Abstract: In accordance with a first aspect of the present disclosure, a near field communication (NFC) device is provided, comprising: an NFC transceiver configured to communicate with an external NFC device and to apply at least one transceiver parameter when communicating with the external NFC device; a calibration unit operatively coupled to the NFC transceiver and configured to calibrate the NFC transceiver; wherein the calibration unit is configured to calibrate the NFC transceiver by causing the NFC transceiver to apply different values of the transceiver parameter, measuring a noise level in the NFC transceiver for each applied value of the transceiver parameter, and selecting an optimal value from the applied values of the transceiver parameter in dependence on the noise level measured for each applied value. In accordance with a second aspect of the present disclosure, a corresponding method of operating an NFC device is conceived.
