Product Description:

RFID copper coils are a key component of the antenna section in RFID systems,  typically made of high-purity copper wires (enameled or silver-plated) through a precision winding process. Its core function is to complete electromagnetic coupling: on the tag side, it is responsible for capturing energy from the reader's electromagnetic field, activating the chip and transmitting data back; On the reader side, it is responsible for establishing and maintaining a stable electromagnetic field. Its performance directly determines the read/write distance, sensitivity, and stability of the entire RFID system.

Parameter：

Application:

1. High-performance labels and cards:Financial payment and security authentication: bank cards, e-passports, high- end access control cards. The most stable read and write performance and the highest security are required.

2. Industrial asset management label: used to track tools, equipment, gas cylinders, etc., often encapsulated in a rugged shell, which needs to work stably in harsh environments.

3. Special labels: anti-metal labels, implantable biological labels (glass tube labels), jewelry management labels, etc., with extremely small space and harsh environment.

4. Miniaturization and implantable devices: Micro NFC tags (integrated inside mobile phones, wearable devices), medical implantable devices (such as RFID-tagged surgical gauze, animal chips), etc., have extreme requirements for coil size and efficiency.

5. Reader and professional equipment antenna: As a handheld, fixed reader, the near-field coupled antenna needs to generate a stable and uniform magnetic field, which requires extremely high accuracy and consistency of the coil.

6. High-end consumer electronics: The NFC payment antenna and wireless charging receiving coil inside the smartphone all use high-performance copper coils for the best user experience.
