Abstract

PURPOSE: To prevent an illegal card from being used by overwriting and painting out the whole recording part of read data each time the data are read and their processing result is recorded in a next area on a card, and judging that the card is used if the part is painted out when the card is read. CONSTITUTION: When the card 1 is used, a read collation process for read data 2 is performed. This process is performed by reading the read data from an initial code area 1a in order by a head and confirming whether or not it is painted out. Consequently, it is decided that the card is already used when the read data 2 corresponding to the initial code area 1a are already painted in black although the card appears to be an unused card having no record in the balance code area as data 3 after the process, and it is decided that the card is evidently an illegal card obtained by sticking an upper and a lower card on each other and inhibited from being used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, for example, uses a prepaid card or the like constituted by a code card in which information is written with a four-segment one-dimensional or two-dimensional graphic code,
The present invention relates to a code card system that performs various commercial activities.

[0002]

2. Description of the Related Art In a conventional card system such as a prepaid card system, a two-dimensional code card 40 as in the conventional card example shown in FIG. 3 is used. Here, 40a is an initial setting code area that is information that is initially set and includes the amount of money, 40b is a balance code area that is information that includes the amount of money used, and 40c is a display character area for the user. Information such as the initial code area 40a of the two-dimensional code card 40 shown in FIG. 3 is written by a two-dimensional graphic code called a 4-segment Carla code (registered trademark of Alec Japan). In this Carla code, for example, four segments obtained by dividing a quadrangle into four are used as one basic code, and a black segment that is filled and marked and a white segment that is not marked are associated with information "1" and "0", respectively. Various kinds of information are displayed by combination, and the amount of information becomes large as compared with a bar code or the like, and there are advantages that direct computer processing is possible.

FIG. 4 is a schematic block diagram of a conventional system ticket issuing machine. When a bill is inserted into the ticket issuing machine as shown in FIG. 4 from the customer side, the ticket issuing machine first reads the key code of the transparent ink printed portion of the prepaid card to be issued by the optical reading sensor 50 and then sends it by the roller A. In the initial code area on the card 40, a writing head 51 composed of a heat-sensitive 7-needle head or the like reciprocally scans at a predetermined speed in a direction orthogonal to the traveling direction of the card, thereby performing a thermal recording. Write the numerical information of the code, etc. For example, when the 10,000 yen button is pressed, 10,000 yen numerical information and the like are written in the initial code area of the prepaid card 40 as shown in FIG.

Prepaid card 40 for which writing has been completed
The optical read head 52 for verification (verification) confirms the written contents of the black and white segment by the Carla code, and if there is no error, the roller B sends the card 40 to the customer.

FIG. 5 is a schematic block diagram of a card reader of a conventional system. Issued prepaid card 40
When using the card, insert the card 40 into the card reader and enter the amount of money from the fee input section 60. The CPU 61 reads the remaining amount in the code area of the inserted prepaid card 40 with the reading head 63, and the remaining amount is sufficient. After confirming that there is a key code and confirming that there is a corresponding product (amusement,
At the same time as instructing the release of a ticket or goods, a new balance (for example, 8,000 yen) is written in the balance code area 40b of the prepaid card 40 by the write head 62 and sent back to the customer.

[0006]

However, in the above-described conventional system, the confirmation of the remaining amount of the two-dimensional code card 40 and the rewriting process are performed relatively reliably.
Due to insufficient consideration of the fraudulent card discrimination processing, the initial code area part (10,000 yen) of the card which has been used several times as shown in FIG. There is a problem in that fraudulent card creation is used by utilizing the fact that a small-value card is recognized by a card reader as if it were a high-value card by pasting the balance code areas of the cards together.

[0007] Therefore, an object of the present invention is to provide a two-dimensional code card system which can prevent the use of an illegal card using the initial code area of the two-dimensional code card (the area for writing the card amount).

[0008]

In order to achieve the above-mentioned object, the present invention sets N segments (N is an integer of 2 or more) to 1
An initial setting code area, which is information including the amount of money initially set for writing predetermined numbers, characters, etc., represented by a figure code as unit data by the card writing means, and information including the amount of money used. In a code card system which reads a code card having a certain balance code area by a card reading means and executes a process by judging an instruction content inputted by a user, necessary data is read and a processing result is recorded in a next area. Each time, it has a code card in which the entire recorded portion of the read data is overwritten and filled, and a card reading means which confirms the data recording area when reading the card and judges that it is a used card and does not use it. It is characterized by

[0009]

According to the above structure, the necessary data of the two-dimensional code card is read and processed, and every time the data is recorded in the next area on the card, the entire recorded portion of the read data is overwritten and filled. When reading the card, the card reading means checks the data recording area and judges that it is a used card if it is filled, so it is sure that an illegal card in which the initial code area and the remaining area of other unused cards are pasted Can be detected as a fraudulent card.

