Abstract:
A device, including a main element (ME) and a set of at least two auxiliary elements (SEi), said main element including a master SWP interface (MINT), each auxiliary element including a slave SWP interface (SLINTi) connected to said master SWP interface of said NFC element through a controllably switchable SWP link (LK) and management means (PRMprocessor, CTLM, AMGi) configured to control said SWP link switching for selectively activating at once only one slave SWP interface on said SWP link.
