Abstract: The present invention concerns the field of the emulation of contactless payment cards and more particularly the routing of the contactless communication within a device comprising several contactless payment card emulation circuits. The invention proposes a method for routing messages within an NFC controller. This controller has a table of the various applications hosted by the various secure elements. When the controller receives a request for the list of applications contained in the virtual payment card, it intercepts this request and responds with the list of the various applications accessible on the various secure elements. When a request aimed at selecting an application is received, the controller stores the secure element concerned and redirects all the messages to this element as long as it does not receive any new selection request.
