Abstract: It is described a method, a control device, and a computer program for enabling/disabling at least one near field communication (NFC) function of a mobile device (MD). It is further described such a MD. The method comprises (a) associating the at least one NFC function to be enabled/disabled with a corresponding secure application (SA) installed in a secure element (SE) system; (b) checking whether the SA complies with a predefined secure condition; (c) if the SA complies with the predefined secure condition, transmitting a notification from the SA to the NFC control system (NFCC) via an interface between the SE system and the NFCC; and (d) enabling/disabling, by the NFCC, the at least one NFC function based on information comprised by the transmitted notification.

Abstract: In accordance with a first aspect of the present disclosure, a near field communication (NFC) device is provided, comprising: an NFC front-end circuit configured to perform a communication with an external device; at least one processing unit configured to process one or more transactions between the NFC device and the external device; an NFC controller configured to control the NFC front-end circuit; wherein the NFC controller is configured to block a current data frame, which is being received by the NFC front-end circuit, if the processing unit has not fully processed a previous data frame. In accordance with a second aspect of the present disclosure, a corresponding method of operating a near field communication (NFC) device is conceived. In accordance with a third aspect of the present disclosure, a corresponding computer program is provided.
