Fully simultaneous information on variations in status for an object with a dual interface
First Claim
1. A process for allowing simultaneous functioning of a contact interface device and a contactless interface device in an intelligent portable data object, wherein:
- said contact interface device and said contactless interface device have respective power supplies that include a plurality of operating states, andsaid intelligent portable data object is configured to reset in the event of simultaneous operation of both of said interfaces,said process including;
in the event of a change in state of one or more of said power supplies, storing in a memory device information corresponding to the change in state; and
based on the stored state information, preventing the reset of the portable data object by the contact interface.

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.
