The former can be used for bus or access control, and the latter can get rid of the shackles of cables.
It is mainly used as the initial verification of Bluetooth and wireless connections.
Key coil The NFC module on a smartphone usually includes a complete CLF (contactless front-end module), radio frequency antenna, and SE (safe area) units, and the most impressive thing is undoubtedly a striking coil.
Its working principle is based on the mutual coupling of inductances, which regularly changes the impedance of the coil to regularly change the load of the primary coil of the inductance, so as to allow the coil in the reader end (which can be a mobile phone or a bus gate, etc.)
Yes, the wireless charging technology commonly used in mobile phone loops at this stage is based on electromagnetic induction.
Its principle is the Faraday battery induction law, which is to give the primary coil a certain frequency of alternating current and generate a certain current in the secondary coil through electromagnetic induction.
