An electronic communication apparatus comprising an electronic communication apparatus comprising a control unit with a digital processor electronically coupled to an infrared sensor and to a wireless near field magnetic transceiver for communication with a portable electronic device. The infrared sensor is configured for detection of infrared radiation in a selected area in the vicinity of the detector and for creating an activity signal upon detection of movement of an infrared radiation source in the area. The activity mode implies causing the transceiver to transmit a wireless data signal as a request for receiving a wireless response signal with an ID from a portable electronic device.
