Fully simultaneous information on variation in status for an object with a dual interface

摘要

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.
