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]

 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 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. It is displayed in a staggered manner, and the data is further divided into two, one of the divided data is printed in a row adjacent to the test data on the front side, and the other divided data is the test data on the back side. And wherein the printed in rows adjacently.

[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. 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, first, a test data string displayed 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 row in parallel with the short side 1C, such as T11 to V11 or T12 to V12, are displayed in advance. ing. V11 and V12 are parity bits. A mark of data, which will be described later, is 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 distances between the two test data are equidistant on both the front and back surfaces.

Moreover, for example, the distance from the short side 1C that is the front end of the card to the row of T11 to V11 on the front surface and the distance from the short side 1C to the row of T12 to V12 on the back surface are: There is a distance 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 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, for example D11, D13, D15, D17, P11, 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. It is printed in rows as a series of lined black circles and spaces. Further, one set of D12, D14, D16, D18 and P12 is a series of black circles that are adjacent to the test data T12 to V12 on the back surface 1B of the prepaid card 1 and are parallel to the short side 1C. It is printed in rows as spaces. That is, the limit amount data composed of 8 bits D11 to D18 is divided into two sets each composed of 4 bits, and the front side and the back side 1B of the prepaid card 1 are respectively tested. It is manufactured by being distributed and printed adjacent to the 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 consisting 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.

Further, 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. However, the present invention is not limited to this, and any combination of dark and light colors can be applied.

[0017]

[Effect of device]

 As described above, in the prepaid card of the present invention, one piece of data is divided into two, the front side of the prepaid card is the one divided, and the back side is the other divided. Both prints can be read at the same time because they are distributed and printed. 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.

Furthermore, since the test data is configured to be displayed in a row in advance on the front and back sides of the prepaid card, the card reader / writer first detects the test data row each time the access is made, 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.

As a result, it becomes possible to realize a prepaid card which has a high data read rate, a large recording capacity, can eliminate the occurrence of an access error, and is highly reliable, and therefore has a great industrial effect. There is.
