Description

  The present invention accommodates a magnetic tape carrier, such as a cash card, a credit card, a savings passbook, etc. with a magnetic tape on which various information such as card information and savings information is magnetically stored, and makes it difficult to read magnetic information from the outside. The present invention relates to a container for a magnetic tape carrier that has been made impossible or impossible.

  In recent years, for example, card information stored on a magnetic tape affixed to a credit card or cash card is read by a magnetic reader called a skimmer, and the card information is written on a magnetic tape affixed to a card of the same standard. There are frequent skimming crimes in which a counterfeit card is manufactured and the counterfeit card is used to illegally acquire cash and other goods.

The magnetic reading device can read the card information on the magnetic tape in a non-contact manner with respect to the card. In recent years, the card information on the magnetic tape can be read even from a position several tens of centimeters away from the card. High performance and downsizing.
For this reason, even if the card is still in the wallet or the like, the card information on the magnetic tape can be read just by bringing the magnetic reader close to the wallet or the like. The fact is that the number of matching cases is increasing.

  The above-mentioned drawbacks can be solved by integrating an IC chip in which various card information is electrically stored in the card and making it impossible to read the various card information by the magnetic reading device described above. In this case, for example, an existing ATM or the like for a magnetic card cannot use an IC card, and there is a problem that the use of the card is restricted and inconvenient. In addition, when changing to an ATM that can be read by an IC card, there is a problem that the exchange is expensive.

  In addition, as shown in Patent Document 1, a highly permeable plate such as permalloy that shields magnetism is attached to a wallet or card holder in which various cards are accommodated, so that the card information stored on the magnetic tape cannot be read from the outside. What has been proposed. However, since the highly permeable plate itself is a highly rigid and heavy metal plate, the wallet for storing the card itself is heavy and difficult to bend, so it is inconvenient to carry and difficult to use. Yes.

In addition, when there is a device that generates strong electromagnetic waves or magnetic fields such as a mobile phone, an electric motor, or a magnet near the wallet that contains the card, the magnetic information stored on the magnetic tape of the stored card is externally stored. There is a problem that it cannot be used because it is destroyed by electromagnetic waves and magnetic fields from

  The problem to be solved is that the magnetic information of the accommodated magnetic tape carrier can be easily read from the outside. In addition, the magnetic information of the accommodated magnetic tape carrier is destroyed by external electromagnetic waves or magnetic fields and becomes unusable. Furthermore, it is difficult to bend easily during use and is difficult to use. Furthermore, it is inconvenient to carry in weight.

  In the present invention, a magnetic shield containing a high magnetic permeability material powder is affixed to at least a magnetic tape carrier on the inner surface of a container that accommodates a magnetic tape carrier to which a magnetic tape storing various information is affixed. It is provided so as to cover both sides of the magnetic tape.

  The present invention can make it difficult to read the magnetic information of the accommodated magnetic tape carrier from the outside. Further, it is possible to prevent the magnetic information of the accommodated magnetic tape carrier from being destroyed by an external electromagnetic wave or magnetic field. Furthermore, it can be easily folded at the time of use while ensuring weight reduction, and is convenient to carry.

According to the present invention, the best mode is that a magnetic shielding body containing highly magnetic material powder is provided on the inner surface of the container so as to be attached to at least the magnetic tape carrier so as to cover both surfaces of the magnetic tape.

The present invention will be described below with reference to the drawings showing embodiments.
1 and 2, the wallet 1 constituting the magnetic tape carrier holder is in the shape of a long folded bill, and a card slot 1a and a plurality of card holders 1b as magnetic tape holders are provided inside. It has been. The wallet 1 may be made of leather, cloth, soft synthetic resin cloth, or the like. And each card accommodating part 1b is comprised so that the cards 3, such as a credit card and a cash card as a magnetic tape carrier with which the magnetic tape 3a by which various card information was magnetically memorize | stored on the back surface, for example were stuck may be accommodated. Is done.

  A magnetic shielding plate 5 is internally provided on the inner surface of both exterior members 1c of the folded wallet 1. The magnetic shielding plate 5 is large enough to cover the entire inner surface of both the outer packaging materials 1c of the wallet 1, and has a thin hinge portion so that it can be bent at an intermediate portion, and can be bent. As the magnetic shielding plate 5, high permeability material powder such as Ni-Fe alloy powder or amorphous alloy powder is contained in a ratio of about 50 to 90 wt% in rubber material or flexible synthetic resin. It is formed into a sheet having a desired thickness. The above-mentioned Ni-Fe alloy is called a permalloy alloy, and when the Ni content is large, it is difficult to pulverize, so the content is preferably about 30 to 50%.

