When the communication distance is shortened due to proximity to metal and it does not operate, it is used on the NFC reader side such as smartphones, digital health devices, home appliances, and in-vehicle devices.
● The NFC/RFID system, which is a global standard, is being adopted in transportation-related contactless IC cards and electronic money, expanding convenience. ● From card form factors to system-compatible mobile phones and smart devices, small mobile electronic devices are equipped with reader/writer (R/W) functions, enabling the active use of inexpensive NFC tags. ● As a result, everything and everywhere can connect to internet services, allowing even white goods and healthcare devices without network connectivity to connect to the internet through smartphones and start collaborating with various cloud services. ● The biggest advantage is that the system can be built without placing a special burden on stores or users. ● On the other hand, when incorporating into small mobile electronic devices, it is inevitably necessary to be close to metals such as printed circuit boards, so a method is employed that has a magnetic shielding effect between the metal surface substrate and the tag antenna, while also placing low-loss soft magnetic materials. ● This allows the incident magnetic flux to pass through the layer of high permeability material and return from the end face, enabling communication even when an RF tag is attached to a metal surface.

basic information
●NFC/RFID Countermeasure Sheet: The proximity wireless communication technology "NFC (near field communication)" will enable mobile devices to have reader/writer (R/W) functionality. ●As a result, inexpensive NFC tags can be actively utilized. Consequently, everything and everywhere will be connected to internet services. ●Even white goods and healthcare devices that do not have network connectivity will start connecting to the internet through smartphones and collaborating with various cloud services. However, when NFC and RFID are incorporated into mobile phones and smartphones, they inevitably come into close proximity with metals such as printed circuit boards, leading to phenomena where the communication distance shortens or the devices fail to operate. ●The MS-T series has achieved high magnetic shielding effectiveness and low loss to address these issues.

Detailed information
-
RFID/NFC Interference Countermeasures - Noise Suppression Sheet The noise suppression sheet has a structure in which flat powder made of soft magnetic material with high permeability is uniformly dispersed in a resin material, and the particles are electrically isolated from each other. By placing the sheet in an electromagnetic interference space, inductive coupling is suppressed. When used on transmission lines, high-frequency noise is attenuated, effectively suppressing unwanted radiation without secondary effects such as secondary radiation or signal degradation.
