data storage area A stores numerical data input from the numerical keys 21 of the keyboard 2. The transaction caution customer code file NCF stores the defective customer number in area a and stores the defective customer number in area b.
remembers negative information. Here, the defective customer number is a customer number of a person eligible for tax exemption whose tax exemption certificate has been lost or stolen, and which has been reported to the store opening in advance. The negative information stores information such as the reason why the corresponding customer number is considered defective.

FIG. 5 is a diagram showing an example of key operations during tax-free transactions, which is of interest to this embodiment. FIG. 1 is a flow chart for explaining the operation of the above embodiment. below,
The operation of the above embodiment will be explained with reference to FIGS. 1 and 5.

When processing a tax-free transaction, the operator first presses the tax-free processing key 23, as shown in FIG. Correspondingly, the CPU imports the key (step S1) and determines whether the tax exemption processing key 23 has been pressed (steps S2 and S3).

Next, an input check (checking whether transaction information has already been entered, etc.) is performed (step S4), and OK is entered.
If not, error processing is performed (step S5), and O
In the case of K, it is determined whether checking the customer number of the person eligible for tax exemption is a mandatory condition (step S6). In addition,
Information on this forced condition is stored in an area (not shown) of the memory 6. If checking the customer number is not a compulsory condition, the process proceeds to other processes, but if it is a compulsory condition, a display requesting input of the customer number is displayed on the display tube 4 (step S7).

Next, the operator inputs the customer number of the person eligible for tax exemption using the numerical keys 21, as shown in FIG. The customer number entered by this numeric key 21 is taken into the CPU 1 and stored in the numeric data storage area A (steps Sl, S2
and S8). Next, the customer number stored in the numerical data storage area A is displayed on the display tube 4 (step S9).
.

Next, as shown in FIG. 5, the operator presses the customer number key 22. In response, the CPU 1 captures the key (step S1) and determines that the pressed key is the customer number key (steps S2, S3 and 510). Next, the process proceeds to step Sll, and the numerical data storage area A is checked (step Sll).
. That is, it is checked whether a customer number of a predetermined number of digits is already stored in the numerical data storage area A, and if it is not 0, an error process is performed (step 512). On the other hand, if the check result is OK, a search is made to see if there is a number that matches the currently input customer number (stored in numeric data storage area A) in the transaction caution customer code file NCF. (Step 513). If the customer number in question is not registered in the transaction caution customer code file NCF, the input customer number is not a defective number, so normal tax-free transaction processing is performed (steps 514 and 515). On the other hand, if the corresponding customer number is registered in the transaction caution customer code file NCF, tax-free transactions are prohibited and the negative information stored in the corresponding area b in the transaction caution customer code file NCF is displayed on the display tube 4. Display (step 516). This allows the operator to know that the input customer number is a defective customer number. Subsequently, error cancellation processing is performed (step S17), and the process returns to step S1.

In the above operation explanation, the case where the customer number is input from the numeric keys 21 has been explained, but when the customer number is input from the card reader 3, as shown in FIG. Card information (customer number) is read.

In this case, suppression of the customer number key 22 is not necessary and the first
The operation in step S10 in the flowchart shown in the figure is a card information reading operation.

Further, as the customer number, in addition to the number assigned in advance to the customer when the store is opened, the issue number of the tax exemption certificate may be used.

[Effect of the invention] As described above, according to this invention, when conducting tax-free transactions,
By checking the entered customer number, the following effects can be obtained.

(1) If a person who has had their tax exemption certificate stolen or dropped reports it to the store, the number will be registered as an unusable number, thereby preventing fraud.

(2) Customer - Purchases of 22 units per month per person.

You can manage the number of types, etc.

(3) By assigning meaning to the customer number, it is possible to grasp the customer base.

(4) Since the certificate holder can be identified by the customer number,
If you lose your certificate, you can keep it at the store.
