The disclosed embodiment provide different methods for NFC tag detection without impacting A4WP wireless charging. In an exemplary method, dedicated NFC reader is used to interleave the NFC and A4WP signals on the same coil. In one implementation the signals are frequency-multiplexed. In another implementation, the signals are time-multiplexed.
