Sharing some information about NFC applications I’ve picked up while advancing my current project. First, looking at the underlying standard architecture, NFC was originally designed for passive tags. Tags draw power entirely from the ambient magnetic field while transmitting and receiving commands bidirectionally.
The NFC transmitter generates a steady 13.56 MHz alternating RF magnetic field. Electromagnetic energy is transferred to the remote device via inductive coupling and converted into direct current through rectification for charging. NFC WLC 2.0 merely increases the output power of this magnetic field to enable charging for small devices. As long as the carrier remains active, standard NFC data packets can be inserted at any time to support continuous charging while performing bidirectional data read/write operations and exchanging device information.
