Abstract

(57) [Summary] [Purpose] To provide a prepaid card that can record many transactions in a small printing space. [Structure] On the card surface, a semicircle filled circle mark 2 is on either side of "0" or "1" of each bit of the balance data composed of binary numbers, and the other side is the color of the card surface. At the position where the balance is displayed on the prepaid card 1 where the balance is displayed by, either the "0" or "1" side of each bit of the other balance data composed of binary values is completely filled with a circle mark. 3 is overwritten, and the full circle mark 3 is overwritten to cover the semicircle circle mark 2.

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 balance data is displayed on the surface of the card as a combination of marks so that the card can be overwritten.

[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.

Therefore, mainly for the purpose of preventing data tampering and fraud, a prepaid structure in which the balance is printed and displayed as a binary data mark on the surface of a paper or plastic card and the display is updated each time the balance is updated. Cards are being used. In such prepaid cards, the balance display consisting of a series of marks is added and printed side by side with the old balance display at each transaction.

[0004]

[Problems to be solved by the device]

 With the conventional prepaid card as described above, the printing space for the balance display is limited, so if many transactions are made, the space will fill up in a short period of time and subsequent writing and recording will not be possible. There was a flaw. As a result, users who are full of space need to take the troublesome procedure of reissuing a new prepaid card with their current balance.

The present invention has been made to solve the problems of the prior art, and its object is to provide a prepaid card capable of recording many transactions in a limited small print space. is there.

[0006]

[Means for Solving the Problems]

 The prepaid card of the present invention has a semicircle filled circle mark on either side of "0" or "1" of each bit of the balance data composed of binary numbers on the surface of the card and the other side. In the prepaid card in which the balance is displayed by the color of the card surface, at the position where the balance is displayed, one of the bits "0" and "1" of each bit of the other balance data composed of binary values is displayed. The full-filled circle mark is overwritten, and the full-filled circle mark is overwritten over the semi-circle filled circle mark. Alternatively, at least one of the indicators constituting each of the balances on the surface of the card is a mark.

[0007]

[Action]

 The prepaid card of the present invention configured as described above is printed with a semicircle filled circle mark and is overwritten with the full circle mark to cover the semicircle filled circle mark. When the filled circle mark corresponds to "1", it is "1" if all filled circle marks are printed after overwriting, and other semi-circle filled circle marks or blanks (card surface) are displayed. If so, it can be determined as "0". Therefore, it is possible to write twice in a small print space, and it is possible to handle more transaction records.

【Example】

 FIG. 1 is a plan view of an embodiment of the prepaid card of the present invention. FIG. 2 is an explanatory diagram of overwriting printing of the prepaid card of the present invention. FIG. 3 is a logical table for overwriting printing of the prepaid card of the present invention. Hereinafter, an embodiment of the present invention will be described with reference to FIGS. The prepaid card 1 of the present invention sequentially displays the residual amount for each transaction on each row L1 to L4 of the matrix on the card surface 1A. In FIG. 1, a balance display in which a plurality of semicircle filled circle marks 2 are printed at corresponding positions of columns C1 to C7 is sequentially printed from rows L1 to L4, and data already transacted in row L4 is also displayed. It is printed. That is, the semicircle filled circle mark 2 is printed on L4 and C1, L4 and C2, L4 and C4, L4 and C6, respectively.

Therefore, the printing space of the prepaid card 1 is filled up. Here, the present invention returns to the row L1 again, and performs overwriting printing by the combination of the all-filled circle mark 3 and the blank. As shown in the logic table in Fig. 3, if the first printed display on the card surface is a semi-circle filled circle mark, the first print will be made if the full filled circle mark is overwritten as the second print. The semicircle filled circle marks in the display are not covered, so only the full circle marks are displayed. The same applies when the first printed display is blank.

If the first print display that has already been made on the card surface is a semicircle filled circle mark, and if the overwriting as the second print is blank, only the semicircle filled circle mark is displayed. The reading device can distinguish between the semi-circle filled circle mark and the full-filled circle mark by the difference in light quantity or the pattern recognition, and therefore, this is regarded as blank in the overwriting as the second printing. The same applies when the first printout is blank. As described above, overwriting is possible. Further, especially when the reading is performed by pattern recognition by contour extraction, the semicircle filled circle mark exists on the boundary between the filled semicircle 2C and the unfilled semicircle 2A as shown in FIG. Since the line 2B that intersects the center appears, the shape difference from the circle can be easily understood, and thus accurate pattern recognition is possible.

Returning to FIG. 1, all the filled circle marks are printed in C1 and C2 in the row L1, and the old semicircle filled circle marks are displayed in C3 to C7. Thus, for example, if the all-filled circle mark is defined as "1", the balance will be 1100000. Similarly, the balance of row L2 is 1001000, and since there is no full circle mark below this, it can be seen that the latest balance is displayed.

[0012] It is desirable that all the filled circle marks and the half circle filled circle marks be formed in black. In addition, at least one of the balance data printed on the card surface must be a semicircle filled circle mark in the first recording, and must be a full circle mark in the second recording.

[0013]

[Effect of device]

 As described above, the prepaid card of the present invention has already been printed with the combination of the semi-circle filled circle mark and the blank, and then the full-filled card overlaid with the semi-circle filled circle mark is overwritten. Since it is composed of circle marks, for example, when all the filled circle marks correspond to "1", it is "1" if the all filled circle marks are printed after overwriting. If a semicircle filled circle mark or blank (card surface) appears, it can be judged as "0". Therefore, it is possible to write twice in a small print space, and it is possible to realize a prepaid card that can record more transactions, which is very effective in the industry.
