Patent ID: 8718549

Claim:
A mobile wireless communications device comprising: a satellite position determining device; a near-field communication (NEC) device, said NFC device being switchable between a first NFC mode and a second NFC mode, the second NFC mode providing a lower power consumption by said NFC device compared to the first NFC mode; and a controller coupled with said satellite position determining device and said NFC circuit, said controller being configured to switch said NFC device from the first NFC mode to the second NFC mode based upon a determination of movement of the mobile wireless communications device at a rate faster than a threshold rate based upon said satellite position determining device, determine a change in movement to a rate below the threshold rate based upon said satellite position determining device, determine whether a geographical position of the mobile wireless communications device corresponds to a roadway based upon said satellite position determining device, and switch said NFC device from the second NFC mode to the first NFC mode based upon the change in movement to the rate below the threshold rate and a determination that the geographical position does not correspond to a roadway.
