Background
Plastic cards with embedded microchips are called smart cards, which are typically the size of a credit card. Smart cards include magnetic stripe cards and chip cards. Magnetic stripe cards are card-like magnetic recording media that use a magnetic carrier to record characters and digital information for identification or other purposes. The magnetic strip card is made of high-strength and high-temperature-resistant plastic or paper-coated plastic, can prevent moisture and wear, has certain flexibility, is convenient to carry, and is relatively stable and reliable to use. For example, the bank card we use is one of the most common magnetic stripe cards.
However, in the smart card only, the magnetic strip is located on the surface of the smart card, and when the surface of the magnetic strip is acted by external force, the magnetic strip is easily demagnetized to cause abrasion of the magnetic strip.

In order to achieve the purpose, the utility model adopts the following technical scheme:
the utility model provides a prevent smart card of magnetic stripe wearing and tearing, includes the card body, electromagnetic shield protective case and inlays to be located the positive magnetic stripe of the card body, the back of electromagnetic shield protective case is equipped with first sand grip and second sand grip, the card body openly is offered and is used for holding the first recess and the second recess of first sand grip and second sand grip, the magnetic stripe is located between first recess and the second recess, be equipped with first magnetism connecting piece on the face-to-face of first sand grip and first recess respectively, be equipped with second magnetism connecting piece on the face-to-face of second sand grip and second recess respectively, one side of electromagnetic shield protective case is equipped with the fixture block.
Further, the electromagnetic shielding protective shell is made of an electromagnetic shielding material.
Furthermore, the fixture block is close to the front face of the electromagnetic shielding protective shell.
Further, first magnetic connecting piece includes just to first electromagnet and the second electromagnet that sets up, first electromagnet inlays to be located the tank bottom of first recess, the second electromagnet is located on the first sand grip.
Further, the second magnetic connecting piece comprises a third electromagnet and a fourth electromagnet which are opposite to each other, the third electromagnet is embedded in the groove bottom of the second groove, and the fourth electromagnet is arranged on the second convex strip.
The utility model has the beneficial effects that:
in practical application, when the electromagnetic shielding card is used, the clamping block is pulled, the electromagnetic shielding protective shell is taken down from the card body, the magnetic stripe can be exposed, and then the card body with the exposed magnetic stripe is normally used for swiping a card; after the card swiping is finished, aligning the first raised line with the first groove, aligning the second raised line with the second groove, and adsorbing the electromagnetic shielding protective shell on the card body through the first magnetic connecting piece and the second magnetic connecting piece; the magnetic stripe demagnetization caused by an external magnetic field can be effectively prevented through the electromagnetic shielding protective shell; the utility model can effectively prevent the magnetic strip from being demagnetized or worn, and prolong the service life of the magnetic strip.
