[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a magnetic card such as a telephone card, and more particularly to a magnetic card having not only magnetic data but also card authenticity determination data and a card reader for reading the data of the magnetic card.

[0002]

[Prior Art]

 Generally, in this type of magnetic card, magnetic data corresponding to a predetermined telephone frequency is written in advance on the magnetic layer of the card, and the magnetic data is rewritten by subtracting the telephone call frequency. Is. In addition to the magnetic data, card authenticity discrimination data for discriminating the authenticity of the card is provided. Usually, this card authenticity discrimination data is written by a method different from magnetic data, and, for example, bar code data is printed on the surface of the card as print data. This bar code data is printed with the initial value data of the card, and the authenticity of the card is determined by the relation between the magnetic data and this bar code data. The card possessed is determined to be an incorrect card in relation to the bar code data.

[0003]

[Problems to be solved by the device]

 By the way, as shown in FIG. 3, the above-mentioned magnetic data and the card authenticity determination data are arranged such that the magnetic track 30a on which the magnetic card is written extends below the card 30 and the card authenticity determination is performed. The structure is such that each bar code 30b, which is data, is printed at a different position on the card so that it is printed on the left side near the upper end. For this reason, the card 30 is cut along the line BB, and the lower end portion 301 on the side having the magnetic track 30a in which the falsified magnetic data is written is cut off from the line CC of the other card 40. When the card 40 is attached instead of the lower end portion 401 on the side having the 40a, a new relation is generated between the card authenticity determination data by the barcode 40b of the card 40 and the magnetic data of the magnetic track 30a, and the card 40 Therefore, there is a problem that fraud may occur.

Therefore, the present invention has been made in view of the above-mentioned conventional inconveniences, and an object of the present invention is to provide a magnetic card and a card reader device which prevent unauthorized use. ..

[0005]

[Means for Solving the Problems]

 In order to achieve this purpose, a magnetic card according to the present invention comprises a magnetic layer provided with a magnetic track on which magnetic data is written, and a card authenticity discrimination data laminated on the surface side of the magnetic layer. And a card identification data layer having a card identification data layer, the card authenticity identification data being arranged at the same position as the magnetic track. Further, the card reader device according to the present invention comprises a magnetic head for reading and writing magnetic data, and a discrimination data reading head for reading card authenticity discrimination data. They are arranged on the same transport line along the direction.

[0006]

[Action]

 In the present invention, if an attempt is made to replace a magnetic track of tampered magnetic data with a magnetic track of another card, the card authenticity determination data will also be exchanged with the magnetic track, or the card authenticity of another card will be replaced. Discrimination data is destroyed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a main part of a magnetic card according to the present invention, and FIG. 2 is a plan view of the card reader. In these figures, the magnetic card 1 has a magnetic layer 3 laminated on a base material 2, a printed layer 4 on the magnetic layer 3, and a protective layer 5 on the printed layer 4. .. On the magnetic layer 3, stripe-shaped magnetic tracks 3a for writing magnetic data are formed so as to extend in the direction in which the magnetic card 1 is conveyed, that is, in the A direction. Initial amount data when the magnetic card 1 is not used, for example, for a 500-yen note, magnetic data for "50 frequencies" is written.

A bar code 4a, which is print data as card authenticity discrimination data, is printed on the print layer 4. The feature of the present invention is that the bar code 4a is the same as the magnetic track 3a. It is located at a position. Similar to the magnetic track 3a described above, the bar code 4a is printed with the data "500 yen" which is the initial amount data when the magnetic card 1 is not used, like the magnetic track 3a. The protective layer 5 is formed of a transparent member, and the bar code 4a is configured to be recognizable and reproducible from the protective layer 5 side by a photo reflector or the like.

The card reader 10 is provided with a card insertion port 12 at the entrance of the card transport path 11, and one side plate 13 of both side plates 13 and 14 for restricting the movement of the card 1 in the width direction is provided with a motor. The rotation of the motor 16 is transmitted to the shaft 20 to which the pulley 18 is fixed by the belt 17 that is attached to the motor pulley 16a and the pulley 18, and the roller 20 and other rollers fixed to the shaft 20. The belt 21 stretched around the roller 22 is driven to take in and discharge the air from the transport path 11 of the magnetic card 1. In the transport path 11, the photo reflector 25 and the magnetic head 26 are arranged on a line 1 separated from the side plate 14 by the same distance T from the side edge of the magnetic card 1 to the magnetic track 3a. It is set up.

In the magnetic card 1 and the card reader 10 configured as described above, when the magnetic card 1 is inserted into the card transport path 11 through the card insertion slot 12, the photo reflector 25 and the magnetic head 26 cause the bar code 4 a to move. Read the print data and the magnetic data of the magnetic track 3a, and compare the relationship between these two data to determine the authenticity of the card. When it is determined that the card is not an illegal card, the magnetic head 26 writes magnetic data according to the call frequency and the card is ejected from the card insertion slot 12 again. At this time, by incorporating the data pattern of the print data 4a into the magnetic data by software processing such as encryption, it is possible to prevent the magnetic data from being forged only by falsification. Further, as the magnetic head 26, one that can generate a magnetic field sufficient to completely magnetize the magnetic layer 3 through the protective layer 5 and the print layer 4 is used.

Here, in order to make an illegal act by the above-mentioned cutting, falsified magnetic data is written in the magnetic track 3a of the card 1 and the portion including the magnetic track 3a is cut out from the card 1 at the same time. Since the bar code 4a is also cut off, even if the bar code 4a is attached to another card, it is determined as an illegal card from both data. Even if the magnetic track 3a is cut off from the bar code 4a, the bar code of another card will be destroyed when cutting only the magnetic track in another card to be attached, resulting in data failure. , It is determined as an illegal card.

In this embodiment, the print data is used as the card authenticity determination data, but the present invention is not limited to this, and various methods can be applied. For example, a hologram method may be used. In this case, It goes without saying that a hologram reading head is used as the discrimination head of the card reader device 10.

[0013]

[Effect of the device]

 As described above, according to the present invention, the card authenticity determination data is arranged at the same position as the magnetic track, so that the card authenticity determination can be performed even when a malicious magnetic card such as cutting is tampered with. Since the data is destroyed or the relationship between the card authenticity discrimination data of the initial legitimate card and the magnetic data is broken, the card is discriminated as a fraudulent card, and thus illegal use of the card can be prevented.
