Application of RFID/NFC absorber materials

In RFID/NFC absorber devices, the electronic tag needs to be integrated or catered to the device to fully function as a component of the device. Usually, the space is limited, and it is difficult to avoid attaching the electronic tag (usually active) to the conductive metal such as metal. The surface of the object or the place where there are metal components in the vicinity. In this way, under the action of the data signal transmitted from the SD card reader, the logo excites the alternating magnetic field induced by the magnetic induction, which is very susceptible to the eddy loss effect of the metal, which greatly weakens the network signal, causing the loading process to be ineffective. success. Therefore, it is necessary to improve the anti-metal material absorbing material in the product to improve the sensitivity of the card reader.

Characteristics of NFC absorber materials:

The absorbing material is a functional composite material that absorbs electromagnetic waves as the main function. It removes the round-trip reflection surface that shields the electromagnetic waves in the cavity, reduces the impact of noise on its own equipment, and reasonably avoids the interference and damage of electromagnetic wave radiation to peripheral equipment and employees. It is an advanced way to remove electromagnetic wave pollution.

The use of NFC absorber materials in electronic devices can absorb leaked electromagnetic wave radiation and achieve the purpose of eliminating electromagnetic interference. According to the regularity of electromagnetic waves spreading from low magnetic guiding and high magnetic permeability azimuths in materials, high magnetic permeability ferrite is used to correctly guide electromagnetic waves. Through resonance, many radiation sources of electromagnetic waves absorb the kinetic energy of electromagnetic waves. converted into heat.

The operation process of NFC absorber magnetic sheet

1. Replacing existing cards with NFC tags is user-friendly and easy to carry. The NFC tag is attached to the customer’s mobile phone to complete the functions that can be achieved by a contactless card. It can realize the functions of large-scale terminal customer identification, consumption points, and customer special services.
2. In commercial promotion, the specific information of the promotion is written on a poster with an NFC absorber tag, and the customer uses a mobile phone with an NFC card reader, closes the tag, and instantly completes a series of set functions.
3. In mobile payment, stored value consumption, point consumption and other systems, NFC absorber tags can realize high-security commercial consumption and payment transactions with user password security authentication.
4. Mutual data connection and data transmission of NFC absorber devices, such as data file transmission, identification, exchange, data synchronization processing, data between devices, various functional operations between devices and the background.
