How to manage foreign exchange

The present invention relates to an electronic cash register, and more particularly, to a method of managing a foreign currency divided into dollars, pounds or francs when the transaction is made in a foreign currency through the cash register.

In general, such as in a department store or a convenience store, it is installed in a narrow space in a public place and a place where cash is handled for sales calculation or tax calculation.

Such a cash register is provided with various functions for managing the amount calculation or sale. Learn more about the configuration and operation of such a cash register.

As shown in FIG. 1, the cash register is a display for a user that allows the user to check the details and amount of the buyer's items when the buyer registers the money for the calculation of the purchased item after purchasing the item. 100, a customer-specific display 110 that allows buyers to check the item details, a keyboard 130 for depositing the item details, a printer 120 for printing the item details, Cash box 140 for selling the goods to store the cash deposited from the buyer, and a barcode reader (O, B, R: Optical Barcode Reader (hereinafter referred to as a barcode reader) 150) for recognizing and reading the goods (150) Consists of

The operation of the cash register configured as described above will be described with reference to FIG.

As shown, information such as the microcomputer 140 for controlling the overall operation of the cash register, the ROM 150 for providing various control programs and initial data to the microcomputer 140, and the unit price for each item for sales activities Memory device 160 for storing information such as sales amount generated in sales activity, display units 100 and 110 for displaying various types of information generated from the cash register in the form of characters, and issuing a receipt for the sales history. The printer 120, a timetable for checking the time and the date of sale or clock chip 170 for managing the point of sale, and a keyboard 130 having a plurality of keys for inputting various commands and data. Command or data input by manipulation of a key configured in the keyboard 130 is processed according to a program stored in the ROM 150 under the control of the microcomputer 140. Accordingly, the cash register operates and inputs and outputs data stored in the memory device 160 as necessary. The result processed according to this process is output to the printer 120 or the display unit (100, 110). When a transaction was made in a foreign exchange in a store or a store using a cash register operating in the above-described configuration, the cash register managed the foreign exchange by the exchange rate key on the cash register rather than by type.

For example, suppose that the cash register has an exchange rate key, and the user inputs an exchange rate of 0.00125 for the dollar using the exchange rate key. When a transaction of 10.000 won is made in the real transaction, the customer calculates the dollar. When the user presses the exchange rate key of the cash register, the exchange rate is calculated and the cash register displays 12, which is a dollar amount to be input.

At this time, when the customer pays 20 dollars, the user presses the 20-cash key and closes.

In such a case, the cash register remembers that a foreign currency of 20 is entered for the exchange rate key.

However, if the user wants to use the same exchange rate key used in pounds rather than dollars, then change the exchange rate back to pounds according to the pound and use the exchange rate key again, the cash register uses the same exchange rate key for another foreign exchange. Even though it was not managed separately, it was managed as one information.

Therefore, there is a problem that users of cash registers cannot know what kind of foreign exchange each has entered.

Accordingly, in order to solve the above problems, the present invention comprises a data area for foreign exchange management input into a RAM area as a memory device and a data area for exchange rate keys input into a RAM area. The object of the present invention is to improve the convenience of use and the reliability of the product by allowing the user to manage the foreign exchange more conveniently.

As shown in [Table 1], the types of money and the input amount are arranged for each foreign exchange number. That is, it is a unique number (1-N), and sorts the money type and the input amount by each unique number.

Exchange rate 1 Currency type 1 0 Exchange rate 1 Exchange rate 2 Currency type 2 K Exchange rate 2 2 * K Of Of Of Exchange rate N Currency Type N (N-1) * K Exchange rate N N * K

In addition, Table 2 summarizes the types and rates of currency according to the exchange rates for each unique number.

As described above, the ROM for configuring foreign currency management data and exchange rate keys input to the RAM, which is a memory device, and providing various control programs and initial data necessary for the cash register to operate. There is a feature configured by adding an input program.
