Abstract:
A method of detection of the presence, by a first NFC device, of a second NFC device, during periodic field emission bursts, where detection thresholds are adjusted according to results obtained during one or a plurality of previous bursts.

Claim (Index 12):
A near field communication (NFC) device, comprising:\n an antenna configured to emit a first emission field having a first duration; an oscillating circuit configured to receive a current return signal in response to the first emission field; and a processor configured to:\n determine a phase of the current return signal and an amplitude of the current return signal; \n compare the phase of the current return signal and the amplitude of the current return signal to current phase thresholds and current amplitude thresholds, respectively; \n update the current phase thresholds and the current amplitude thresholds based on the phase of the current return signal and the amplitude of the current return signal, respectively, and in response to a determination that the phase of the current return signal and the amplitude of the current return signal are within the current phase thresholds and the current amplitude thresholds, respectively; and \n determine that a second NFC device is in proximity to the NFC device in response to a determination that at least one of the phase of the current return signal or the amplitude of the current return signal is outside of the current phase thresholds or the current amplitude thresholds, respectively.
