1. A portable electronic device comprising:

  • a near field communication unit configured to receive a control signal, the near field communication unit being switchable, in response to the control signal, between a first mode in which the near field communication unit generates a radio frequency field and a second mode in which the near field communication unit does not generate a radio frequency field;

    a motion sensor unit configured to record a motion of the portable electronic device and to output a motion signal descriptive for the recorded motion; and

    a processing unit configured to receive and analyze the motion signal to detect a first predefined motion pattern including a first phase of acceleration and a second phase of deceleration, and to transmit a control signal to switch the near field communication unit in the first mode upon detection of the first predefined motion pattern.
