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. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A method for enabling/disabling at least one Near Filed Communication, NFC, function of a mobile device having an NFC control system and a Secure Element, SE, system, the method comprising: associating the at least one NFC function to be enabled/disabled with a corresponding secure application installed in the SE system; checking whether the secure application complies with a predefined secure condition; if the secure application complies with the predefined secure condition; transmitting a notification from the secure application to the NFC control system via an interface between the SE system and the NFC control system; and enabling/disabling, by the NFC control system, the at least one NFC function based on information comprised by the transmitted notification. ### Claim 17 (depends on 16) The method as set forth in claim 16, wherein the notification comprises a secure application identifier. ### Claim 18 (depends on 17) The method as set forth in claim 17, wherein the notification further comprises an action information indicating what action is to be taken by the NFC control system. ### Claim 19 (depends on 16) The method as set forth in claim 16, further comprising: comparing, by the NFC control system, the transmitted notification with at least a part of an access control list stored in the NFC control system; and recognizing, by the NFC control system, that the transmitted notification corresponds to at least a part of the access control list. ### Claim 20 (depends on 16) The method as set forth in claim 16, wherein the predefined secure condition further comprises activating the secure application by a trusted entity. ### Claim 21 (depends on 16) The method as set forth in claim 16, wherein the predefined secure condition further comprises authenticating the secure application by a trusted entity. ### Claim 22 (depends on 16) The method as set forth in claim 16, wherein the predefined secure condition comprises a previous reception of a security command by the SE system, wherein the security command has been forwarded by a trusted entity to the SE system via a secure channel. ### Claim 23 (depends on 16) The method as set forth in claim 16, wherein the predefined secure condition comprises a predefined event occurring during an execution of the secure application. ### Claim 24 (depends on 16) The method as set forth in claim 16, wherein associating the at least one NFC function to be enabled/disabled with a corresponding secure application installed in the SE system comprises a dynamic mapping. ### Claim 25 (depends on 16) The method as set forth in claim 16, wherein the SE system is realized by means of an internal data processing unit being embedded in the mobile device. ### Claim 26 (depends on 16) The method as set forth in claim 16, wherein the SE system is realized by means of an external data processing unit being connected to the mobile device. ### Claim 27 (depends on 16) The method of claim 16, wherein the method is implemented in a computer program stored in a non-transitory media executable by a data processor. ### Claim 28 A control device for enabling/disabling at least one Near Filed Communication, NFC, function of a mobile device, the control device comprising: an NFC control system; a Secure Element, SE, system, which is connected to the NFC control system via an interface; and a processor for controlling the operation of the NFC control system and/or of the SE system by: associating at least one NFC function to be enabled/disabled with a corresponding secure application installed in the SE system; checking whether the secure application complies with a predefined secure condition; if the secure application complies with the predefined secure condition; transmitting a notification from the secure application to the NFC control system via an interface between the SE system and the NFC control system; and enabling/disabling, by the NFC control system, the at least one NFC function based on information comprised by the transmitted notification. ### Claim 29 (depends on 28) The mobile device of claim 28 further comprising a Radio Frequency, RF, antenna arrangement being connected to the control device such that RF data signals can be exchanged between the NFC control system of the control device and the RF antenna arrangement. ### Claim 30 (depends on 29) The mobile device as set forth in claim 29, further comprising an interface for connecting the mobile device to an external entity, in particular via a secure channel.
