Abstract

(57) [Summary] [Purpose] To provide a prepaid card capable of detecting a data access error. [Structure] Each bit of data D1 to D5 composed of binary numbers is printed and displayed on the card surface by a dark color mark on one side of "0" and "1" and a light color mark on the other side. However, in the prepaid card in which the latest print display is additionally printed on the old print display by a row of dark and light color marks each time the data is updated, the data D1 to D5 has a specific length on the front surface of the prepaid card. Data is printed parallel to the short side 1C from the side 1F to the other long side 1E.
The same data as 1 ~ D5 is B1 ~ B5, on the back side,
Short side 1 from a specific long side 1F to another long side 1E
Printing is performed in parallel with C by shifting a predetermined distance from the printing position on the front surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a prepaid card, and more particularly to a prepaid card in which data is displayed on a card surface by a combination of a dark color mark and a light color mark.

[0002]

[Prior art]

 Conventionally, for the purpose of preventing data tampering and fraud, a prepaid card with a structure in which the balance is printed and displayed as a binary data with a gray mark on the surface of a paper or plastic card and the display is updated each time the balance is updated is used. Has reached the end. Such prepaid cards are generally printed on the surface of the prepaid card with the maximum amount, that is, the binary representation of the balance at the time of issuing the prepaid card, as a corresponding series of black circles and space data. Manufactured. Then, each time the prepaid card is used, the updated balance is additionally printed on the card by a data string consisting of black circles and spaces. Furthermore, in order to increase the recording capacity per prepaid card, a structure in which printing and recording are performed on both front and back surfaces has been attempted.

[0004]

[Problems to be solved by the device]

 In the read / write head of the prepaid card reader / writer for accessing the prepaid card printed on both sides as described above, the optical sensor R D1 that reads from the front surface of the card and the inkjet printer WR1 that prints on the front surface of the card are only at the distance L1. The optical sensor RD2 is arranged at the same position as the optical sensor RD1 and is arranged so as to interlock with the prepaid card, and the optical sensor RD2 is interlocked with the optical sensor RD1. It has become. Similarly, an inkjet printer WR2 that prints on the back side of the card with the prepaid card in between is arranged at the same position as the inkjet printer WR1, and the inkjet printer WR2 is configured to interlock with the inkjet printer WR1.

Therefore, if the distance between the two data strings ds1 and ds2 on the front and back of the prepaid card is L2, which is larger than the distance L1 between the optical sensor RD1 and the inkjet printer WR1, the inkjet printer WR1 will detect the data string. The position of the optical sensor RD1 when printing on ds1 is separated from the position of the data string ds2 by the difference between L2 and L1. To access the data string ds2 continuously, the entire read / write head is separated by the distance between the difference of L2 and L1. It had to be moved, which resulted in a large access lead time, which was time consuming.

The present invention has been made in order to solve the problems of the prior art, and its purpose is to omit the read / write head movement in continuous read / write to minimize the access read time, and thus the data read rate. The purpose of the present invention is to provide a prepaid card which can be applied to a prepaid card reader / writer having a function of detecting a data access error.

[0006]

[Means for Solving the Problems]

 The prepaid card of the present invention uses a dark color mark on either side of "0" or "1" and a light color mark on the other side of each bit of the data composed of binary numbers to display on the card surface. In a prepaid card that prints and displays, and each time the data is updated, the latest print display is added to the old print display by a row of dark and light colored marks, and the data is printed on the front surface of the prepaid card with a specified length. Printed parallel to the short side from the long side to the other long side, and the same data as the above data is printed on the back surface, parallel to the short side from the specific long side to the other long side, and It is characterized in that the printing is performed by deviating from the printing position on the front surface by a predetermined distance.

[0007]

[Action]

 In the prepaid card of the present invention configured as described above, since data is printed on both sides of the back face, continuous access can be performed without moving the read / write head when accessed by the prepaid card reader / writer. . As a result, data access speed is improved. Further, since one data is printed on both the back side and the front side in duplicate, an access error is detected by reading out and comparing both prints.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. The prepaid card 1 of the present invention has a pair of short sides 1C, 1D and long sides 1E, 1F, respectively, and is printed on both the front side 1A of the prepaid card 1 and the back side 1B of the card. It is configured to be possible. A slit S for identifying the front / back / front and back of the card is provided near the short side 1C of the long side 1E. The data to be recorded, for example the limit amount data, is composed of 5 bits D1 to D5.

The limit amount data D1 to D5 are placed on the front side 1A of the prepaid card 1 at a distance d1 from the short side 1C, which is the beginning of the card, and from the long side 1F to the other long side 1E. Print as a series of black circles and spaces facing each other and parallel to the short side 1C. Further, the limit amount data D1 to D5 are set as data B1 to B5 at a position of a distance d2 from the short side 1C, which is the head of the card, on the back side 1B of the prepaid card 1, and from the long side 1F to another long side. It prints as a series of black circles and spaces that are aligned in parallel with the short side 1C toward the side 1E. That is, the limit amount data composed of 5 bits D1 to D5 are overlapped and printed on the front side 1A and the back side 1B of the prepaid card 1 by shifting by the difference between the distances d2 and d1.

When the prepaid card 1 manufactured as described above is used, the data D1 to D5 and the data B1 to B5 from the front surface 1A and the back surface 1B are used when the payment procedure is performed. Are read out and compared. If both the read data match, it is considered as the limit amount data, but if they do not match, it can be considered as an access error or a printing error before and a countermeasure can be taken. The updated balance is printed as data D6 to D10 and data B6 to B10 on the front surface and the back surface side by side with the old balance.

As described above, each print row on the front surface and the corresponding print row on the back surface are always displaced by the difference between the distances d2 and d1. By making this deviation equal to the difference between the distance between the data strings and the distance between the optical sensor in the read / write head and the inkjet printer, the read / write head movement time is saved and the access lead time is minimized. it can.

Generally, the data display is represented by a black mark and a blank in binary correspondence. That is, the black mark is either "0" or "1", and the blank part is either "1" or "0". In the above embodiment, the dark color mark is black and the light color mark is printed in white on the surface of the card. However, the present invention is not limited to this, and any combination of dark and light colors can be applied.

[0013]

[Effect of device]

 As described above, the prepaid card of the present invention has a structure in which one data is printed on the back side and the front side in an overlapping manner. Can be detected. As a result, the reliability at the access stage is improved, and a more reliable prepaid card can be realized. In addition, the time required to move the read / write head when accessing with the prepaid card reader / writer can be saved, and the access lead time can be minimized, and a system with good usability can be constructed.
