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 has a certain feature in that it records a large amount of data and keeps the confidentiality of the data. 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 tamper with data by a magnetic writer and thus make it illegal. Is causing 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. An example of such a prepaid card is shown in FIG.

In FIG. 1, the prepaid card 10 having a pair of long sides and short sides each has a print area on the front surface 10 A, and the recorded data in binary display is a predetermined area within the print area with a series of black and white circles. It is printed at the position. The white circle is the same as the surface color of the prepaid card 10 and is therefore displayed as a space. When the prepaid card 10 is used, when the payment procedure is performed, the card reader / writer updates the balance data D51 to D55, for example, in the printing area of the prepaid card 10 in the short side direction with a black circle and a space. It is printed in a column consisting of. Hereafter, each time the prepaid card 10 is used, the latest balance, for example, D51 to D55 is read from the prepaid card 10, and the updated balances D56 to D60 are added to the old balances D51 to D55 in a row consisting of black circles and spaces. It is something.

[0005]

[Problems to be solved by the device]

 With the conventional prepaid card as described above, when reading from the card, the card reader sequentially searches the card surface, finds the most recently updated balance record with black circles, reads it, and processes it. To do. In addition, when writing on the card, the card writer will sequentially search the card surface to find the most recently updated balance record with a black circle and write it side by side. However, the recording position and angle of the data string vary depending on each card reader / writer. Therefore, if the card reader / writer does not adjust the recording position or angle normally and prints out of the specified recording position or angle, it may adversely affect the position or angle of subsequent data recording. Therefore, there is a risk that it will interfere with the correct balance processing, which is not preferable.

The present invention has been made in order to solve the problem of the prior art, and the purpose thereof is to easily detect a data read position and a data write position without causing an error in an access position. It is to provide a highly reliable prepaid card.

[0007]

[Means for Solving the Problems]

 The prepaid card of the present invention uses a dark mark on either side of "0" or "1" and a light mark on the other side for each bit of the data composed of binary numbers, and it is displayed on the card surface. In a prepaid card with a print area that prints and displays as a data string, and each time the data is updated, the latest display is printed with a dark and light colored data string and is added to the old display. The test data is displayed in a line in advance.

[0008]

[Action]

 In the prepaid card of the present invention configured as described above, the card reader / writer first detects a test data string displayed in a line in advance each time it is accessed, and adjusts the access position and angle by the test data string. At this point, the recorded data string consisting of adjacent display marks is read, and the test data string is also detected first when data is recorded.Therefore, position error and angular error caused by writing by different card reader / writers at each access. Are not accumulated or inherited in later records. As a result, error occurrence is eliminated.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIG. In the prepaid card 1 of the present invention, predetermined test data T1 to T5, T6 to T10, etc. are preliminarily displayed in a line between the positions on the front surface 1A of the card where the data sequence is to be printed and displayed. There is. In the figure, each test data is constituted by a cross mark, but each test data need only be one that can be distinguished from the data string, and its shape and dimensions are not particularly specified. In addition, in this embodiment, the test data T1 to T5 and T6 to T10 as well as the data string R1 composed of D1 to D5 and the data string R2 composed of D6 to D10 described later are parallel to the short side 1C of the prepaid card 1. However, the present invention is not limited to this configuration, and may be provided in parallel with the long side 1E, for example.

Between the test data T1 to T5 and the test data T6 to T10 which are displayed in a line in advance and adjacent to the test data T1, there is data composed of a binary value, for example, for each bit, "1". The "" side is printed and displayed as dark-colored marks D1, D4, D5, and the "0" side is printed and displayed as a data string R1 composed of light-colored marks D2, D3.

In the next recording, the card reader / writer first detects the test data strings T6 to T10 previously displayed in a line, adjusts the access position and angle by the test data strings T6 to T10, and then, The recording data string R2 consisting of adjacent display marks is read out, and the test data strings T6 to T10 are detected first even when data is recorded. Therefore, a position error caused by writing by a different card reader / writer at each access or Angular error will not accumulate and will not be passed on to later records. As a result, error occurrence is eliminated.

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 configuration in which predetermined test data is displayed in advance in a row between data strings, so that the card reader / writer makes a test data string each time it is accessed. First, the access position and angle are adjusted by the test data string, the recorded data string consisting of adjacent display marks is read, and the test data string is first detected when recording data. Positional errors and angular errors caused by writing by different card reader / writers are not accumulated for each access and are not inherited in later recording. As a result, it is possible to eliminate the occurrence of an access error and realize a highly reliable prepaid card and its system, which has a great industrial effect.
