Abstract
It is provided an electronic device (70) comprising a communication module (72) adapted to receive signals sent by an NFC reader (90) and adapted to send signals addressed to the NFC reader. The device also comprises a detector (74) coupled to the communication module and adapted to detect load-modulated signals among received signals. The detector is also adapted to prevent the communication module from sending a signal when the detector detects a load-modulated signal. The electronic device improves the field of near field communication.
