Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a prepaid card, and more particularly, to a prepaid card having a forgery prevention function.

[Prior Art] Conventionally, as a method of preventing forgery of a magnetic card, there has been a method of making a hole in the card by punching, or a method of marking or displaying as a character with thermal ink.

[Problem to be Solved by the Invention] The punch type has drawbacks such as generation of punching waste, a large punching unit, and a need for a photosensor or a punch hole detection head.

On the other hand, the heat-sensitive type had drawbacks such as difficulty in confirming the remaining number except by visual observation and instability against chemicals, ultraviolet rays, temperature, and the like.

In order to eliminate these drawbacks, the present invention electrically destroys the pattern of the deposited film, so that no dust is generated by punching scum. The present invention is to provide a prepaid card with high security, by preventing the forgery of the card by matching this data with other recorded data, for example, magnetic data.

[Means for Solving the Problems] According to the present invention, there are provided a plurality of patterns provided with a plurality of conductive vapor-deposited films for determining the remaining number of cards used formed on the surface of the card or the printed surface, Each of the patterns includes a pair of contact portions for conducting electricity, and a destruction portion that extends between the contact portions and is destroyed when electricity is applied between the pair of contact portions, and has a forgery prevention effect. A prepaid card characterized by the following is obtained.

In the present invention, the surface of the prepaid card, for example,
A pattern for the number of uses is created on the magnetic recording layer surface or the printed surface with a conductive vapor-deposited film of Al, Sn, Cu, etc., and a current is applied to the pattern each time the card is used to destroy it.

When checking the remaining number, it is configured to check the continuity of each pattern and read it according to how many patterns are conductive. It can not be reused because it is a destructive type. The remaining number is checked with magnetic data and the number of patterns The security is high.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the embodiment of the present invention, a magnetic card having a remaining number confirmation function will be described as an example of a prepaid card.

FIG. 1 is a plan view schematically showing a magnetic card according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a vapor deposition pattern shown in FIGS. FIG. In FIG. 1, conductor patterns 11, 12, 13, 14, 15, 16,... Formed by a pair of circular portions and a line portion connecting the pair of circular portions on the magnetic recording layer surface 4 of the rectangular substrate 1 have substantially parallel line portions. Are provided in a row.

Note that this pattern can be formed on the printing surface 5.

A conductive material such as Al, Sn, or Cu is used as a deposit for the pattern, and a pattern is formed by providing a mask.

In FIG. 2, the substrate comprises a magnetic recording layer 3 formed on a plastic support 2, and conductor patterns 11, 12, 13, 14, 15 are formed on the surface of the magnetic layer 3 by vapor deposition or the like. In FIG. 3, the pattern is a substantially circular contact portion 11a,
11b and a destruction part 11c connecting them.

It is desirable that the cross-sectional area of the destruction part 11c be 1/10 or less of the cross-sectional area of the contact part, and the thickness of the deposited film constituting this destruction part be 1 μm or less and 2 mm or less in width.

FIG. 4 is a block diagram showing a configuration example of a magnetic card recording / reproducing apparatus shown in FIG.

In FIG. 4, a recording / reproducing circuit 21 for recording / reproducing information on / from a magnetic recording layer of a magnetic card, a card position sensing circuit 22 for detecting a magnetic card position, and a magnetic card transport motor for transporting a magnetic card are provided. It has a motor control circuit 23 for controlling, a short circuit 24 for pattern destruction for destroying the destroyed part of the magnetic card, and a continuity inspection circuit 25 for confirming whether the contact of the destroyed part of the magnetic card is broken. It is controlled by the control circuit 26.

Short circuit 24 for pattern destruction and continuity inspection circuit
Terminals 27 and 28, which contact the contacts of the 25 magnetic cards,
It is shared.

In the magnetic card, the conductive terminals 26 and 27 (not shown) are brought into contact with the two contact portions 11a and 11b, and a current is caused to flow, so that the destructed portion 11c of the conductive pattern is destroyed and the conduction between the two contacts is eliminated.

This operation is performed in synchronization with the use circuit of the card, and the number of times of use is marked.

When reading information recorded on the magnetic recording layer, the number of conductive contacts is checked, and it is compared with the magnetic information to determine whether the card is a legitimate card. As a result, it is possible to discriminate a forged card using no card having a contact point, a falsified card in which a magnetic signal is copied and reused, and a legitimate card.

Further, the magnetic card according to the embodiment of the present invention can be applied to a ticket, a coupon, a fuse for a weak current, and the like, in addition to preventing forgery of the magnetic card.

[Effects of the Invention] As described above, according to the present invention, the pattern of the deposited film is electrically destroyed, so that no dust is generated from the punched residue. Usage data can be obtained, and this data is non-rewritable and non-reusable, so that counterfeit cards can be easily found and card counterfeiting can be prevented. ， Prepaid cards with high security can be provided.
