Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a coupon ticket system in which a part of information is erased and the remaining amount of coupons is reduced each time the coupon ticket is used for shopping.

[Conventional technology]

A conventional card recording is shown in FIG. In FIG. 3, 1 is a magnetic layer, 2 is a plastic card substrate, and a1
˜a100 are 100 bursts recorded in the magnetic layer 1. FIG. 4 is an enlarged view of the burst. In this conventional example, the unit class of each burst is 10 yen, so the amount when not in use, that is, when not in use, is 10 yen x 100 = 1
It is 000 yen. That is, the user can use this card for 100
It will be purchased for 0 yen. When using this card for 50 yen, for example, bursts a1 to a5 of magnetic layer 1 are erased, the remaining bursts are a6 to a100, and the balance is 95
It will be 0 yen.

FIG. 2 is a perspective view showing a general example of reproducing / erasing recorded data on a card. In FIG. 2, 3 is a reproducing head and 4 is an erasing head. The recorded data on the card is reproduced and displayed by the reproducing head 3. The user is
Confirm the information such as the balance by looking at the display. Further, numerical values such as the amount used are erased by the erasing head 4.

[Problems to be solved by the invention]

Thus, in the conventional card system of this type, the unit amount of information to be erased was one type of 10 yen. Since the unit amount is small, it is possible to make fine adjustments, but if the unused card remaining amount is high, the number of bursts will increase and it may not be possible to record in the recording area of the card with a certain limit. It was Also, if the unit price is increased, a high-priced card can be easily obtained, but there is a problem that it is impossible to make a very fine payment.

[Means for solving problems]

In order to solve such a problem, according to the present invention, information about the amount (X) of an unused coupon is at least high-value information (the unit amount is Y).
far. ) And a low-price information corresponding to the minimum settlement unit (the unit amount is denoted by Z) and recorded on the magnetic layer of the card in two types, and the unit amount of the high-price information and the low-price information. Is Y = n × Z (n is an integer), the number of bursts of high-value information (denoted as M) is M ≦ X /
It is a maximum integer that satisfies [Y + (n-1) × Z].

[Action]

In the present invention, the limited recording area of the card can be effectively utilized, and even if the amount of shopping or the like becomes expensive, it is possible to perform highly accurate and easy fine settlement.

〔Example〕

FIG. 1 is a schematic sectional view of a card structure for explaining an embodiment of a coupon card system according to the present invention. First
In the figure, 1 is a magnetic layer having a coercive force of 1.5 kOe or more, 2 is a plastic card substrate, b1 to b5 are bursts indicating high-value information such as the remaining amount of coupons (hereinafter referred to as "high-value information burst"), a1 to a50 Is a burst indicating low-value information such as the remaining amount of the coupon (hereinafter referred to as "low-value information burst"). Information consisting of a plurality of bursts in the magnetic layer 1 is reproduced by the reproducing magnetic head 3 as shown in FIG. 2, and part of the information is erased by the erasing magnetic head 4. The reproducing magnetic head 3 has a saturation magnetic flux density of, for example, N of 3 kG or less.
Since iZn ferrite is used for the magnetic core, recording cannot be performed on the magnetic layer with a coercive force of 1.5 kOe or more. Further, the erasing magnetic head 4 is a magnetic head in which recording is not possible by processing the tip of the magnetic core into an arc shape.

Next, recording / erasing of information in this method will be described. First, use it for shopping for juice etc.
As a magnetic card for 100 yen shopping coupons, 5 high-value information bursts with a unit price of 100 yen equivalent to the minimum purchase price
We record 50 low-priced information bursts with a minimum unit of 10 yen for settlement, and make a magnetic card whose unused amount is 1000 yen. Here, the reason why there are five high-priced information bursts with a unit price of 100 yen is to prevent the high-priced information bursts from being left behind. The reason why there is no leftover when shopping over 100 yen is explained below.

If there is 10 yen remaining on the previous card and you buy 100 yen using the next card after the previous one, 9 low-priced information bursts with a unit price of 10 yen will be erased from the next card. . For example, the low-priced information bursts a1 to a9 are deleted. After that, if you make a purchase of 190 yen four times, four high-value information bursts and 36 low-value information bursts will be erased. For example, the high-value information bursts b1 to b4 and the low-value information bursts a10 to a45 are deleted. In this case, the remaining unit amount that is not erased is 10
The high-priced information burst of 0 yen is one of b5, and the low-priced information burst of 10 yen that remains without being erased is a46 to a50.
It is five of. Next, if you shop for more than 100 yen with this card, no high-value information will remain, so even if you use cards one after another, only high-value information will not remain.

Next, the above description will be described by using mathematical expressions. Letting X be the amount of unused coupons, Y and Z be the high-price information and low-price information to be erased, respectively, X = 1000 (yen) Y = 100 (yen) Z = 10 (yen) n = Y / Z = 10. Here, consider a case where the low-priced information burst is the smallest. The remaining amount of the previous card is the minimum remaining amount (one low-value information burst), and when the next card is used for shopping, the remaining amount of the next card becomes X- (n-1) * Z.

On the other hand, when the number of high-priced information bursts is M, the usage amount when one high-priced information burst is left and the low-priced information burst is erased most is (M−1) × {Y + (n− 1) × Z}, and therefore the balance is X− (n−1) × Z− (M−1) × {Y + (n−1) ×
Z}.

At this point, one high-priced information burst remains, and if the remaining amount is Y or more, this high-priced burst information is erased at the time of the next purchase, and only the high-priced information does not remain. Therefore, Y ≦ X− (n−1) × Z− (M−1) × {Y + (n−
1) × Z} (M−1) ≦ {X−Y− (n−1) × Z} / {Y + (n
−1) × Z} M ≦ [{X−Y− (n−1) × Z} / {Y + (n−1)
× Z}] + 1, M ≦ X / {Y + (n−1) × Z}, and therefore M ≦ X / {Y + (n−1) × Z} = 1000/190 = 5.26 The maximum integer is M = 5.

In this embodiment, the total number of high-priced information bursts and low-priced information bursts is 55. On the other hand, the burst in the conventional method shown in FIG. 3 is a low-priced information burst, and the number thereof is 100. As described above, in this embodiment, since the burst recording area is small and the burst erasing number is small, the reliability can be improved accordingly. In addition, since the unit price of the low-price information is 10 yen, even if the recording area of the burst is limited, it is possible to easily carry out finer adjustments for high-priced shopping.

Although the magnetic card has been described above, the present invention can be similarly applied to a hologram card in which information is reproduced / erased by a laser or the like.

Even if an attempt is made to record a high-priced information burst and a low-priced information burst using the reproducing magnetic head 3 and the erasing magnetic head 4 for the purpose of illegal use of the card, these heads are recorded on the magnetic layer of the card as described above. Since it is not capable of playing cards, it is possible to reliably prevent counterfeiting of cards.

〔The invention's effect〕

As described above, according to the present invention, the information regarding the amount of the unused coupons is divided into at least a burst indicating the high-priced information corresponding to the minimum purchase unit and the low-price information corresponding to the minimum payment unit divided into two types of cards. Since it is recorded on the magnetic layer of the card, the limited recording area of the card can be effectively utilized, and even if the amount of money for shopping is high, the number of bursts to be erased is small, and the texture is highly reliable. This has the effect of making it possible to easily make detailed payments.
