Abstract

PURPOSE:To perform the cancel processing without requiring any complicated operation nor using the useless communication cost in a short time. CONSTITUTION:It is retrieved whether an internal file of a card processing terminal equipment stores the sales data equivalent to the cancel data or not. If so, only the corresponding data is sent to a host computer and the cancel processing is carried out. Furthermore the sales data equivalent to the cancel data can be erased in the card processing terminal equipment as long as the history of the host computer is not required.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card processing terminal for executing processing of canceling sales data once input.

[0002]

2. Description of the Related Art In a credit card transaction, a store sends sales data to a card company via a card processing terminal for approval, but the sales is less than a predetermined amount (hereinafter, lower limit). No data is sent to the customer, and the sales data is stored in the internal file of the card processing terminal. With such a conventional card processing terminal, when a cancellation process occurs, the data of the voucher you want to cancel is always sent to the host computer, and it can be canceled only when the cancellation data matches the sales data on the host side. However, the sales data stored in the internal file cannot be deleted by the internal processing of the card processing terminal. In addition, because it was not possible to check in advance whether the sales data of the voucher to be canceled is still stored in the internal file or has already been sent to the host computer, the cancellation data is sent to the host side and a cancellation error occurs. Therefore, it was confirmed for the first time that the sales data to be canceled was still stored in the internal file of the card processing terminal. Therefore, if the sales data you want to cancel is not sent to the host side, the operator cancels it, confirms the cancellation error, and then sends the accumulated data in the internal file to the host side all at once and cancels it again. It was

[0003]

As described above, the conventional card processing terminal has a problem that the cancel processing operation is complicated when the sales data to be canceled is not transmitted to the host side. In addition, when collectively transmitting the data stored in the card processing terminal, the host computer to which the data should be transmitted differs depending on the card company, and there are multiple destinations, which causes an increase in communication cost and a long processing time. There was also a problem.

An object of the present invention is to reduce the communication cost by canceling the sales data with a single cancellation process regardless of whether the sales data of the slip to be canceled is on the host side or the card processing terminal side. Another object of the present invention is to provide a card processing terminal capable of reducing the processing time.

[0005]

The present invention is connected to a host computer of a card company through a telephone line, and the sales of less than a predetermined amount of money are input without the approval of the host computer. In a card processing terminal that accumulates sales data in an internal file, a data search unit that searches the internal file for sales data that corresponds to the cancellation data during cancellation processing, and Data erasing means for erasing the sales data in the internal file or transmitting the cancellation data to the host computer depending on the presence or absence of the data are provided.

The data erasing means may include sales data transmitting means for transmitting the corresponding sales data to the host computer.

[0007]

In the cancellation process, when the data of the slip to be canceled is input, the data search means searches the sales file matching the cancellation data in the internal file of the card processing terminal. If the data matching the cancellation data does not exist in the internal file, the sales data matching the cancellation data is canceled in the host computer. On the other hand, if there is sales data that matches the cancellation data in the internal file, and if it is input from the outside that sales and cancellation history is required, the sales data that matches the cancellation data is sent by the sending cancellation means to the host computer. Sent to the host computer for cancellation processing.

Further, when sales data matching the cancellation data exists in the internal file and the history in the host computer is not necessary, the sales data matching the cancellation data is erased in the card processing terminal by the data erasing means. ..

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic view showing a main part of a card processing terminal which is an embodiment of the present invention. The card processing terminal includes a card reader 1, a keyboard 2, a display 3,
And a printer 4, and is connected to a host computer via a telephone line.

On the keyboard 2, numeric keys for inputting numbers such as amounts of money, business keys for selecting processing operations such as sales processing and cancellation processing, a payment classification key for designating a payment method, and an internal file of the card processing terminal. A batch transmission key for collectively transmitting the data stored in the host computer to the host computer is provided. In the transaction, the customer card is passed through the card reader 1 to read the information recorded on the card, and the keyboard 2 is operated to communicate with the host computer to perform the business process selected by the business key. The display 3 displays a response message from the host computer and input data by key operation, and the printer 4 prints the result of communication on a slip.

FIG. 2 is a block diagram showing the configuration of the control unit in the card processing terminal. The CPU 11 having the ROM 12 and the RAM 13 has an interface 1
The card reader 1, the keyboard 2, the display 3, and the printer 4 are connected via 4 to 17, and the interface 21 is connected to the host computer 20 via a telephone line. The CPU 11 centrally controls each input / output device according to a program previously written in the ROM 12, and the data input / output at this time is temporarily stored in a predetermined memory area of the RAM 13. The CPU 11 is the card reader 1
By inputting the keyboard 2 including the sales key 18 and the cancel key 19, the communication with the host computer 20 is performed, and the input data and the communication result are output by the display 3 and the printer 4.

3 and 4 are flow charts showing the processing procedure of the control unit in the sales process and the cancellation process. At the time of card transaction, the CPU 11 waits for the operation of the sales key 18 or the cancel key 19, and when it confirms that the sales key 18 is turned on, waits for the card to be inserted into the card reader 1 and reads the card data ( n1-n3).
Next, sales data such as product category, amount, tax amount, and payment category are input, and when the execution key is turned on, it is determined whether or not the amount M of sales data is equal to or higher than the lower limit (n.
4-n6). The lower limit is predetermined for each store and is stored in a predetermined area of the battery-backed RAM 13. When the amount M is equal to or higher than the lower limit, the sales data is transmitted to the host computer 20, the transmission result is displayed on the display 3, and the printer 4 prints it on the slip (n7, n).
8). On the other hand, if the amount M is less than the lower limit, this sales data is stored in the memory unit of the RAM 13 (tanking) (n9).

When the cancel processing occurs, the CPU 11 confirms that the cancel key 19 is turned on, and then reads the card data inserted in the card reader 1 as in the sales processing (n11 to n1).
3). Next, when the sales data of the voucher to be canceled is entered as cancellation data and the execution key is turned on, the RAM is
It is searched whether or not there is sales data corresponding to the cancellation data in the memory unit 13 (n14 to n16). The processing of n16 corresponds to the data search means of the present invention. In this search, if the corresponding sales data does not exist in the RAM 13, it is determined that the sales data has already been transmitted to the host computer 20, and the cancellation data is transmitted to the host computer 20 to perform the cancellation process, and display and print ( n2
3, n21). If the corresponding sales data exists in the RAM 13, it is determined whether the history in the host computer 20 is necessary (n17), and if the history is not necessary, the corresponding sales data in the RAM 13 is deleted (n22). ). If the history in the host computer 20 is required, the sales data corresponding to the cancellation data in the RAM 13 is transmitted to the host computer 20 (n18),
Thereafter, the cancellation data is also transmitted to perform cancellation processing, display and printing (n19 to n21). N19, n22, n2
3 corresponds to the data erasing means of the present invention, and n18 also corresponds to the sales data transmitting means.

As described above, according to this embodiment, regardless of whether the sales data of the voucher desired to be canceled is on the host side or the card processing terminal side, the sales data can be canceled by a single cancellation process. .. In addition, the cancel processing method can be selected according to whether or not the history is required in the host computer 20, and when the history is not necessary, the sales data is not transmitted to the host computer 20 and the card processing terminal You can also erase with.
