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.

Claims

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.
