NFC payment mainly uses absorbing material technology to reduce or eliminate the interference of RF signals on bank cards or electronic devices

NFC (Non Field Communication Transport) payment is a payment method based on near field communication technology, mainly using AbsorberTechnology is used to reduce or eliminate the interference of radio frequency signals on bank cards or electronic devices.

In NFC payments, absorbing materials refer to materials that can absorb electromagnetic waves and convert them into energy. These materials are generally made of metal or non-metal materials, with a certain thickness and density, and can absorb electromagnetic waves over a wide frequency range and convert them into energy. The main function of these materials is to convert radio frequency signals into energy to support the operation of NFC payment systems.

In NFC payment systems, when bank cards or electronic devices come into contact with NFC materials, induced currents and electromagnetic resonance are generated, which can cause a special interaction between these devices and NFC materials, thereby reducing or eliminating interference from RF signals. This interaction is commonly referred to as "absorption", which can improve the reliability and security of NFC payment systems and help reduce delays in the payment process.

It is worth noting that, Used for NFC payment AbsorberIt is not a single use, but needs to be designed and selected according to specific application requirements. For example, in the field of smart homes, NFC absorbing materials can be used to reduce electromagnetic interference in home systems; In the field of mobile devices, NFC absorbing materials can be used to reduce signal interference in mobile devices; In the field of logistics management, NFC absorbing materials can be used to reduce radio frequency signal interference during logistics processes. Therefore, when choosing absorbing materials for NFC payments, it is necessary to design and select according to specific needs.

NFC payment (Near Field Communication Payment) is also a non-contact payment method that uses close range wireless communication technology to make payments. In NFC payment, the payment device needs to establish a short-range wireless communication connection with the card reader to complete the payment transaction. To ensure the security of the payment process, it is necessary to use absorbing materials to prevent signal leakage and interference.

Absorbing material is a material that can absorb electromagnetic waves. Its main principle is to use the electromagnetic wave absorber in the material to convert electromagnetic waves into thermal energy, thereby achieving the effect of absorbing waves. In NFC payments, absorbing materials are mainly used to prevent signal leakage and interference, ensuring secure and stable communication between payment devices and card readers.

The selection of absorbing materials needs to consider factors such as frequency range, absorbing performance, thickness, and cost. The commonly used absorbing materials currently include various metal materials, carbon fiber materials Graphene materialWait. Among them, graphene material has excellent absorption performance and small thickness, but the cost is relatively high; Metal materials have relatively low costs, but their thickness is large and not suitable for use in small payment devices.

In NFC payment devices, absorbing materials are usually applied inside the shell or antenna of the payment device to prevent signal leakage and interference. At the same time, in order to ensure the overall performance of payment devices, the selection of absorbing materials also needs to consider their impact on the weight, appearance, and manufacturing process of the equipment.
