[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]

 Recently, magnetic cards have become popular as prepaid cards. It is characterized by recording a large amount of data and keeping the data confidential. However, since a magnetic card normally writes data to a magnetic stripe attached to a resin and then reads it magnetically, it is extremely easy to falsify or tamper with a magnetic writer. Therefore, it causes various problems.

For this reason, mainly for the purpose of data tampering and fraud prevention, the balance is printed and displayed as a binary code on the surface of a paper or plastic card as a binary data, and the display is updated each time the balance is updated. Prepaid cards have come to be used. Such a prepaid card is generally manufactured by printing on the surface of the prepaid card, first, a limit amount, that is, a binary number display of the balance at the time of issuing the prepaid card, with a corresponding series of black circles and spaces. Each time the prepaid card is used, the updated prepaid card reader / writer additionally prints the updated balance on the card in a line consisting of black circles and spaces.

[0004]

[Problems to be solved by the device]

 As described above, generally, in the case of a prepaid card, when reading from the card, the card reader sequentially searches the card surface to find the most recently updated balance record, and reads and processes it. However, in the conventional prepaid card as described above, all the data strings are printed and displayed on one side of the prepaid card. Therefore, there is a drawback that the data access speed is slow. Another problem is that the prepaid card has a small recording capacity. In addition, in the write-once printing, since the head is moved using the data string previously written by the prepaid card reader / writer as a guide, the error between the printing position and the angle is accumulated and inherited.

The present invention has been made in order to solve the problems of the prior art, and its purpose is to have a high data reading rate and a large recording capacity, and to accumulate errors during access. To provide a reliable prepaid card that does not have.

[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 the prepaid card that prints and displays the newest print display each time the data is updated, the gray print mark is added to the old print display, and the data is divided into two, and the front surface of the prepaid card is displayed. One of the divided data is printed in rows, the other of the divided data is printed in rows on the back side, and the data printed in each row is displayed in advance in one row on the surface. It is characterized by being printed adjacent to the test data.

[0007]

[Action]

 In the prepaid card of the present invention configured as described above, one data is divided into two, one of the divided data is on the front surface of the prepaid card, and the other divided data is on the back surface. Since they are distributed and printed, both prints can be read at the same time. As a result, the data access speed is improved. Furthermore, since the printing area is expanded, the recording capacity of the entire prepaid card is increased.

In addition, when the prepaid card reader / writer accesses the prepaid card of the present invention, the test data string displayed in advance in a row is first detected, and the access position and angle are adjusted by the test data string. , The adjacent data string is read, and the test data string is first detected when printing the data, so that the position error and the angle error caused by the writing by the different card reader / writer are accumulated at each access. Is not inherited by the printing of. As a result, error occurrence is eliminated.

【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.

Further, on the front surface and the back surface, a plurality of test data formed by T11 to V11 or T12 to V12 and the like are displayed in a line in parallel with the short side 1C. . V11 and V12 are parity bits. The recorded data, for example, the limit amount data recorded when the prepaid card 1 is issued is composed of eight bits D11 to D18. This data is divided into two, one set consisting of D11, D13, D15 and D17 and one set consisting of D12, D14, D16 and D18, and one parity bit P11 and P12 is added respectively.

One set of D11, D13, D15, D17 and P11, for example, is adjacent to the test data T11 to V11 on the front surface 1A of the prepaid card 1 and is parallel to the short side 1C. Are printed in rows as a series of black and white circles lined up in. Further, one set of D12, D14, D16, D18 and P12 is a series of black circles adjacent to the test data T12 to V12 on the back surface 1B of the prepaid card 1 and arranged in parallel with the short side 1C. It is printed in rows as white circles. That is, the limit amount data composed of 8 bits D11 to D18 is divided into two sets each composed of 4 bits, and is divided into the front side and the back side 1B of the prepaid card 1, respectively. , Manufactured by being distributed and printed adjacent to the test data.

When the prepaid card 1 manufactured as described above is used, when the payment procedure is performed, the updated balance data including, for example, D21 to D24 is divided into two, One set is composed of D21, D23, etc., and another set is composed of D22, D24, etc. One parity bit is added to each. One set consisting of D21, D23, etc. is a series of black circles and white circles arranged in parallel on the front side 1A of the prepaid card 1 parallel to the short side 1C, and D11, D13, D15, D17, P11 previously printed And printed adjacent to the test data consisting of T21 to T23. Further, one set of D22, D24, etc. is formed on the back surface 1B of the prepaid card 1 as a series of black circles and white circles arranged in parallel with the short side 1C, and the previously printed D12, D14, D16. , D18, and P12, and are printed adjacent to the test data including T22 to T24. After that, each time data is updated, the updated data is distributed and added in the same manner as described above.

In addition, in the present embodiment, the data string consisting of the data D11 to D17 printed on the front surface and the data string consisting of D12 to D18 printed on the back surface are the short lengths of the prepaid card 1. Although it is provided in parallel to the side 1C, it is not limited to this configuration, and may be provided in parallel to the long side 1E, for example.

In general, the data display corresponds to a binary number with a black mark and a blank. 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.
