The back clip of the mobile phone protective cover has a card nest that can hold an IC card, usually non-contact proximity cards such as bus IC cards, subway IC cards, access control IC cards, time attendance IC cards, etc. (if there is no contact between the card and the mobile phone) If an anti-magnetic sticker is placed in between, the electromagnetic signal of the IC card will be interfered by the eddy current attenuation of the mobile phone battery, and the IC card and the mobile phone will not be able to sense the card reader, or the sensing will be insensitive, and the misreading rate has been much higher. ); (When an anti-magnetic sticker is placed between the IC card and the mobile phone, the effect is significantly improved. The anti-magnetic sticker can suppress the eddy current interference of the metal back cover of the mobile phone or the metal conductor such as the battery, and it can also enhance the communication field of the IC card. Make it have a strong signal energy to stimulate out the induction card reader, the induction distance becomes farther, and the sensitivity is improved).
The iPhone mobile phone uses a metal casing, and metal has a great interference function on the signal of the IC card. The anti-magnetic sticker is made of ferrite with high magnetic permeability as the raw material, which has super anti-metal interference ability.
The size of the antimagnetic sticker is 0.15mm*85mm*54mm, the size of the standard IC card. It can be used in combination with the IC card or combined with the IC card. When using it, place the antimagnetic sticker on the side close to the Iphone to isolate the IC card from Between mobile phones.
The ferrite sheet with the strongest anti-interference ability so far is born! Experience a product with better mobile phone effect! The anti-interference ability is more than 2 times of the ordinary gray magnetic sticker (Silicon aluminum powder coating)! (The same coil, the same chip, the reading card, the induction distance is more than 1CM than the ordinary antimagnetic sticker) The ultra-high magnetic permeability allows you to use worry-free ! complete in one step! Physical factories provide cost-effective products. Many mobile phones contain metal components. The coils and chips placed around the back cover of the mobile phone must be affixed to the surface of conductive objects such as metal or to places with metal devices nearby. In this way, the alternating electromagnetic field induced by the chip under the action of the signal from the card reader is easily attenuated by the eddy current of the metal, which greatly weakens the signal strength, leading to the failure of the reading process. Therefore, in order to better read the chip, it is necessary to add anti-magnetic stickers in the product.
