The NFC antenna ferrite sheet is a high-temperature sintered ferrite material.
In handheld devices such as NFC payment mobile phones, the main function of the electronic tag is to reduce the absorption of the signal magnetic field by the metal material. At the same time, the ferrite film itself is a high-temperature sintered ferrite material, which can effectively increase the strength of the magnetic field. Sensing distance.
Mobile payment (NFC) is realized through 13.56MHz RFID radio frequency identification system. The RFID smart label of this application is affixed to the back cover of the mobile phone, which can save space to a certain extent.
In handheld electronic devices such as mobile phones, electronic tags need to be integrated or attached to the electronic device to function as a component of the device. Often due to limited space, it is inevitable to attach RFID tags (usually passive) to metal, etc. The surface of the conductive object or the place where there are metal devices nearby.
The alternating electromagnetic field induced by the tag under the action of the signal from the card reader is easily attenuated by the eddy current of the metal and the signal strength is greatly weakened, leading to the failure of the reading process.
In order for the product to be able to better use the card reader, it is necessary to add a magnetic sheet to the product. The NFC antenna ferrite sheet produced and sold by our company is a material specially developed for the interference encountered during NFC payment.
