1. A method of operating a near field communication (NFC) device, the method comprising:

  • 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 the NFC device determining whether the NFC reader recognizes the response,wherein the NFC device increases a bandwidth of the NFC device during the signal transmission interval by changing the RF configuration parameter, when the NFC reader does not recognize the response.
