1. An electronic device comprising:
- near field communication circuitry configured to receive a control signal, the near field communication circuitry being switchable, in response to the control signal, between a first mode in which the near field communication circuitry generates a radio frequency field to communicate with another electronic device and a second mode in which the near field communication circuitry does not generate the radio frequency field to communicate with the another electronic device;
motion sensor circuitry configured to record motion of the electronic device and to output a motion signal descriptive of the recorded motion; and
processing circuitry configured toreceive and analyze the motion signal to detect, in the motion signal, a first predefined motion pattern including a first phase of acceleration and a second phase of deceleration, andtransmit the control signal, to the near field communication circuitry, to switch the near field communication circuitry from the second mode in which the near field communication circuitry does not generate the radio frequency field to communicate with the another electronic device to the first mode in which the near field communication circuitry generates the radio frequency field to communicate with the another electronic device upon detection of the first predefined motion pattern in the motion signal, whereinthe processing circuitry is configured to not transmit the control signal to switch the near field communication circuitry from the second mode to the first mode when another motion pattern, different from the first predefined motion pattern, is detected in the motion signal.

Abstract
A portable electronic device (110) with a NFC (near field communication) unit (114) is switchable between an active mode and a passive mode. A motion sensor unit (112) records a motion of the portable electronic device (110), and outputs a motion signal descriptive for the recorded motion. A processing unit (111) analysis the motion signal to detect a first predefined motion pattern including an acceleration and a deceleration phase. The NFC unit (114) is switched into the active mode upon detection of a first predefined motion pattern descriptive for an NFC touch gesture.
