[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 problem that the data access error cannot be detected. In addition, since the head is moved by using the data string written by the prepaid card reader / writer as a guide in the previous write-once printing, there is a drawback in that printing position errors and angle errors are accumulated and inherited during subsequent printing. It was

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 read rate, to enable detection of a data read error, and to access the data. The aim is to provide a highly reliable prepaid card that does not accumulate time 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 the latest print display each time data is updated, using a row of dark and light colored markings to print on the old print display, the front and back surfaces of the prepaid card are marked with a gray mark. Multiple rows of test data are pre-displayed at equal intervals, and the rows of test data on the front surface are positioned at a predetermined distance from the rows of test data on the back surface. The data is displayed in a staggered manner, the data is printed in rows on the front side, the same data is printed in rows on the back side, and the data printed in rows is pre-printed in a row on each side. Is displayed in Characterized in that it is printed adjacent to the serial test data.

[0007]

[Action]

 In the prepaid card of the present invention configured as described above, one piece of data is printed overlappingly on the front side and the front side, so the prepaid card reader / writer accesses the prepaid card of the present invention. At this time, the access error is verified by reading out both prints and comparing them. Furthermore, because the positions of the data strings printed on the front and back sides are offset, the time required to move the read / write head when accessing with the prepaid card reader / writer is saved, and thus read during continuous access. The time is minimal.

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 pieces of test data formed in a line in parallel with the short side 1C such as T11 to T15 or T21 to T25 are displayed in advance. . Data marks, which will be described later, will be printed on the rear side of the card adjacent to the test data on each surface. Therefore, the data mark is printed between the two test data. The distance between the two pieces of test data is equidistant on both the front and back surfaces.

Moreover, for example, the distance d1 from the short side 1C which is the front end of the card to the row of T11 to T15 on the front surface, and the distance d2 from the short side 1C to the row of T21 to T25 on the back surface. Are provided with a difference. This distance difference is set according to the size of the read / write head of the prepaid card reader / writer so that continuous access is possible with the minimum movement of the read / write head.

The recorded data, for example, the limit amount data recorded when the prepaid card 1 is issued is composed of 10 bits D11 to D20. The limit amount data is a series of black circles and spaces arranged in parallel with the short side 1C adjacent to the test data T11 to T20 on the front side 1A of the prepaid card 1 and extends from the long side 1F to the long side. It is printed toward 1E. Further, the same limit amount data is 10 bits of B11 to B20, and on the back surface 1B of the prepaid card 1, as a series of black circles and spaces arranged parallel to the short side 1C, from the long side 1F to the long side 1E. Printed face-to-face. That is, the 10 bits of the limit amount data are overprinted on the front surface 1A and the back surface 1B of the prepaid card 1, respectively, and the prepaid card 1 is manufactured.

When the prepaid card 1 manufactured as described above is used, when the payment procedure is performed, the data D11 to D20 and the data B11 from the front surface 1A and the back surface 1B are recorded. ~ B20 are read out and compared with each other. If both read data match, it is regarded as the limit amount data, but if they do not match, it can be considered as an access error or a previous printing error and countermeasures can be taken. The updated balances are printed on the front and back sides, respectively, next to the test data, side by side with the old balances. After that, each time data is updated, the updated data is distributed and added in the same manner as described above.

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. In addition, in this embodiment, the data string consisting of the data D11 to D20 printed on the front surface and the data string consisting of the data B11 to B20 printed on the back surface are the short sides of the prepaid card 1. Although it is provided in parallel with 1C, it is not limited to this configuration and can be provided, for example, in parallel with the long side 1E.

In general, 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.

[Effect of device]

 As described above, in the prepaid card of the present invention, one data is printed on the back side and the front side in an overlapping manner. To be verified. As a result, reliability at the access stage is improved, and thus a more reliable prepaid card can be realized. In addition, because the data lines printed on the front and back sides are arranged at different positions, the time required to move the read / write head when accessing with the prepaid card reader / writer can be saved, thus reducing the access lead time. It can be minimized.

Further, since the test data is preliminarily displayed in a row on the front surface and the back surface of the prepaid card, the card reader / writer first detects the test data row each time it is accessed, and the access position and After adjusting the angle, the adjacent print data string is read out, and when recording the data, the test data string is first detected and then printed adjacent to each other.Therefore, writing with different card reader / writers is performed at each access. Positional errors and angular errors that occur as a result are not accumulated or inherited in later records. Therefore, it is possible to realize a highly reliable prepaid card, and there is a great effect on the industry.
