Hello everyone, I am the editor, do you know ferrite tablets? Today, the editor will analyze it specifically for you, and I hope it will be helpful to you.
In order to make some electronic products better application reading, ferrite absorbing materials are added to the modified products. Below we take the mobile payment application as an example.
The payment method of the payment mobile phone (NFC) is realized through the 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 the greatest 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. In this way, the alternating electromagnetic field induced by the tag under the action of the signal sent by the card reader is easily attenuated by the metal eddy current, which greatly weakens the signal strength, leading to the failure of the reading process.
Therefore, in order for the product to be better used for card reading, it is necessary to add ferrite absorbing materials in the product. The main function 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. By increasing the magnetic field strength, the sensing distance is effectively increased.
