JP3012625U - Prepaid card for overwriting - Google Patents

Abstract

(57) [Summary] [Purpose] To provide a prepaid card that can record many transactions in a small printing space. [Structure] On the card surface, each bit of the balance data composed of binary numbers is a cross mark 2 on either side of "0" or "1", and the other side is the balance depending on the color of the card surface. On the displayed prepaid card 1, at the position where the balance is displayed, overwrite either side of "0" or "1" of each bit of the other balance data composed of binary numbers with a filled circle 3. The filled circle 3 is overwritten so as to cover the inclined cross 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 an inclined cross mark on either side of "0" or "1" of each bit of the balance data composed of binary numbers on the card surface and the other side on the card surface. In the prepaid card in which the balance is displayed in the color of, at the position where the balance is displayed, fill either side of "0" or "1" of each bit of the balance data composed of binary values with a filled circle. The mark is overwritten, and the filled circle mark is overwritten so as to cover the inclined cross 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 the slanted cross mark and is overwritten by the filled circle mark covering the slanted cross mark. For example, the filled circle mark becomes "1". In a corresponding case, after the overwriting, it can be judged as "1" if the filled circle mark is printed, and as "0" if any other inclined cross mark or blank (card surface) appears. 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 slanted cross marks 2 are printed at corresponding positions in columns C1 to C7 is printed in order from rows L1 to L4, and the already-transacted data is also printed in row L4. Has been done. That is, the slanted cross 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 filled circle mark 3 and the blank. As shown in the logic table of FIG. 3, when the first printed display made on the card surface is an inclined cross mark, when the filled circle mark is overwritten as the second printing, the first printed display tilts. The cross mark is covered, so only the filled circle mark is displayed. The same applies when the first printout is blank.

If the first printed display made on the card surface is the slanted cross mark and the overwriting as the second print is blank, only the slanted cross mark is displayed. Since the reading device can distinguish the slanted cross mark and the filled circle mark by the difference in the light quantity or the pattern recognition, this is regarded as a blank in the overwriting as the second printing. The same applies when the first print display is blank. Overwriting is possible as described above. Further, when the reading is performed by pattern recognition, the inclined cross mark has a line 2A that crosses the vicinity of the center with an inclination angle of 45 degrees as shown in FIG. This not only makes it easy to see the difference in shape from the circle, but also reduces the effect of noise that occurs when the card progresses, thus enabling accurate pattern recognition.

Returning to FIG. 1, a filled circle mark is printed on C1 and C2 in the row L1, and an old slanted cross mark is displayed from C3 to C7. As a result, if the filled circle mark is defined as "1", the balance becomes 1100000. Similarly, the balance of row L2 is 1001000, and since there is no filled circle mark below this, it can be seen that it is the latest balance display.

It is desirable that the filled circle mark and the slanted cross mark be formed in black. In addition, at least one of the balance data printed on the surface of the card must be an inclined cross mark in the first record and must be a solid circle mark in the second record.

[0013]

[Effect of device]

 As described above, the prepaid card of the present invention is already printed with the combination of the slanted cross mark and the blank, and is provided with the filled circle mark overlaid on the slanted cross mark. Therefore, for example, when the filled circle mark corresponds to "1", it is "1" if the filled circle mark is printed after overwriting, and other inclined cross marks or blanks. If (card surface) is visible, it can be determined 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 has a great industrial effect.
