Description

Electronic record carrier with electromagnetic barrier function

The present invention relates to an electronic record carrier protective cover having an electromagnetic barrier function, in particular to a soft magnetic sheet which is specially provided inside the protective cover, at least one layer which is soft and not easily folded and broken, so as to be adapted to softly accommodate an electronic record carrier. The requirements of the object, and also provide the protection of the contents of the protective cover from external magnetic fields (forces), or suffer from the recording of the pirate device.

On top of most commercial card vouchers and common bank passbooks, there is a magnetic stripe or chip for recording customer or member data for the user to access the transaction data and to access and identify the data of the automation device; Card vouchers and passbooks are not in use, and are mostly stored in a protective cover to avoid being scratched, damp or stained by foreign objects.

However, the protective cover that is commonly seen at present, for another passbook outside the set or the magnetic strip on the card voucher is approached or contacted by other magnetic objects or electronic skimming devices, and does not provide effective protection; for this reason, In the partial protective cover structure, a magnetic anti-blocking card formed of a metal layer is disposed at a position where the surface of the cover body is placed relative to the magnetic strip, but the type of the magnetic anti-blocking card is too hard and easy. The effect of losing the electromagnetic barrier and reducing it has not been widely promoted to related products.

In view of the fact that the traditional protective cover disclosed above can not offset or block the penetration of the external magnetic field (force) or electronic side recording signal, or is easily damaged by external force and lose the barrier magnetic field (force), the creator of this case specially designed and provided A protective cover capable of effectively blocking the external magnetic field (force) interference of the protective cover or stealing data by the skimming device, for the passbook or card placed in the protective cover, and having the softness which is not easily broken or damaged by external force Toughness to improve the lack of traditional people.

Therefore, the present invention mainly consists of forming a casing having a receiving space by sealing the two skin layers at a partial edge, and at least a soft magnetic sheet capable of generating a magnetic barrier is formed in the receiving space between the two skin layers. The soft magnetic sheet is a sheet made of a flexible magnetic material (for example, rubber) mixed with a magnetic conductive material, which has flexibility and is not easily broken, and has a uniformly distributed magnetic conductive material, and can provide a suit to accommodate the passbook or card. The softening effect of the deformation and opening sleeve required for the process is more difficult to be damaged by external force bending, and the diamagnetic or magnetic resistance effect can be effectively maintained without loss.

Another purpose of the creation is on the above soft magnetic sheet, and then a layer of metal foil is laminated, so that the electronic side recording electric wave outside the sleeve can be rebounded by the metal foil and cannot penetrate the metal foil to further prevent the side recording. The role.

The structure, means and effectiveness of this creation are further explained in conjunction with the above diagram:

Referring to FIG. 1 , the present invention is formed by sealing the two surface layers 10 and 11 with their corresponding partial edges 101 and 111, and forming a casing 1 having a receiving space 12 between the two surface layers 10 and 11 and In the accommodating space 12 between the two skin layers 10, 11, at least one soft magnetic sheet 2 (two layers are shown) is provided; the soft magnetic sheet 2 is made of a soft and plastic material (such as plastic or rubber). 21, after mixing at least one magnetic conductive material (for example, powder of metal such as aluminum, silver, iron, copper, etc.) 22; the prepared sheet has the characteristics of being soft and adaptable to a large tortuosity, and the magnetic magnetic material contained therein 22 has good magnetic field (force) guiding and blocking ability, and therefore, is disposed in the inner accommodating space 12 of the two surface layers 10, 11, and can be fully adapted to the housing 1 for accommodating or taking cards or passbooks. The process of 4th electronic record carrier, the soft deformation and closing function required, and it is not easy to be broken or broken due to the opening and closing deformation, and the soft characteristic can be unexpected to external force. The collision produces a cushioning effect, giving the built-in card and passbook a protection effect superior to the traditional single-layer glue or cloth surface layer; further, the soft magnetic sheet 2 contains a uniform magnetic conductive material 22, Further, when the outside of the casing 1 is subjected to a magnetic body or a magnetic field (force), the magnetic field (force) is provided with a barrier or absorption of magnetic conduction, and the magnetic field (force) is prevented from penetrating to cause magnetic force on the card or the passbook 4. The strip 41 is demagnetized by the magnetic field (force) to achieve anti-demagnetization.

In an embodiment, the flexible magnetic sheet 2 may be layered with the two skin layers 10 and 11, and the soft magnetic sheet 2 may be attached to the inner surfaces of the two skin layers 10, 11 or the two soft magnetic layers of the inner surface. The sheet 2 and the accommodating space 12 may be separated by at least one inner surface layer to provide a superior protection for the content card or the passbook 4; and the outer surfaces of the two surface layers 10 and 11 may be printed with a beautiful pattern or display as needed. Layer, combined with Chen Ming.

As shown in Fig. 4, on the soft sheet 2 of the present invention, a metal foil 3 (for example, aluminum foil) can be further laminated, so that the electronic side recording device (not shown) of the outside of the casing 1 can be further The side-recording electric wave generates a reflection blocking function to provide the electronic body of the casing 1 further having an anti-theft card or a magnetic strip.

In summary, the protective cover of the present invention, in addition to the excellent anti-fouling or moisture-proof effect on the card or passbook, further provides a barrier magnetic field (force) effect that is determined and not easily broken, and can provide a card or passbook. The magnetic stripe on the anti-degrosion function can effectively improve the traditional same type of protective cover. On the whole, it is indeed an excellent industry that has the advantage of using patents in accordance with the law.
