DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for deducting a sales amount from the amount information as a balance written on a prepaid card.
The present invention relates to a card terminal device provided with a split billing processing function of performing a so-called split billing method (that is, a method of sharing a common sales amount with a plurality of related parties (accordingly, a card owned by the related parties) and paying).

[0002]

2. Description of the Related Art In a conventional card terminal device, for example, a unit price of a product for sale is set, and when paying with a prepaid card, the unit of the product is deducted at once for a card having a balance over the unit price of the product. I was

[0003]

As described above, in the conventional card balance processing method, since the sales amount is deducted in one processing, there is a demand to pay two or more (two or more) cards equally. I couldn't handle it. Therefore, even when two or more users want to pay for a taxi or the like used jointly, one person wants to make a payment or two or more joint buyers want to pay for the total amount of the joint purchase. Even in that case, one person had to make a change. Therefore, an object of the present invention is to provide a card terminal device with a split billing function that can solve this problem.

[0004]

In order to solve the above-mentioned problems, a card terminal device according to claim 1 reads at least a balance in a prepaid card (1 or the like) inserted, and reads a corresponding sale from the balance. In a card terminal device for updating a previous balance with a new balance that has been deducted, a split-budget processing designating means (split-budget mode start switch, keyboard 5, etc.) for designating and inputting a predetermined split-budget processing, and sales to be split-budget Based on the means (such as the keyboard 5) for inputting the amount (such as the commodity price B) and the input of the split billing process and the input of the split billable sales amount, the number of the split billable sales amount is increased for each insertion of the prepaid card. Divide the sales amount by 1
A means for deducting by the division (such as the operation control unit 6), and an unbalanced fraction of the sales amount subject to the billing incentive which is caused by a minute discount from the prepaid card based on the designation of the billing processing designation means (the last unpaid amount) C, fraction correction subtraction amount A1, etc.)
(A control operation unit 6 or the like) for performing the withdrawal at the last time of insertion of the prepaid card.

According to a second aspect of the present invention, in the card terminal device according to the first aspect, the split-budget processing designating means includes a common amount (a unit deduction amount) to be deducted at least every time a prepaid card is inserted. A, etc.).

According to a third aspect of the present invention, in the card terminal device according to the first aspect, the split-budget processing designating means is configured to determine at least an amount to be deducted for each insertion of a prepaid card. The number of divisions (such as the number of split bills G) of the sales amount to be split is designated and input.

[0007]

The card terminal device is provided with a switch or the like for activating the split billing function, and a common payment is divided and a balance processing for debiting from a plurality of cards is performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a block diagram showing a main part configuration of a card terminal device as an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a prepaid card in which amount data is stored magnetically, and 2 denotes a card reader / reader for reading and writing the data.
Writer (abbreviated as card R / W), 3 is a monitor display for displaying money information, etc., 4 is a memory, 5 is a keyboard for inputting setting data, etc., 6 is arithmetic control for controlling these means 2-5. Department. In the present invention, a switch 7 for activating the split billing mode is added to the above configuration.

FIGS. 2 to 4 are flow charts showing an embodiment of different splitting processing of the arithmetic and control unit 6 of FIG. Next, FIGS. 2 to 4 will be described with reference to FIG. In the following, reference numerals 101 to 118 denote steps in FIG.
Reference numerals 0 to 216 represent steps in FIG.
Reference numeral 315 indicates each step in FIG.

Referring first to FIG. FIG. 2 shows an embodiment according to the first and second aspects of the present invention. That is, prior to the activation of the split-budget mode, a unit deduction amount A to be withdrawn from the card in one process via the keyboard 5 is input and stored as a set value (101). And split bill mode start switch 7
While the start-up operation is not performed, the normal balance processing is executed (repetition of 102, branch N → 105 → 102, branch N). If it is determined that the switch 7 has activated the split billing mode (102, branch N), the merchandise (sales) price B for the split billing process is input via the keyboard 5 (10).
3) The price B is stored as the unpaid amount C (10
4). Then, "Every time a card is inserted, the unit balance A is deducted from the card balance D and a new balance E is written to the card and returned. At the same time, the unit balance A is deducted from the unpaid amount C. The unpaid amount is C. Is repeated until the unpaid amount C becomes 0 or becomes less than the unit subtraction amount A (106-108 → 109 → 111-115).
→ Repetition of 106). When the unpaid amount C becomes 0, the split billing process ends (112, branch Y).

However, if the unpaid amount C is smaller than the unit deduction A and is not 0, a new balance E obtained by subtracting the unpaid amount C from the card balance D is written back to the card and returned. End splitting processing (106-108 → 10
9 (or 106-108 → 110 → 109) → 116-
118).

Next, FIG. 3 will be described. FIG. 3 shows an embodiment of the invention according to the first and third aspects. In this embodiment, the number G of split bills (accordingly, the number of cards to be split, here referred to as the number of split bills) G is set in advance. That is, after the split-budget mode activation by the switch 7 is determined (200, branch Y), the merchandise prices B and the number of divisions G (that is, the number of split bills) for B are input via the keyboard 5 (202, 203). Then, by inputting this G, the amount deducted at one time (unit deduction amount)
A = B / G and a fraction corrected subtraction amount A1 = A + (remainder) obtained by adding the fraction of the division B / G to the sum A are calculated (2).
04, 205).

Each time the card is inserted, the operation of writing a new balance E, which is obtained by subtracting the unit subtraction amount A from the card balance D, into the card and returning the same, is repeated G-1 times (206 to 213 → 206) and the last (G-th) card insertion, the fractional correction subtraction amount A1
By writing a new balance E, which is obtained by subtracting from the above, into this card, the split billing process is completed (206 to 210 → 2
14-216).

[0014]

According to the present invention, a function of dividing a common sales amount of a card terminal into a plurality of (a plurality of) prepaid cards and withdrawing the same is added, so that the card user is pleased. Card system can be provided.
