Abstract:
A method of operating a near field communication (NFC) device includes receiving, by the NFC device, a first signal from an NFC reader, transmitting, by the NFC device, a response to the first signal to the NFC reader and changing selectively, by the NFC device, a radio frequency (RF) configuration parameter associated with signal transmission operation during a signal transmission interval, based on determining whether the NFC reader recognizes the response.
