Abstract: The device may include a contactless element and a set of least two auxiliary elements. Each auxiliary element may include a slave SWP interface connected to a same master SWP interface of the contactless element through a SWP link, and a management module configured for activating at once only one slave SWP interface on the SWP link.

Abstract: An intelligent portable object has a dual interface and is equipped with a chip and is suitable for communicating with at least one electronic data transmission terminal via a contact interface according to standard ISO7816.3 and likewise without contact via a contactless interface and according to another contactless standard; a transition causing a variation of at least one status for the object. At least one information step, for example in real time, of the chip restituting variations in status, with at least a logical phase forming a supply controller, which ensure a configuration/information allowing a fully simultaneous functioning of applications resorting to the contact and/or contactless interface.

Abstract: The invention relates to a method for creating immunity to the variations in resources of a portable object comprising a processor block, and at least two communication and/or supply interfaces with and/or without contact. Said method comprises at least one step for controlling the availability state of at least one resource on one of the interfaces, and a resource selection step. The inventive method is characterised in that it comprises the following steps according to which an interruption signal is generated towards the processor block during a variation in the availability of the resource, and the processor treats the interruption signal in order to enable a selection of resources. The invention also relates to the associated portable object.

Abstract: The invention relates to the operational maintenance of an intelligent portable object (1) which is provided with a processing unit (6) having at least two communication and/or feed interfaces either with or without contacts. The method comprises a reinitialization step (MaZ) for the processing unit (6). The method is characterized in that it comprises at least one delay and/or reinitialization simulation step if a communication or application is in the process of being processed by the processing unit. The invention also relates to an associated device.
