Abstract: Operating an NFC device to communicate with an NFC tag may include converting the NFC device between operating in a standby mode or an active mode, based on whether communication between the NFC device and an NFC tag is failed while the NFC device is operating in an active mode, detecting an NFC tag based on a tag detection sensitivity associated with the NFC device operating in the standby mode, converting the NFC device to operating in the active mode when an NFC tag is detected in the standby mode and adaptively controlling the tag detection sensitivity based on one or more user environment parameters associated with the NFC device. Power consumption and the tag detection sensitivity may be optimized based on adaptively controlling the tag detection sensitivity based on the one or more user environment parameters.
