Abstract

PURPOSE:To prevent forgery of an invalid prepaid card due to regeneration by setting a puncturing position of a punched hole which indicates that the prepaid card is already used up or invalid within the range of a magnetically recording part. CONSTITUTION:A puncturing position for a punched hole 5 which indicates that a prepaid card 1 is already used up or invalid is set within the range of a magnetically recording part 3. For this reason, a punching unit 10 is set side by side with a magnetic head 11, which reads data from a magnetically recording part 2 at a prepaid card 1 reading device. If the prepaid card 1 is used up or invalid, the puncturing position is checked by a punching hole positioning sensor 12 and the punching hole 5 is directly punctured in the magnetically recording part 3 using the punching unit 10. The prepaid card 1 with the magnetically recording part 5 where the punched hole 5 is punctured is no longer able to regenerate correct information, as a discontinuity generates in a magnetic information signal due to the punched hole 5. Thus this incapacitated card is discharged and prevented from being reused after it is interpreted as a source of information error on the reading device side.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for preventing counterfeiting of prepaid cards (prepaid cards).

[Prior Art] In a conventional prepaid card, when the prepaid card is used or invalidated, a part of the punch hole row indicating the remaining balance in the magnetic information indicates that the card is used or invalidated. The punch area shown was set.

Then, it is determined whether the punch is used or invalid depending on whether or not a punch hole indicating that the punch is used or invalid is punched in the punch hole row.

[Problems to be Solved by the Invention] In the above-mentioned conventional system, punch holes indicating used or invalid are provided in the same row as the punch hole row indicating remaining balance information, so it is difficult to attach blind stickers, dead copies, etc. By copying magnetic information, it became possible to reproduce used or invalid cards, allowing counterfeiting.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned conventional problems and to provide a method for preventing counterfeiting of a prepaid card, which can effectively prevent counterfeiting by reproducing a used or invalid prepaid card.

[Means for Solving the Problems] The present invention, which achieves the above object, provides a method for preventing counterfeiting of a prepaid card that includes a magnetic recording section that magnetically records data on a card-like base material. Alternatively, the position of the punch hole indicating invalidity is set within the range of the magnetic recording section.

The second aspect of the invention provides a method for preventing counterfeiting of a prepaid card, which includes a magnetic recording section that magnetically records data on a card-like base material and an information recording section that optically records information. The invention is characterized in that the position of a punch hole indicating that it has been used or is invalid is set in the optical information recording section.

The third aspect of the invention provides a method for preventing counterfeiting of a prepaid card, which includes a magnetic recording section for magnetically recording data on a card-like base material and an information recording section for optically recording information, in which the prepaid card is The device is characterized in that the positions of punch holes indicating that the device is used or invalid are set in both the magnetic recording section and the optical information recording section.

[Examples] Examples of the present invention will be described below with reference to the drawings.

FIG. 1 shows the configuration of a prepaid card counterfeit prevention system according to an embodiment of the present invention.

The prepaid card 1 of this embodiment includes a card-like base material 2 and a strip-shaped magnetic recording section 3, in which data regarding balances and the like is written.

In this prepaid card counterfeiting prevention system, the punching position of the punch hole 5 indicating that the prepaid card l is used or invalid is set within the range of the magnetic recording section 3. For this reason, the reading device for reading the prepaid card l includes a punch unit 10 for punching the punch holes 5 and a magnetic helad 11 for reading data from the magnetic recording section 2.
It is arranged side by side. Further, reference numeral 12 denotes a punch hole positioning sensor for correctly aligning the punching position of the punch hole 5 with the magnetic recording section 3.

When the prepaid card 1 has been used or has become invalid, the punch position is confirmed by a punch hole alignment sensor 12, and the punch hole 5 is punched directly into the magnetic recording section 3 by a punch unit 10. Punch holes 5 in the magnetic recording section 3
In the prepaid card 1 that has been punched, discontinuities occur in the magnetic information signal due to the punched holes 5, making it impossible to reproduce information correctly. In such a card, the reader side determines that there is an information error and ejects the card to prevent its reuse.

Further, even if a blindfold sticker or the like is pasted at the position of the punch hole 5, the magnetic information is destroyed by punching the hole 5 in the magnetic recording section 3 itself, so reproduction of the information by dead copying etc. is impossible. This makes it impossible to forge the prepaid card 1.

FIG. 2 shows another embodiment. In this embodiment, in addition to the magnetic recording section 3, the prepaid card 1 is provided with a barcode type information recording section 7 for optically recording information. The position of the punch hole 5 indicating that the prepaid card 1 is used or invalid is set within the range of the information recording section 7. Further, a new punch unit 15 for punching holes 5 in the information recording section 7 is provided side by side with a reading sensor 16 for reading data from the information recording section 7.

When the prepaid card 1 is used or becomes invalid, the punching position is confirmed by a punching hole alignment sensor 17, and a bunching hole 5 is punched directly into the information recording section 7 by a punching unit 15. In this case as well, the punched holes 5 cause discontinuity in the information signal read from the information recording section 7, making it impossible to reproduce information correctly and preventing reuse. In this case as well, reproduction of information by dead copying or the like becomes impossible, and forgery of the prepaid card 1 becomes impossible.

In the case of the prepaid card 1 having the magnetic recording section 3 and the information recording section 7, the position of the punch hole 5 indicating that the card has been used or is invalid is set to the position of the punch hole 5 of the magnetic recording section 3 and the information recording section 7. It can also be set for both. In this case, a punch unit 1 is used for the magnetic recording section 3 and the information recording section 7.
Needless to say, they each have 0 and 15.

[Effects of the Invention] As explained above, according to the prepaid card counterfeiting prevention method of the present invention, the position of the punch hole indicating that the prepaid card is used or invalid is determined by the magnetic recording section or the optical information. By setting this in the recording section, the information cannot be reproduced by dead copying or the like after the punch hole is punched, so it is possible to prevent counterfeiting of the prepaid card.

In the invention set forth in Item 3, the position of the punch hole indicating that the prepaid card is used or invalid is set in both the magnetic recording section and the optical recording section, making it more difficult to reproduce information and preventing counterfeiting. Furthermore, the effect of reliably preventing this can be obtained.