The content of the highly permeable material powder in the magnetic shielding plate 5 is appropriately set based on the relationship between the bending durability of the magnetic shielding plate 5 itself, the required thickness, and the degree of magnetic shielding. For example, the magnetic shielding plate 5 When the thickness itself may be sufficient, the content may be reduced. On the other hand, when the thickness is thin, the content of the high magnetic permeability material powder may be increased. The magnetic shielding plate 5 is covered with a lining material 7 attached to the back surfaces of the two exterior materials 1c, so that it is not exposed when the wallet 1 is spread.

  The magnetic shielding plate 5 attached to the wallet 1 functions as follows, and prevents magnetic data of the magnetic tape 3 a attached to the card 3 from being read from the outside by the magnetic reading device 9.

  That is, the magnetic tape 3a of the card 3 accommodated in the card accommodating portion 1b of the wallet 1 forms a weak magnetic field corresponding to the stored magnetic information. When this magnetic field acts on the highly permeable material powder contained in the magnetic shielding plate 5, the magnetic field penetrates into the highly permeable material powder contained in the magnetic shielding plate 5 to form a magnetic circuit. To prevent the magnetic field from leaking outside. For this reason, even when a magnetic reader (not shown) is brought close to the wallet 1 in which the card 3 is accommodated, it is possible to prevent magnetic information from being read by the magnetic field generated from the magnetic tape 3a by the magnetic reader. it can.

  When there is a magnetic field generating device (not shown) such as a mobile phone, an electric motor, or a magnet near the wallet 1 containing the card 3, the electromagnetic wave output from the mobile phone that is the magnetic field generating device or driving of the electric motor There is a possibility that the magnetic information written on the magnetic tape 3a is destroyed by the magnetic field generated along with the card 3 and the card 3 becomes unusable.

In the wallet 1 of the present embodiment, when there are devices or members that generate electromagnetic waves or magnetic fields such as mobile phones, electric motors, magnets, etc. nearby, the high permeability contained in the magnetic shielding plate 5 The magnetic powder from the magnetic field generating device is permeated by the material powder to form a magnetic circuit, and by absorbing the magnetic loss, external electromagnetic waves and magnetic fields act on the magnetic tape 3a to destroy the magnetic information. It is possible to prevent the card 3 from becoming unusable.

The present invention can be modified as follows.
1. In the above description, the magnetic tape carrier is explained using a card such as a cash card or a credit card, but a magnetic tape on which passbook information is magnetically stored is pasted, for example, a bankbook passbook or personal information is magnetic. It may be an ID card or the like on which a magnetic tape stored in is attached.

2. In the above description, the magnetic tape carrier container is described as the wallet 1, but it may be a card holder that accommodates only a card, a passbook holder, a bag, a bag, or the like.

3. Although the said description set it as the structure which provides the magnetic shielding board 5 in the whole inner surface of the exterior | packing material 1c in the wallet 1 as a container for magnetic tape carriers, the magnetic shielding board 5 was affixed on the accommodated card 3. What is necessary is just the structure provided so that both surfaces of the magnetic tape 3a may be covered.

4). In the above description, the magnetic shielding plate 5 has a configuration in which a rubber material or a synthetic resin having flexibility contains a highly permeable material powder such as Ni-Fe alloy powder or amorphous alloy powder. However, it may be a paper body or a fiber body such as a fiber containing a highly magnetic material powder such as Ni-Fe alloy powder or amorphous alloy powder.

In the case of using a fibrous body as paper, the highly permeable material powder is directly contained when the paper is produced, or the highly permeable material powder is adhered to the front and back surfaces of the produced paper at a desired thickness. The magnetic shielding layer may be formed. In the case where the fibrous body is a woven fabric or a non-woven fabric, the structure in which the highly permeable material powder is physically contained in or adhered to the manufactured fiber, or the highly permeable material is added to the fiber material. It is good also as the fiber manufactured containing fine powder.

It is a partially broken perspective view which shows the wallet which actualized the container for magnetic tape carriers. It is a longitudinal cross-sectional view of a wallet.