[0010]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing a two-dimensional code card 1 according to an embodiment of the present invention. The two-dimensional code card 1 is divided into an initial code area 1a and a balance code area 1b as shown in the figure. FIG. 1 (a) shows a card that has just been issued from a ticket issuing machine in an initial state and has not been used yet, and FIG. 1 (b) shows a state in which the remaining money code information 3 is recorded after being used once.

In the two-dimensional code card 1 of the present embodiment shown in FIG. 1, necessary read data is read (read) from, for example, the initial code area 1a in FIG. 1 is written in the balance code area 1b as shown in FIG. 1 (b). When writing to the next area on the card 1, the previous read data is always filled so that it cannot be reused. In the case of FIG. 1B, the initial code area 1a is painted.

Therefore, even if the amount code of 10,000 yen is written in the initial code area 1a, if it is used once and the amount code of 8,000 yen of the processing result is written in the balance code area 1b, for example, At the same time, the previous 10,000 yen record has been completely filled and erased, making it impossible to reuse for illegal purposes. Next, at the time of the second use, since the data 3 after processing is further painted, a total of two data will be painted.

FIG. 2 is a schematic block diagram of a card reader of a system according to an embodiment of the present invention. The card reader of the present embodiment shown in FIG. 2 is different from the conventional card reader shown in FIG. 5 in that a matching unit 4 for matching data 3 of the card under CPU control is provided. It has the same structure as the card reader of No. 5.

Next, the operation will be described. When a banknote is inserted into the system ticket issuing machine shown in FIG. 4 as in the conventional case, the ticket issuing machine side reads the key code by the transparent ink printing, and then writes the thermal recording head 51 in the initial code area 1a of the card 1.
By this, the money amount information and the like of the two-dimensional code is written.

Here, the write head 5 for writing the amount information in the initial code area 1a and filling the read data 2 is used.
For information writing by 1, for example, one segment is 7 × 5
As a dot display, if a heat-sensitive 7-needle head with a 0.2 mm interval that moves in a direction orthogonal to the card movement (horizontal direction) at a predetermined speed is used as the writing head 51, 5 segments (longitudinal direction) will write 1 segment Black out "1" by painting 7x5 dots
Obtaining a display If you do not write in one segment, you can get a white "0" display, and write the amount of money, etc., you can display a code by using these combinations. It will be filled by writing. In the prepaid card used for the first time, the initial code information is filled in, and from the second time, the remaining balance code information immediately before is filled in sequentially. In this way, the two-dimensional code card 1 for which writing has been completed is coated on after confirming the written contents and sent to the customer.

When the card 1 thus issued is used, it is inserted into the card reader shown in FIG.
If you enter the amount from 0, the CPU 61 on the card reader side
After confirming the remaining amount of the card, the key code, etc., reads out the read data 2 through the collation unit 4 and performs collation processing. In the collation process, first, the read data is sequentially read from the initial code area 1a by the read head 63 and it is confirmed whether or not the read data is filled. The reading head 63 is, for example, of a type in which a slit of 0.5 mm is moved on the graphic code in the direction orthogonal to the card movement and the reflected light of the projected light is received by an optical sensor to read black and white. It may be configured by a transmitted light receiving type, an area sensor such as a line sensor, or a CCD.

As a result of the matching process, the read data 2 corresponding to the initial code area 1a has already been painted in all black even though the remaining code area is not recorded as the processed data 3 and the card is still unused. In such a case, it is determined that the card has been used, and it is clearly prohibited from being used because it is a fraudulent card in which upper and lower separate cards are pasted together.

[0018]

As described above, according to the code card system of the present invention, every time the necessary data is read and the processing result is recorded in the next area, the entire recorded portion of the previously read data is overwritten. And then fill in the code card,
When reading a card, check the data recording area and if it is filled, it is judged as a used card and does not use it. As compared with the old system, which requires a complicated fraud prevention system as a countermeasure because it has advanced, this system has an extremely simple configuration and fraudulent cards such as bonding using the initial code area etc. The effect is that the use of can be reliably prevented.
