A method for controlling the flow of data in a near field communication appliance having an interposed element and a plurality of secure elements is disclosed. The method includes: receiving a first communication, sent by an external appliance, which is intended for an application located in one of the secure elements; determining whether a first one of the secure elements contains the application; and deactivating an interface from the interposed element to the first secure element if the first secure element does not contain the application. Corresponding systems and appliances for near field communication are also disclosed.
