Abstract: A method for controlling the flow of data in a near field communication appliance having an interposed element and a plurality of secure elements connected to the interposed element is disclosed. The method includes receiving a first communication at a first one of the secure elements. The first communication is sent by an external appliance and suited to an application located in one of the secure elements. The method further includes testing, by means of the first secure element, whether the first secure element contains the application. The first secure element is muted if the first secure element does not contain the application. A corresponding near field communication appliance and terminals are also disclosed.
