Methods and Appliances for Forwarding Communication Between Electronic Appliances

A terminal, comprising:

• a near field communication appliance, comprising:
• a plurality of secure elements;
• and
• an interposed element connected to the secure elements in a transparent manner, the interposed element being operable to temporarily change from a transparent connection mode to a buffered connection mode with at least one of the secure elements,
• wherein the near field communication appliance is operable to:
• receive a first communication, sent by an external appliance, which is intended for an application located in one of the secure elements;
• determine which secure element contains the application;
• and
• forward the first communication by means of the interposed element to the secure element which contains the application.

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 in a transparent manner, the method comprising:

• receiving data, sent by an external appliance, by the interposed element;
• simultaneously transmitting the data from the interposed element to a first one of the secure elements in a transparent manner by the interposed element, and decoding the data by the interposed element;
• scanning the decoded data by the interposed element to detect a piece of application selection information;
• use the detected piece of application selection information to determine which of the secure elements contains a suitable application;
• temporarily deactivating the transparency of the interposed element by means of buffer storage of the data in the interposed element;
• and
• forwarding the data based on the application selection information to the secure element with the suitable application.
