The invention is aimed at solving the problem of selection of an application and/or configuration in a device of an NFC system having no independent power source or when the power source of the device is temporarily out of operation or does not have an independent power source. To that end, a wireless mobile communication device of an NFC system according to the invention comprises—a sensor of the accelerometer (Ace) type to produce a signal detecting the movement of the said device while the sensor is powered by a field emitted by a coupler close to which the said device is brought,—a processor (Pro) for comparing the said movement detection signal with a predetermined sequence corresponding with an application and/or configuration, and accordingly selecting the said application and/or configuration if the comparison is positive.
