What is the role of RFID/NFC magnetic separator?

Author:admin   AddTime:2021-07-13

In recent years, various new applications based on NFC/RFID technology have ushered in an unprecedented period of rapid growth, especially the extremely popular mobile payment market. In 2014 alone, the transaction value reached nearly 325 billion U.S. dollars. Compared with the transaction value of 235.4 billion US dollars, an increase of 38%, and in the foreseeable future, the global mobile payment market will continue to maintain a compound growth rate of about 40%. RFID/NFC magnetic spacers are also emerging!
 
The potential of the RFID/NFC magnetic separator market is undoubtedly huge. However, because of the technology-driven technology industry of NFC/RFID, it has to be said that today’s NFC/RFID still has many technical obstacles that are difficult to overcome. This is also an important reason that hinders the further expansion of the market.



At present, one material used to solve the interference problem is RFID/NFC magnetic isolation sheet. Generally speaking, RFID/NFC magnetic isolation sheet is a soft magnetic material (Hc<100A/m), and NFC/RFID design uses RFID/NFC magnetic isolation sheet, which is also a wave-absorbing material.

What is the specific function of the so-called RFID/NFC magnetic barrier? When NFC/RFID is working, the magnetic field formed by the antenna is susceptible to interference from metal and other objects, resulting in unnecessary errors in device identification. The use of RFID/NFC magnetic isolation sheets can eliminate this error, for example The NFC/RFID antenna is generally placed between the back cover of the mobile phone and the battery, and the battery is likely to cause interference to the magnetic field. At this time, we only need to put a layer of absorbing material between the antenna and the battery to eliminate this interference. The adverse effects. Moreover, RFID/NFC magnetic barriers also have a large number of applications in wireless charging and EMI.

These materials can well solve the interference problems of RFID/NFC/wireless charging and other applications! Promote the continuous and rapid development of the Internet of Things!
